Purpose: The Hoffa-like tibial plateau fracture is a rare intra-articular fracture and few studies have investigated its curative effect after treatment. We aimed to focus on patients with Hoffa-like tibial plateau fractures based on a large sample population and to evaluate their long-term surgical outcomes treated with open reduction and internal fixation (ORIF). Method: Between August 2017 and September 2020, a period in which 3256 tibial plateau fractures were treated in five trauma centres. Among them, patients with Hoffa-like tibial plateau fractures who treated with ORIF were retrospectively reviewed. Baseline characteristics, operative information, imaging findings, functional scores and any complications were accurately recorded. Each patient was followed for at least three years. Results: Hoffa-like tibial plateau fractures account for approximately 0.9% (29/3256) of all tibial plateau fractures, including 19 males and ten females with a mean age of 45.8 years. After surgery, all patients obtained anatomical reduction of the fractures and none experienced reduction loss. The final Hospital for Special Surgery score (HSS) was improved compared to one year postoperatively (92.76 ± 3.52 versus 89.03 ± 3.81, P < 0.01). No significant differences (P > 0.05) were found in VAS pain score, Rasmussen score, tibial plateau angle (TPA), and posterior slope angle (PSA) between one year and final follow-up. No serious postoperative complications occurred during the treatment and follow-up. Conclusion: Long-term follow-up results showed that patients with Hoffa-like tibial plateau fractures can achieve stable fracture fixation, low postoperative complications, excellent radiographic findings and good functional recovery with ORIF.

Background: Hyperextension varus tibial plateau fracture (HVTPF) is known to present with concomitant injuries to the posterolateral corner (PLC). However, the exact rate and characteristics of these injuries remain unclear. The primary objective of this study was to explore the rate and characteristics of PLC injuries in HVTPFs. The secondary objective was to investigate the relationship between the fracture morphological features and the associated PLC injuries. Methods: Patients with HVTPFs were subdivided into 2 groups: group I (without fracture of the posterior column cortex) and group II (with fracture of the posterior column cortex). Fracture characteristics were summarized qualitatively based on fracture maps and quantitatively based on the counts of morphological parameters. Knee ligamentous and meniscal injuries were assessed using magnetic resonance imaging. The association between fracture characteristics and PLC injuries was analyzed. Results: We included a total of 50 patients with HVTPFs in our study: 28 in group I and 22 in group II. The rate of PLC injuries was 28.6% in group I and 27.3% in group II. In group I, patients with PLC injuries showed fracture lines closer to the anterior rim of the medial plateau and had smaller fracture areas. Furthermore, 6 of the 8 patients with PLC injuries in group I also had posterior cruciate ligament injuries. Conclusions: The rate of PLC injuries is relatively high in HVTPFs. In HVTPFs without fracture of the posterior column cortex, a small fracture area strongly suggests an accompanying PLC injury, and PLC injury is frequently combined with posterior cruciate ligament injury. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence. [ABSTRACT FROM AUTHOR]

Background: The optimal surgical technique for treating tibial plateau fractures remains controversial. This study aimed to compare the outcomes of arthroscopy-assisted reduction and internal fixation (ARIF) to those of open reduction and internal fixation (ORIF) in treating tibial plateau fractures. Methods: This systematic review and meta-analysis were conducted to compare surgical outcomes between ARIF versus ORIF for patients with tibial plateau fractures. Relevant studies, comprising randomized controlled trials (RCTs) and non-RCTs, were identified through searches in Cochrane CENTRAL, PubMed, and Embase databases. Risk of bias assessments were conducted using the revised Cochrane risk-of-bias tool for RCTs (RoB 2.0), Newcastle Ottawa scales for non-RCTs, and Joanna Briggs Institute Critical Appraisal Checklist for case series studies. Data synthesis utilized a random-effects model meta-analysis. The primary outcome assessed was functional outcomes, with complications considered as secondary outcomes. Results: There were fifteen studies (one RCT and fourteen non-RCTs) included in this study, comprising a total of 969 participants (548 in the ARIF group and 421 in the ORIF group). Although patients in the ARIF group showed a trend towards better functional outcomes compared to the ORIF group, the difference was not statistically significant (Hospital for special surgery score, mean difference (MD) = 5.13, 95% confidence interval (CI)=-1.67 to 11.92, I²=83%; Knee society score, MD = 5.84, 95% CI=-1.18 to 12.86, I²=74%). No significant differences were noted in infection, stiffness, DVT, and overall complications between two groups. The ARIF group included ten case series studies with a total of 302 patients. The pooled mean Rasmussen Radiological Score was 16.59 (95% CI, 15.72 to 17.50), and the pooled mean Rasmussen Clinical Score was 27.38 (95% CI, 26.45 to 28.33). Conclusion: The findings of this study reveal no significant difference in clinical outcomes and complication rates between ARIF and ORIF. Additionally, this study found that the complication rate for patients undergoing ARIF falls within previously reported ranges. This suggests that ARIF is a reliable and effective surgical option for treating tibial plateau fractures, even in cases involving high-energy trauma. [ABSTRACT FROM AUTHOR]

