Background: The role of arthroscopic Latarjet as a revision surgery after failed arthroscopic Bankart repair has yet to be established. Purpose: To compare clinical outcomes, recurrences, and complication rates of arthroscopic Latarjet as a revision procedure after failed arthroscopic Bankart repair versus arthroscopic Latarjet as a primary procedure. Design: Cohort study; Level of evidence, 3. Methods: This is a retrospective study of prospectively collected data of patients who were diagnosed with anterior shoulder instability and underwent arthroscopic Latarjet stabilization between 2009 and 2018. Patients were separated into 2 groups depending on whether Latarjet was performed after a previous instability surgery (revision) or as a primary surgery (primary). Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE) were assessed pre- and postoperatively with a minimum 24 months of follow-up. In addition, pre- and postoperative levels of sports activity, dislocations, subluxations, and complications were assessed. Results: A total of 97 patients (n = 62 revision; n = 35 primary), with a mean age of 31.0 ± 8.8 and 29.4 ± 7.6 years old in the revision and primary Latajet group, respectively, met the inclusion criteria. The mean follow-up in the revision group was 32 months (24-53) and 35.5 months (27.7-42.2) in the primary Latarjet group. No significant differences between groups were observed in Rowe score (revision = 91.4, primary = 94.1; P =.223), CMSO score (revision = 90.7, primary = 94; P =.105), and SANE (revision = 85.8, primary = 87.3; P =.683) postoperatively. However, the postoperative difference in the WOSI score between the revision and primary Latarjet groups was nearly significant (510 ± 334 vs 403 ± 343, respectively; P =.05). Four (6.4%) postoperative dislocations were reported in the revision and 1 (2.8%) in the primary Latarjet group (P =.14). Patients in the revision group had a lower return to the previous level of sports participation (P =.008) and decreased external rotation with the arm by the side compared with the primary Latarjet group (P =.000). Conclusion: Arthroscopic Latarjet as a revision surgery is a reasonable surgical option in failed Bankart repair cases. The decision to perform arthroscopic Latarjet stabilization as a revision surgery should not be influenced by the potential risk of future complications as it provides comparable clinical outcomes to the primary Latarjet procedure with a low postoperative recurrence rate. However, a decreased level of postoperative sports participation and external rotation with the arm by the side can be expected. [ABSTRACT FROM AUTHOR]

Background: The optimal treatment option for meniscus root tears is still challenging, and whether the meniscus root repair ultimately can arrest or delay osteoarthritic changes is still a concern. Purpose/Hypothesis: The purpose of this study was 2-fold: (1) to describe and compare histopathologic findings of 3 different therapeutic options for medial meniscus posterior root tear: nonoperative management, partial meniscectomy, and meniscus root repair; and (2) to test the hypothesis that meniscus root tears treated nonoperatively predispose to a lower risk of osteoarthritic progression compared with partial meniscectomy. Study Design: Controlled laboratory study. Methods: Posteromedial meniscus root tears were carried out in 39 New Zealand White rabbits. Animals were randomly assigned into 3 experimental groups: partial meniscectomy after root tear (PM; n = 13), root tears treated conservatively (CT; n = 13), and transtibial root repair (RR; n = 13). Contralateral limbs were used as healthy controls. The animals were euthanized at 16 weeks postoperatively; tissue samples of femoral and tibial articular cartilage were collected and processed for macro- and microscopic assessment to detect signs of early osteoarthritis (OA). Each sample was histopathologically assessed using the Osteoarthritis Research Society International grading and staging system. Results: Osteoarthritic changes were the hallmark in all 3 experimental groups. The RR group had the lowest scores for cartilage damage (mean, 2.5; range, 2-3), and the PM group exhibited higher and more severe signs of OA (mean, 16; range, 9-16) compared with the CT group (mean, 5; range, 4-6). The between-group comparison revealed significant differences, as the PM group showed a significantly higher rate of macro- and microscopic osteoarthritic changes compared with the RR (P <.001) and CT (P <.001) groups. The weightbearing area of the medial femoral condyle was the most severely affected, and tidemark disruption was evident in all tissue samples. Conclusion: Meniscus root repair cannot completely arrest the histopathologic progression of knee OA but leads to significantly less severe degenerative changes than partial meniscectomy and nonoperative treatment. Partial meniscectomy leads to the most severe osteoarthritic progression, while stable radial tears left in situ have lower progression compared with partial meniscectomy. Clinical Relevance: Histologic assessment is an essential tool and metric for guiding and understanding osteoarthritic features, providing insight into the disease development and progression. This study provides histopathologic evidence on osteoarthritic progression after medial meniscus posterior root repair. This knowledge can help to set more realistic expectations and can lead to the future development of augmented techniques. [ABSTRACT FROM AUTHOR]