Objective: Acute compartment syndrome (ACS) is a serious medical condition that can be encountered in tibial plateau fractures. However, no studies of compartment pressure changes in patients with tibial plateau fractures compared to patient without fractures have been reported. To obtain a comprehensive understanding of the pressure changes in patients with fractures, we monitored and recorded the compartment pressure and attempted to reveal the potential pressure release function of the human fascia. Materials and methods: Cohorts of 43 normal individuals and 23 patients (initial 33, 10 were excluded due to inclusion criteria) and include the number of patients who completed the study with closed tibial fractures (the fracture group, FG, which comprised 6 men and 17 women) were included in this retrospective research. Compartment pressures were measured with Icare, a device that is traditionally used to measure intraocular pressure. Results of measurements at 6 different locations in the lower limb were recorded and compared for three days (days 2, 3, and 4 post fracture) between normal cohort (CG) and fracture cohort (FG) patients. Results: The compartment pressures were comparable at each pressure measurement site (upper, middle and lower) in patients of the CG and the FG. Compared with the CG patients, there was a significant increase in compartment pressure at the upper lateral location in 18-45-year-old patients in the FG (P = 0.013) and at the upper lateral (P = 0.004) and medial locations (P = 0.005) in 46-69-year-old patients, and the values tended to normalize over time. Compared with the contralateral normal limb of patients in the FG, there was a significant increase in compartment pressure at the upper lateral location in 18-45-year-old patients (P = 0.009) and at the upper lateral (P = 0.015) and medial locations (P = 0.016) in 46-69-year-old patients on the fractured side. Based on different fracture classifications, there were no significant differences in compartment pressure at the medial (upper, middle and lower) locations when compared with pressures at the corresponding lateral sites of measurement. Conclusion: The results of this study revealed that the fascial compartment as a whole can release the increased intracompartment pressure after fracture to prevent complications such as acute compartment syndrome caused by a continued increase in pressure. The Icare as a portable device, is potentially useful in compartmental pressure measurement especially in emergency room. [ABSTRACT FROM AUTHOR]

Background/Objectives: 3D patient-specific corrective osteotomies are optimized for use with oscillating saws, thereby rendering it incapable of executing curved osteotomies. The aim of this technical note is to introduce and evaluate the Panflute technique, which facilitates curved osteotomies with precise depth control for intra-articular corrective osteotomies in posttraumatic tibial plateau malunions. Methods: A 33-year-old male patient with an intra-articular malunion was treated one year after index surgery of a lateral split-depression tibial plateau fracture with the Panflute technique. The guide design allowed for multiple drill trajectories in a curved path, recreating the original fracture lines. Cylindrical drill tubes in the guide were tailored to match bone trajectory length. This resulted in a patient-specific Panflute-like design enabling precise depth control, safeguarding posterior neurovascular structures. Secondly, the recreated fragment was reduced with a reduction guide, applied to the plate in situ, to facilitate reposition using the plate as tool and reference. Results: The procedure went without technical drawbacks or surgical complications. Postoperative assessment showed that repositioning of the osteotomized articular fragment was performed accurately: pre- to postoperative translational corrections were 5.4 to 0.5 mm posterior displacement for AP deformity (x-axis); 2.9 to 1.0 mm lateral to medial reduction (y-axis); and 5.9 to 0.6 mm cranial-caudal correction (z-axis). Clinically, at 3 months, the fracture united, the patient regained full flexion, and valgus defect-laxity resolved. Conclusions: The presented Panflute-osteotomy guide allows for a pre-planned curved osteotomy. Additionally, for every drill trajectory, the depth could be controlled. The proposed method may expand our surgical armamentarium of patient-specific 3D techniques and solutions for complex intra-articular osteotomies. [ABSTRACT FROM AUTHOR]

The recovery process after tibial plateau fractures varies, with some patients experiencing persistent gait asymmetries for a long period of time. The aim of this study is to analyse knee joint kinematics and kinetics post-fracture using a linear mixed-effects model, assessing 26 participants over 24 months (aged 45, range 26–63), and an age-matched control group (aged 47, range 26–62). Participants underwent three-dimensional gait analysis at 6-, 12- and 24-months post-injury. Controls participated in the gait analysis on one occasion. Six gait variables related to knee joint kinematics and kinetics were analysed with a linear mixed-effects model. The model was constructed to determine if there was a differential improvement over time between the injured and the non-injured legs across the six variables, referred to as an interaction effect. If no interaction effect was observed, the model assessed whether there was a side difference between the legs and if there was any improvement over time in both legs. Additionally, non-parametric tests were performed to assess differences between the non-injured leg and the control group across the six variables 24 months after injury. The findings revealed an interaction effect in terms of cumulative absorbed power (p = 0.02, side difference p = 0.06). Other variables showed no interaction effects. Although a side difference between legs was observed for all variables (p < 0.001), only the variables regarding generated power exhibited improvements over time (p = 0.02 respectively). Minimal knee flexion, range of motion, and maximal extending knee joint moment showed no improvements over time. At the 24-month follow-up, the maximal extending knee joint moment was the only variable that differed between the non-injured leg and controls, with increased moment observed for the non-injured leg compared with the controls (p = 0.03). Taken together, two years post-fracture, patients demonstrated pronounced side differences between the injured and non-injured legs with worse ability to extend the knee joint and to generate power in the injured leg. While the kinetic variables improved over time, there were no improvements observed in kinematic variables. Moreover, the non-injured leg performed similarly to healthy controls in terms of minimal knee flexion, range of motion, and generated and absorbed power. [ABSTRACT FROM AUTHOR]

In recent years, the incidence of tibial plateau fractures (TPF) has been on the rise. Deep vein thrombosis (DVT) may lead to poor prognosis in patients. The systemic immune-inflammation index(SII) are novel biomarkers of inflammation, and this study aims to verify their predictive effect and construct the nomogram model. This study used binary logistic regression analysis to predict the predictive effect of SII on the occurrence of DVT in tibial plateau fracture patients. And use R studio to construct nomogram model. The results showed that Age (1.03 [1, 1.06], p = 0.032), SII (3.57 [1.68, 7.61], p = 0.04), and NC (7.22 [3.21, 16.26], p < 0.001) were independent predictive factors for DVT. The nomogram demonstrated good predictive performance with small errors in both the training and validation groups, and most clinical patients could benefit from them. The nomogram constructed based on SII can assist clinicians in early assessment of the probability of DVT occurrence. [ABSTRACT FROM AUTHOR]

Ellis-van Creveld syndrome (EVC) is a rare disorder with marked valgus knee deformity, and orthopedic surgeons may experience challenges with lower limb treatment. Most previous reports have focused on EVC in childhood and few on its treatment in adulthood. Our patient was a 23-year-old woman with bilateral knee pain and gait abnormalities, with no history of orthopedic treatment. Valgus knee deformities with anterolateral depression of the lateral tibial plateaus and external rotation deformities of the lower legs were observed on radiography. We performed extra-articular osteotomy of the femurs and tibias and soft tissue release. Although the correction of each femur and tibia was good, mild valgus deformity of the lower limbs remained. This may be because the depression of the lateral tibial plateau was not repaired, and no postoperative remodeling was performed. However, 10 years post-surgery, no recurrence of the deformity was observed and walking was stable without pain. [ABSTRACT FROM AUTHOR]

Lateral tibial plateau fractures with significant articular depression and metaphyseal comminution in the setting of osteoporosis are challenging to manage. The subchondral bone defect and capacious cancellous void after surgical elevation of the articular surface is usually filled with nonstructural graft such as autologous cancellous bone graft, allogenic cancellous bone graft, or bone graft substitutes. Reports have shown a high rate of subsidence with these grafts when patients start to bear weight and ultimately failure of the construct. Structural grafts demonstrated stronger mechanical properties and lower subsidence rates. The purpose of this note is to describe a novel surgical technique using structural tricortical iliac crest allograft for the treatment of osteoporotic depressed lateral tibia plateau fracture.

Introduction: Currently there are few opioid prescribing guidelines for orthopaedic fractures. Long-term post-surgical analgesia requirements, understandably, vary between orthopaedic cases. Our study aims to provide detailed information to clinicians and policy makers, on the opioid requirement associations for patients sustaining tibial fractures. Methods: This study reviewed all patients sustaining an isolated tibial fracture at a major trauma centre that were operated on within 1 month of injury, from 2015 to 2022. The total opioid dosage used each month in morphine milligrams equivalents (MME) and the number of days opioids were used each month, within the first-year post-surgery were collected, representing the strength and coverage of opioid analgesia in the post-operative stage, respectively. We compared opioid strength and coverage requirements with types of definitive fracture fixations, location, fracture type and concurrent patient medical comorbidities to assess for any trends. Results: A total of 1814 patients sustaining a combined of 1970 fractures were included in the study. Tibial plateau fractures had the highest opioid strength and coverage requirements in each month and the entire year (p <.05). Across all fracture locations, Ex Fix frame showed higher opioid strength and coverage requirements compared to both IM nailing and plate ORIF. With regard to opioid coverage in the presence of specific comorbidities, only chronic kidney disease (quotient: 1.37, 95% Confidence interval [95%CI] = 1.19–1.55, p =.002) and hypertension (quotient: 1.34, 95%CI = 1.14–1.53, p =.009) showed significance at the 1-year overall level. For opioid strength, Chronic Kidney Disease (quotient: 1.72, 95%CI = 1.41–2.03 p =.005) and COPD (quotient: 1.90, 95%CI = 1.44–2.36, p =.014), show significance at the 1-year overall level. Conclusion: Our study details opioid requirements post-surgery amongst tibial fractures with subgroup analysis assessing opioid needs amongst specific fracture locations, types, surgical techniques and medical comorbidities. This framework aids clinicians in anticipating rehabilitation and assists in risk stratifying patients at injury onset. [ABSTRACT FROM AUTHOR]

PURPOSE: Proximal fibula fractures are often associated with tibial plateau fractures, but their relationship is poorly characterized. The purpose of this study was to better define the relationship between tibial plateau injury severity and presence of associated soft tissue injuries. METHODS: A retrospective review was performed on all operatively treated tibial plateau fractures at a Level 1 trauma center over a 5-year period. Patient demographics, injury radiographs, CT scans, operative reports and follow-up were reviewed. RESULTS: Queried tibial plateau fractures from 2014 to 2019 totaled 217 fractures in 215 patients. Fifty-two percent were classified as AO/OTA 41B and 48% were AO/OTA 41C. Thirty-nine percent had an associated proximal fibula fracture. The presence of a proximal fibula fracture had significant correlation with AO/OTA 41C fractures, as compared with AO/OTA 41B fractures (chi-square, p

Background: Anatomical reduction and stable fixation of complex tibial plateau fractures remain challenging in clinical practice. This study examines the efficacy of using 3D printing technology combined with customized plates for treating these fractures. Methods: We retrospectively analyzed 22 patients treated with 3D printing and customized plates at the Orthopedic Department of the Central Hospital affiliated with Shenyang Medical College from September 2020 to January 2023. These patients were matched with 22 patients treated with traditional plates with similar baseline characteristics. Patients were divided into an experimental group (3D-printed models and customized plates) and a control group (traditional plates). The control group underwent traditional surgical methods, while the experimental group had a preoperative 3D model and customized plates for surgical planning. We compared baseline characteristics and recorded various indicators, including preoperative preparation time, surgical time, intraoperative blood loss, number of intraoperative fluoroscopies, hospital stay duration, fracture healing time, complications, knee joint range of motion (ROM), Rasmussen anatomical and functional scores, and HSS scores. Results: All surgeries were successful with effective follow-up. The experimental group had shorter surgical time, less intraoperative blood loss, and fewer intraoperative fluoroscopies (P < 0.05). At 6 months and 1 year postoperatively, the experimental group had better knee joint HSS scores than the control group. Preoperative preparation time and total hospital stay were shorter in the control group (P < 0.05). There were no significant differences in fracture healing time and follow-up duration between groups. The experimental group showed better knee joint flexion angles (P < 0.05). Rasmussen scores showed no statistical difference between groups (P > 0.05). The incidence of complications was slightly lower in the experimental group but not significantly different. Conclusion: 3D printing technology combined with customized plates for complex tibial plateau fractures enables precise articular surface reduction, significantly shortens surgical time, and reduces intraoperative blood loss. This method improves knee joint function, offering a more effective treatment option. [ABSTRACT FROM AUTHOR]