Background: Trochanteric bursitis or greater trochanteric pain syndrome is a common disorder and frequent cause of lateral hip pain. It can lead to severe functional impairment with increase morbidity and poor quality of life. The purpose of the current study was to identify and evaluate relationship between health-related factors, as prognostic indicators, and clinical outcomes. Methods: A single-centre, prospective study was conducted and 60 patients (62 hips) were included with a minimum 12 months of follow-up. Clinical outcomes were evaluated using Hip Outcome Scale, Single Assessment Numeric Evaluation and Visual Analogue Scale. Radiological assessments and health-related factors were documented in an attempt to understand their validity as predictors of clinical outcomes. Complications and recurrence rates were also analyzed. Results: Univariate model revealed that an increased BMI (p = 0.001; OR = 1.05; 95% CI, 1.02-1.07); number of previous corticosteroid infiltrations (p = 0.001; OR = 1.28, 95% CI, 1.11-1.48); longer time from symptom onset to surgery (p = 0.001; OR = 1.19; 95% CI, 1.12-1.28); smoker status (p = 0.001; OR 11.2; 95% CI, 3.30-44.2); and the presence of prior lumbosacral fusion (LSF) (p = 0.001; OR 13.8; 95% CI, 2.96--101); were prognostic factors predisposing for poor clinical outcomes. Among prognostic health-related factors were medical comorbidities such as emotional distress (p < 0.001; OR 26.1; 95% CI, 5.71-192); fibromyalgia (p = 0.026; OR 3.56; 95% CI, 1.16-11.7); and hyporthyroidism (p = 0.005, OR = 6.55, 95% CI, 1.73-28.7). Conclusions: Better overall physical function was predicted by lower number of corticosteroid infiltrations, shorter time span from symptom onset to surgery, non-smoker status and the absence of prior lumbosacral fusion. Obesity, smoking, the presence of emotional distress, fibromyalgia and hypothyroidism seem to increase the risk of poor clinical outcomes. A proper selection and/or correction of modifiable prognostic factors could reduce the incidence of endoscopic treatment failure and, as a consequence, improve patient outcomes and quality of life. However, future efforts should focus on experimental and randomised studies to fully determine these associations. [ABSTRACT FROM AUTHOR]

Background: Unacceptably high rates of redislocation, reoperation, osteoarthritis, and coracoid nonunion have been reported in patients with a seizure disorder after surgery for shoulder instabilitiy. Purpose: To evaluate the objective and subjective functional and radiologic results of the arthroscopic Latarjet procedure for anterior shoulder instability in patients with epilepsy and compare them with the results of patients without epilepsy. Study design: Cohort study; Level of evidence, 3. Methods: A retrospective and comparative case-control analysis of patients operated for shoulder instability with arthroscopic Latarjet was conducted. Nineteen patients (21 unstable shoulders) with a seizure disorder (epilepsy group) were matched with 21 patients without a history of seizure (control group). Demographics, surgical indications, and imaging data were collected. Clinical outcomes at a minimum 2 years of follow-up (range, 2-9 years) postoperatively included Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE). The incidence of complications, recurrent instability, redislocation, revision surgery, repeated seizure(s), and presence of osteoarthritis, coracoid nonunion, and osteolysis were also examined. Results: After a mean follow-up of 4.5 years, no significant differences in functional results were found between patients with and without epilepsy on the average Rowe (P =.917), WOSI (P =.621), CMSO (P =.600), and SANE (P =.859) scores. A total of 5 patients (7 shoulders) continued to have seizures postoperatively, but no seizure-related glenohumeral instability was documented. One dislocation and 1 subluxation were documented while participating in sports in each study group, comprising a recurrence rate of 9.5%, but no significant differences were found at comparison (P =.605). A bone defect did not influence the results, as no significant difference was found between the 2 groups. Osteoarthritic changes of the glenohumeral joint were observed in 5 shoulders (23.8%) in the epilepsy group and in 3 (14.3%) in the control group (P =.451). No case of coracoid nonunion or osteolysis was recorded. There was no statistically significant difference in postoperative athletic activity (P =.660). However, patients with epilepsy had significantly lower pre- and postoperative sports participation (P <.001). Conclusion: Arthroscopic Latarjet stabilization can lead to improved functional and subjective outcomes and should be considered in patients with epilepsy with recurrent anterior glenohumeral instability. These results can be achieved regardless of the presence of bone defect and the postoperative control of seizures and are similar to those in patients without epilepsy. [ABSTRACT FROM AUTHOR]

While increased posterior tibial slope (PTS) is an established risk factor for anterior cruciate ligament tears, the association between tibial slope and meniscal posterior root tears is not well-defined.To summarize the available literature evaluating the association between PTS and meniscus root injuries compared with patients without root tears.Systematic review; Level of evidence, 4.A literature search was performed using the Scopus, PubMed, and Embase databases. Human clinical studies evaluating the associations between the medial tibial slope (MTS), lateral tibial slope (LTS), lateral-to-medial (L-to-M) slope asymmetry, and the risk of meniscus root tears were included. Patients with medial meniscus posterior root tears (MMPRTs) and lateral meniscus posterior root tears (LMPRTs) were compared with a control group without root injury. Study quality was assessed using the methodological index for non-randomized studies criteria.Ten studies with 1313 patients were included (884 patients with root tears; 429 controls). The LMPRT subgroup (n = 284) had a significantly greater LTS (mean ± SD, 7.3°± 1.5° vs 5.7°± 3.91°; P < .001), MTS (5.26°± 1.2° vs 4.8°± 1.25°; P < .001), and increased L-to-M asymmetry (2.3°± 1.3° vs 0.65°± 0.5°; P < .001) compared with controls. The MMPRT group (n = 600) had significantly increased MTS relative to controls (8.1°± 2.5° vs 4.3°± 0.7°; P < .001). Furthermore, there was a higher incidence of noncontact injuries (79.3%) and concomitant ramp lesions (56%) reported in patients with LMPRT.Increased MTS, LTS, and L-to-M slope asymmetry are associated with an increased risk of LMPRTs, while increased MTS is associated with MMPRTs. Surgeons should consider how proximal tibial anatomy increases the risk of meniscus root injury. [ABSTRACT FROM AUTHOR]