Introduction: Proximal tibial plateau fractures are common intra-articular injuries that result from either direct axial compressive trauma or indirect coronal trauma. The standard fixation method is bi-columnar dual plating. In cases with additional tibial tuberosity fractures, a thin-profile distal fibular plate can be used for repair. Aim: To assess the clinical outcomes of a combined posteromedial, anterolateral, and thin distal fibular plating of the tibial tuberosity fractures, and also to assess the radiological outcome in complex proximal tibia Schatzker type 5 and 6 fractures with additional tibial tuberosity fractures. Materials and Methods: This prospective study was carried out at the Orthopaedics Department of Saveetha Institute of Medical and Technical Sciences, Chennai, Tamil Nadu, India from January 2017 to January 2022, on 18 patients with tibial plateau fractures (Schatzker type V or VI) associated with tibial tuberosity avulsion fractures. These fractures were fixed with thin-profile distal fibular plates. The functional outcome of the knee joint was assessed after one year, using the Knee Society score. Descriptive statistics were used to compute means, Standard Deviations, and ranges. Student's t-tests and One-way Analysis of Variance (ANOVA) were used to compare the means. The p-value of =0.05 was considered statistically significant. Results: The average age of the study population was 39.4±5.6 years. Road traffic accidents were the most frequent mode of injury in 14 (77%) individuals. No perioperative complications were noted. The average duration of surgery was 114±10.4 minutes, and the average blood loss was 146±40 mL, throughout the procedure. The Knee Society score at 12 months postoperatively was excellent at 93.6 (range 92 to 98). Radiographic bone union was observed after an average of 12.4 weeks. Conclusion: Multiplanar complicated proximal tibia Schatzker type V and VI fractures with tibial tuberosity avulsion fractures may be effectively treated using a novel technique of thin-profile distal fibular plating. The bi-columnar plates combined with open reduction and internal fixation through two incisions with thin distal fibular plates showed satisfactory results. [ABSTRACT FROM AUTHOR]

The article discusses lipohemarthrosis, the accumulation of fat and blood within a joint due to an intraarticular fracture, and its detection through various imaging modalities. It highlights the clinical significance of lipohemarthrosis in diagnosing intraarticular fractures at different joints, such as the knee, shoulder, elbow, wrist, hip, and foot. The use of point-of-care ultrasound is also emphasized as a valuable tool for diagnosing lipohemarthrosis and managing intraarticular fractures, especially in cases where traditional radiography may not be conclusive.

AbstractPosteromedial tibial plateau fracture is one of the most challenging traumatic fractures. We aimed to compare and explain the biomechanical advantages and disadvantages of different internal fixation methods for the treatment of the posteromedial split fracture fragment in tibial plateau fractures. Finite element models of the tibial plateau fracture were constructed. Three different internal fixations were developed to treat the posteromedial split fracture fragment in tibial plateau fractures finite element models: (a) the novel anatomic locking plate fixation model, (b) the common anatomic locking plate fixation model, and (c) the reconstruction plate fixation model. We applied the same loading conditions to each model: 320 N axial compression. Under the same condition, the von Mises stress (VMS) and displacement distribution of the three internal fixations and tibia plateau were studied. The stress values of the novel anatomic locking plate are lower than the common anatomic locking plate and the reconstruction plate. Additionally, the novel anatomic locking plate fixation system exhibits smaller maximum displacement. In conclusion, our study indicated that the novel anatomic locking plate resulted in a lower stress distribution in the plate and screws, and better stability than the common anatomic locking plate and the reconstruction plate for the posteromedial split fracture fragment in tibial plateau fractures fixation under the same loading conditions. Thus, for the posteromedial split fracture fragment in tibial plateau fractures, the use of the novel anatomic locking plate internal fixation is recommended. [ABSTRACT FROM AUTHOR]

Purpose: The 5-item modified frailty index (mFI-5) has been established as a reliable indicator of poor postoperative outcomes following a variety of orthopaedic procedures. This study aims to determine whether the mFI-5 can be used by surgeons to predict the likelihood of postoperative complications in patients undergoing open reduction internal fixation (ORIF) for tibial plateau fractures. Methods: From 2006 to 2019, patients aged 50 years or older undergoing ORIF for tibial plateau fracture were identified in the National Surgical Quality Improvement Program database. The mFI-5 was calculated based on the sum of the presence of 5 conditions: diabetes, congestive heart failure, hypertension, chronic obstructive pulmonary disease, and dependent functional status. Chi-squared tests and multivariable regression analysis were used to evaluate the association of different mFI-5 scores with postoperative complications. Results: The study analyzed 2213 patients with an average age of 63 years. Multivariable regression analysis demonstrated that in comparison to patients with a mFI-5 score of 0, those with a score of 1 had an increased risk of prolonged hospital stay (OR 1.31) and discharge to a non-home location (OR 1.50) while those with a score of 2 or greater were at an increased risk of readmission (OR 2.30), wound complication (OR 5.37), pulmonary complication (OR 4.56), urinary tract infection (OR 4.79), prolonged hospital stay (OR 1.89), and discharge to a non-home location (OR 3.01). Conclusion: The mFI-5 is a reliable instrument for determining the likelihood of postoperative complications following ORIF for tibial plateau fracture repair. Level of evidence: III.

Purpose: The purpose of this study was to determine the rates of compartment syndrome and other early complications following outpatient open reduction and internal fixation (ORIF) of tibial plateau fractures. Methods: This was a retrospective cohort at a single US level I academic trauma centre of patients with tibial plateau fractures managed operatively. Inpatients received their definitive ORIF during their index hospital stay and were admitted post-operatively following ORIF. Outpatients were scheduled for ambulatory surgery during definitive ORIF. Exclusion criteria for outpatient surgery included compartment syndrome, polytrauma, open types IIIb/IIIc, and patients who received any internal fixation during index presentation. The primary outcome measure was post-operative compartment syndrome. Secondary outcomes were return to the 90-day return to the ED, 90-day readmission, surgical wound infection, thromboembolism, and 90-day mortality. An intention-to-treat (ITT) and as-treated (AT) analyses were performed. Results: Totally, 71 inpatients and 47 outpatients were included. There were no cases of post-operative compartment syndrome. In the ITT analysis, there were no differences for inpatients vs outpatients for 90-day re-admission (22.5% vs 12.8%, p = 0.275), 90-day return to the ED (35.2% vs 17.0%, p = 0.052), infection (12.7% vs 2.1%, p = 0.094), DVT (7% vs 4.3%, p = 0.819), or PE 1.4% vs 0.0%, p = 1.000). The AT analysis showed a significantly higher 90-day re-admission (26.9% vs 2.5%, p = 0.003) and 90-day ED visit (38.5% vs 7.5%, p = 0.001) rate in the inpatient group. Conclusions: Appropriately selected patients with isolated tibial plateau fractures can have non-inferior rates of compartment syndrome and post-operative complications when compared to inpatients.

Purpose: To investigate the qualitative and quantitative changes seen in quadriceps muscles [QM] following tibial plateau fracture and surgery. Methods: A consecutive series of patients with an isolated tibial plateau fracture presenting to a single academic center were enrolled and prospectively followed. Bilateral knee MRIs were performed preoperatively and 3 and 12 months postoperatively to assess quantity and quality of the quadriceps muscles. All patients underwent tibial plateau operative repair and were made non-weight-bearing for 10 weeks postoperatively then advanced to weight-bearing as tolerated. Functional status assessed via the short musculoskeletal functional assessment (SMFA); knee range of motion [ROM]; vastus medialis oblique [VMO] and vastus lateralis [VL] muscle quantity (axial width, cross sectional area [CSA] and volume) on injured and contralateral limb; VMO, sartorius, semi-membranous and biceps femoris [BF] muscle quality (fat and water content, and proton density fat fraction). All muscle quantitative and qualitative measurements were compared across all time points. Results: Ten patients were included in the final analysis, 6 males and 4 females, with average age of 43.62 ± 16.3 years. While the VMO and VL axial width and CSA were significantly decreased at 3 months preoperatively, this was not statistically significant. There was no significant difference between any QM quantitative measurements at any time points. There was no difference in fat content, water content or PDFF at any time point for the VMO, sartorius, semi-membranous and BF muscles. Regression analysis also showed no association between 12-month SMFA scores and knee ROM with VMO/VL CSA at 1 year. Conclusions: QM quantity and quality do not significantly change at 3 months and 1 year postoperatively following tibial plateau fracture surgery. Level of evidence: Prognostic Level II.

Background: Schatzker type II fractures usually need to be grafted. Autograft bone from the iliac crest represents the gold standard, but it comes with high rates of morbidity on the donor side. Sticky bone is one of the regenerative therapies that aims to find new solutions to treat bone defects and to overcome the limitation of conventional options regarding bone grafts, due to their content in growth factors, which offer osteo-induction and osteo-conduction properties. Notably, regenerative dentistry has been at the forefront of applying these products in bone regeneration, demonstrating that PRF produces a highly promising "sticky bone" when combined with bone chips. To the best of our knowledge, this grafting technique has not been used in the orthopedic field to date. Methods: The subject was a 53-year-old woman with a Schatzker type II tibial plateau fracture, for which a new autologous bone grafting technique, i.e., sticky bone, was used for the treatment of the fracture. Results: This case reports the effectiveness of sticky bone as autologous bone graft used in Shatzker type II tibial plateau fracture. As an indispensable component of regenerative medicine, it seems to be an ideal biologic graft with a fibrin-rich structure that provides effective treatment in impressed tibial plateau fractures. Conclusion: Sticky bone showed promising results and should be considered in the future as an appropriate bone implant. [ABSTRACT FROM AUTHOR]

Lateral platform collapse in fixations of lateral tibial plateau fractures (TPFs) using either double‐lag screws fixation (DSF) or locking‐plate fixation (LPF) is not rare. This study aimed to explore the effect of enhancing the interfragmentary compression force (IFCF) on fixation stability in lateral TPFs in normal and osteoporotic bones using finite element analysis. Finite element models of DSF in normal bone and LPF in normal and osteoporotic bones were established to simulate the fixations of lateral TPF. After model validation, axial compressive forces of 500, 1000, 1500, and 2500 N to the tibial plateau along with an IFCF of 0, 100, 200, and 300 N were applied. The maximum axial micromotion of the lateral fragment (MAM‐LF), maximal translational micromotion of the lateral fragment (MTM‐LF), peak von Mises stress (VMS), and peak equivalent elastic strain of the lateral fragment (EES‐LF) were evaluated. The MAM‐LF showed a decreasing trend as the IFCF increased in all models. For DSF models, the peak VMS of implants increased as the IFCF increased when the axial loads were 500 and 1000 N. The peak EES‐LF decreased as the IFCF increased under axial loads of 1000, 1500, and 2500 N. For the normal and osteoporotic LPF models, the peak VMS of the implants decreased as the IFCF increased. Peak EES‐LF decreased as IFCF increased. In conclusion, enhancing IFCF was beneficial in improving the fixation stability of lateral TPF. The optimal IFCF for DSF and LPF should be as high as reasonably feasible. [ABSTRACT FROM AUTHOR]

Background Context: This study's purpose was to evaluate the biomechanical performance of plate–nail and dual-plate fixation for the treatment of AO/OTA 41-C2 tibial plateau fractures. Methods: Twenty synthetic tibias were selected and randomly divided into a plate–nail group (n = 10) and a dual-plate group (n = 10). After the artificial tibias were osteotomized to simulate AO/OTA 41-C2 tibial plateau fractures in both groups, the plate–nail and the dual-plate methods, respectively, were used for fixation, and then axial compression loading, three-point bending, torsion, and axial failure tests were carried out. The data of each group were recorded and statistically analyzed. Results: In the axial compression test, the average stiffness of the plate–nail group was higher than that of the dual-plate group (p < 0.05). The displacement generated in the plate–nail group was significantly smaller than that in the dual-plate group (p < 0.05). In the resisting varus test, the stress of the plate–nail group was significantly higher than that of the dual-plate group (p < 0.05). In the resisting valgus test, the stress of the plate–nail group was slightly higher than that of the dual-plate group, but the difference was not statistically significant (p > 0.05). In the static torsion test, the load applied to the plate–nail group was smaller than that of the dual-plate group when rotated to 5° (p < 0.05). In the axial compression failure test, the average ultimate load of the plate–nail group was significantly higher than that of the dual-plate group (p < 0.05). Conclusion: The treatment of AO/OTA 41-C2 tibial plateau fractures with plate–nail fixation is superior to that with dual-plate fixation in resisting axial stress and preventing tibial varus deformity, while dual-plate fixation has better resisting torsional ability.

Background: In elderly tibial plateau fractures (TPFs), the lateral condyles are involved frequently. This study aimed to compare the outcomes of open reduction and internal fixation (ORIF) and double reverse traction repositor (DRTR) assisted closed reduction and internal fixation (CRIF) in elderly patients with lateral TPFs. Methods: From January 2015 to July 2020, we retrospectively reviewed 68 patients treated surgically at our trauma center for lateral TPFs (Schatzker type I-III). 31 patients were eventually assigned to the DRTR assisted CRIF group, whereas 37 patients were assigned to the ORIF group. The primary outcomes included surgical details, radiological assessment, follow-up knee function, and complications. Results: The DRTR assisted CRIF group experienced a 43.6 mL decrease in intraoperative blood loss (161.3 ml vs 204.9 ml, p = 0.033), and the operation duration was 32.1 min shorter than the ORIF group (83.8 min vs 115.9 min, p < 0.001). There was no statistically significant difference in terms of widening of the tibia plateau (WTP), depth of articular depression (DAD), medial proximal tibial angle (MPTA) and posterior tibial slope angle (PTSA) immediately after surgery and at the last follow-up. No differences in malreduction (p = 0.566) or reduction loss (p = 0.623) were observed between the groups, and Lysholm and HSS scores were similar between the two groups (83.6 ± 15.8 vs 83.4 ± 5.1, p = 0.934; 89.3 ± 7.8 vs 86.9 ± 6.2, p = 0.172; respectively). However, ORIF was associated with a greater increase in postoperative complications than DRTR assisted CRIF (3.2% vs 27%, p = 0.008). Conclusion: Both types of internal fixation provide good radiological outcomes and knee function in the treatment of lateral TPFs in the elderly. However, DRTR assisted CRIF has the advantage of a shorter duration of surgery, less blood loss, and fewer postoperative complications, and appears to be a better treatment option for elderly patients with lateral TPFs.

The treatment of complex tibial plateau fractures is a challenge for even experienced orthopedic surgeons. While it is established that type and timing of surgical treatment depends on the involvement of soft tissues, there is no agreement in the literature about post-surgical weight-bearing on the operated limb: it ranges from a total ban to a partial concession of 6 to 12 weeks. Weight-bearing modulation can be difficult in physically challenged or frail patients such as the elderly, with a real risk of hypokinesis, bedridden and related complications. To allow the early treatment of these fractures and immediate weight-bearing, we connected a circular external fixator (CEF) to a hinged knee external fixator (HEF) with specific axial load resistance characteristics. This hybrid technique, which we have called CHEF-K (Circular and Hinged External Knee Fixation), maintains and combines the mechanical characteristics of both devices. In selected cases we early stabilized the fracture in a minimally-invasive way associated with CEF, then protecting the osteosynthesis with HEF which bypassed the fracture during loading while also allowing movement of the knee. In the first case described herein, a 78-year-old woman showed rapid functional recovery, being able to walk without aids after 4 weeks. [ABSTRACT FROM AUTHOR]

Current treatments do not support direct exposure of fracture fragments, resulting in the inability to directly observe the articular surface during surgery for accurate reduction and firm fixation. The aim of the study was to explore the treatment effect of digital virtual reduction combined with individualized guide plate of lateral tibial condyle osteotomy on tibial plateau fracture involving the lateral posterior condyle collapse. 41 patients with tibial plateau fracture involving the lateral posterior condyle collapse were recruited in the trial. All patients underwent Computed Tomography (CT) scanning before operation. After operation, fracture reduction was evaluated using Rasmussen score and function of knee joint was assessed using hospital for special surgery (HSS) score. 41 patients were followed-up 6–26 months (mean, 15.2 months). Fracture reduction was good after operation, with an average of 13.3 weeks of fracture healing without serious complications. The excellent and good rate was 97.6%. The joint movement degree was -5∘∼0∘∼135∘ with an average of 125.5∘. Digital virtual reduction combined with individualized guide plate of lateral tibial condyle osteotomy was effectively for treating tibial plateau fracture involving the lateral posterior condyle collapse.

Background. For a long time, the question of optimal ways and methods of surgical treatment of fractures of the proximal part of the tibia (PPT) remains debatable. The purpose was to study the results of surgical treatment of fractures of the PPT using differentiated use of minimally invasive techniques. Materials and methods. The work consisted of a prospective analysis of the treatment outcomes of 87 patients who were treated 2018 to 2023. Fractures were classified according to Schatzker. The tactics of surgical treatment depended on the type of fracture, the age of the patients and the presence of concomitant diseases. A comprehensive assessment of knee function was performed using the Knee Society Score. For X-ray assessment of the degree of progression of post-traumatic arthritis, the Resnik/Niwoyama system was used. Results. The results of surgical treatment were studied in terms from 6 to 24 months. 19.8 % of excellent, 57.5 % good, 15.6 % satisfactory and 7.1 % unsatisfactory treatment results were obtained. Progression of post-traumatic arthritis was observed in 36 patients (28 patients at one stage, 4 subjects at 2 stages and 5 patients at 3 stages). Of the complications, 7 (8.0 %) were surgical site infections, which required debridement of the focus and longer antibiotic therapy. Over time, loss of reposition and secondary displacement were identified in 5 (5.7 %) cases. The most common complications were the progression of knee osteoarthritis, the development of contractures in 11 (12.6 %) patients. Conclusions. The use of a differential approach to the surgical treatment of intra-articular fractures of PPT, based on the severity of injuries according to Schatzker, allowed to obtain positive functional results in 77.3 % of the victims. The negative consequences of intra-articular fractures of the tibial plateau that worsen the functional outcomes of treatment include the progression of knee osteoarthritis. The degree of its manifestations is largely determined by the severity of the injury, the quality of reduction, the stability of fragment fixation, and the rationality of restorative treatment and rehabilitation.

Purpose: Lateral unicompartmental knee arthroplasty (UKA) is an accepted treatment option in cases of end-stage lateral osteoarthritis. While lateral UKA has many proposed advantages compared to total knee arthroplasty, its technical challenges and relatively small number of cases make this an uncommon procedure. The aim of this study was to report the survivorship and functional outcomes beyond 20 years of follow-up of isolated UKA. Methods: Between January 1988 and October 2003, 54 lateral UKAs were performed in a single center. The fitted prosthesis was a fixed plate and cemented polyethylene (PE). All patients had isolated lateral tibiofemoral osteoarthritis, including five open meniscectomies, three arthroscopies, and three open reductions of lateral tibial plateau fractures. Patients with a minimum of 20 years of follow-up were included in the final analysis. Results: Of the 54 UKA, 22 died before reaching the minimum follow-up period and four were lost to follow-up. Twenty-eight were included in the final analysis. Among them, 21 patients remained alive and an additional seven were deceased after 20 years. The mean age at the last follow-up was 84.8 ± 11.9 years with a mean follow-up duration of 22.5 ± 2.1 years. Of the 28 knees, eight underwent revision surgery (5 for the progression of osteoarthritis; 2 for aseptic loosening; 1 for PE wear). Kaplan–Meier survival analysis revealed a survival rate at 20 and 25 years of 72.3% (CI 59.1; 88.6). The average time to revision was 14.9 ± 4.9 years. At the last follow-up, the mean function Knee Society Score (KSS) was 41.5 ± 32.9 and the mean objective KSS score was 79.4 ± 9.7. In the unrevised population, 94.7% of patients (n = 18) reported being satisfied or very satisfied with the surgery. Conclusion: Lateral UKA remains a viable treatment option for patients with isolated lateral tibiofemoral osteoarthritis, providing satisfactory 20-year implant survivorship and high patient satisfaction.

Purpose: Appropriate management of acute postoperative pain is critical for patient care and practice management. The purpose of this study was to determine whether postoperative pain score correlates with injury severity in tibial plateau fractures. Methods: A retrospective review of prospectively collected data was completed at a single academic level one trauma center. All adult patients treated operatively for tibial plateau fractures who did not have concomitant injuries, previous injury to the ipsilateral tibia or knee joint, compartment syndrome, inadequate follow-up, or perioperative regional anesthesia were included (n = 88). The patients were split into groups based on the AO/OTA fracture classification (B-type vs C-type), energy mechanism, number of surgical approaches, need for temporizing external fixation, and operative time as a proxy for injury severity. The primary outcome measure was the visual analog scale (VAS) pain score (average in the first 24 h, highest in the first 24 h, two- and six-week postoperative appointments). Psychosocial and comorbid factors that may affect pain were studied and controlled for (history of diabetes, neuropathy, anxiety, depression, PTSD, and previous opioid prescription). Additionally, opioid use in the postoperative period was studied and controlled for (morphine milligram equivalents (MME) administered in the first 24 h, discharge MME/day, total discharge MME, and opioid refills). Results: VAS scores were similar between groups at each time point except the two-week postoperative time point. At the two-week postoperative time point, the absolute difference between the groups was 1.3. The groups were significantly different in several injury and surgical variables as expected, but were similar in all demographic, comorbid, and postoperative opioid factors. Conclusions: There was no clinical difference in postoperative pain between AO/OTA 41B and 41C tibial plateau fractures. This supports the idea of providers uncoupling nociception and pain in postoperative patients. Providers should consider minimizing extended opioid use, even in more severe injuries.

Purpose: To determine if subchondral rafting wires retained as adjunctive tibial plateau fracture fixation affect postoperative articular subsidence. Methods: A retrospective cohort study was conducted at one Level 1 trauma center and one academic university hospital. Consecutive adults with closed, displaced OTA/AO 41B/C tibial plateau fractures treated between 2018 and 2023 with open reduction internal fixation were included. Patients who were not ambulatory, with contralateral injuries limiting weight bearing, and without follow-up radiographs of the injured extremity were excluded. The intervention was retention of subchondral rafting wires as definitive fixation. The primary outcome was linear articular surface subsidence between postoperative and follow-up AP knee radiographs. Linear subsidence was compared between groups using Welch's two sample t test. Associations of linear subsidence with patient, injury, and treatment characteristics were assessed by multivariable linear regression. Results: We identified 179 patients of a mean age of 44 ± 14 years, of whom 15 (8.4%) received subchondral rafting wires. Median follow-up was 121 days. No patients who received rafting wires as definitive implants experienced linear subsidence ≥ 2 mm, while 22 patients (13.4%) who did not receive rafting wires experienced linear subsidence ≥ 2 mm (p = 0.130). Subchondral rafting wires were associated with less linear subsidence (0.3 mm [95% confidence interval − 0.3–0.9 mm] vsersus 1.0 mm [− 0.9–2.9 mm], p < 0.001). The depth of linear subsidence was significantly associated on multivariable regression with male sex, depressed plateau area, active smoking, and retained rafting wires. Conclusion: Subchondral rafting wires were associated with a small reduction in articular subsidence after internal fixation of tibial plateau fractures. Routine rafting wires may be useful for patients and fractures at high risk of articular subsidence. [ABSTRACT FROM AUTHOR]

Fixing the posterolateral fragments of tibial plateau fractures has been challenging owing to potential neurovascular injuries and fibular head blocks. Several surgical approaches and fixation techniques have been reported, with distinct limitations. We propose a novel lateral tibia plateau hook plate system and compare its biomechanical stability with other fixation methods. Twenty-four synthetic tibia models were simulated to present posterolateral tibial plateau fractures. These models were randomly assigned to three groups. Group A models were fixed with the lateral tibia plateau hook plate system, Group B with variable-angle anterolateral locking compression plates, and Group C with direct posterior buttress plates. The models' biomechanical stability was evaluated using static (gradually increased axial compressive loads) and fatigue (cyclically loaded from 100 to 600 N for 2000 cycles each) tests. Groups A and C models exhibited comparable axial stiffness, subsidence load, failure load, and displacement in the static test. Group A model exhibited higher subsidence and failure loads than Group B model. Groups A and C models exhibited comparable displacement at 100 N cyclic loading in the fatigue test. Group C model was more stable at higher loads. Group C model endured the highest subsidence cycle numbers, followed by Groups A and B models. The lateral tibia plateau hook plate system provided similar static biomechanical stability as the direct posterior buttress plates and comparable dynamic stability under limited axial loading. This system is a potential posterolateral treatment choice owing to its convenience and safety, in treating tibia plateau fractures. [ABSTRACT FROM AUTHOR]

Background: The aim of this retrospective cohort study was to determine the rate of prolonged opioid use and identify associated risk factors after perioperative opioid exposure for tibial shaft fracture surgery. Materials and Methods: We used the MarketScan Commercial Claims and Encounters database (IBM) to identify patients 18 to 64 years old who filled a peri-operative opioid prescription after open reduction and internal fixation of a tibial shaft fracture from January 2016 to June 2020. Multivariable logistic regression identified factors (eg, demographics, comorbidities, medications) associated with prolonged opioid use (ie, filling an opioid prescription 91 to 180 days postoperatively); adjusted odds ratios (ORs) and 95% CIs were reported. Results: The rate of prolonged opioid use was 10.5% (n=259/2475) in the full cohort and 6.1% (n=119/1958) in an opioid-naive subgroup. In the full cohort, factors significantly associated with increased odds of prolonged use included preoperative opioid use (OR, 4.76; 95% CI, 3.60–6.29; P<.001); perioperative oral morphine equivalents in the 4th (vs 1st) quartile (OR, 2.68; 95% CI, 1.75–4.09; P<.001); age (OR, 1.03; 95% CI, 1.02–1.04; P<.001); and alcohol or substance-related disorder (OR, 1.66; 95% CI, 1.15–2.40; P=.01). Patients in the Northeast and North Central (vs South) regions had decreased odds of prolonged use (OR, 0.61–0.69; P=.02–.04). When removing preoperative use, findings were similar in the opioid-naive subgroup. Conclusion: Prolonged opioid use is not uncommon in this orthopedic trauma population, with the strongest risk factor being preoperative opioid use. Nevertheless, shared risk factors exist between the opioid-naive and opioid-tolerant subgroups that can guide clinical decision-making. [Orthopedics. 2024;47(4):e188–e196.] [ABSTRACT FROM AUTHOR]

Objective Dual‐plate fixation was thought to be the gold standard for treating complicated bicondylar tibial plateau fractures, yet it was found to be hard to accommodate the posterior column in three‐column fractures. Currently, column‐specific fixation is becoming more and more recognized, but no comprehensive investigation has been performed to back it up. Therefore, the objective of this study was to validate the importance of posterior column fixation in the three‐column tibial fractures by a finite element (FE) analysis and clinical study. Methods In FE analysis, three models were developed: the longitudinal triple‐plate group (LTPG), the oblique triple‐plate group (OTPG), and the dual‐plate group (DPG). Three loading scenarios were simulated. The distribution of the displacement and the equivalent von Mises stress (VMS) in each structure was calculated. The comparative measurements including the maximum posterior column collapse (MPCC), the maximum total displacement of the model (MTD), the maximum VMS of cortical posterior column (MPC‐VMS), and the maximum VMS located on each group of plates and screws (MPS‐VMS). The clinical study evaluated the indicators between the groups with or without the posterior plate, including operation time, blood loss volume, full‐weight bearing period, Hospital for Special Surgery Knee Scoring system (HSS), Rasmussen score, and common postoperative complications. Results In the FE analysis, the MPCC, the MPC‐VMS, and the MTD were detected in much lower amounts in LTPG and OTPG than in DPG. In comparison with DPG, the LTPG and OTPG had larger MPS‐VMS. In the clinical study, 35 cases were included. In the triple‐plate (14) and dual‐plate (21) groups, the operation took 115.6 min and 100.5 min (p

This article, published in Seminars in Musculoskeletal Radiology, aims to enhance the understanding of tibial plateau fractures among radiologists. It provides crucial diagnostic considerations and implications for surgical planning. Tibial plateau fractures are periarticular injuries of the proximal tibia that account for 1 to 2% of all fractures. They have a bimodal distribution, with high-energy trauma affecting men in their 40s and low-energy falls affecting women in their 70s. The article explores the Schatzker classification system, which helps assess and categorize these fractures. It also discusses the use of knee radiographs, computed tomography (CT), and magnetic resonance imaging (MRI) in the diagnosis and assessment of these fractures. The goal of the article is to empower radiologists with a deeper understanding of tibial plateau fractures for more accurate diagnosis, refined surgical planning, and improved patient care.
