Objective: Pelvic compensation is common in femoroacetabular impingement (FAI) patients to reduce symptoms and increase range of motion. However, little attention was given to the postoperative clinical effect of pelvic compensation. Therefore, this study aims to compare the outcomes between pelvic compensation and normal pelvic position in femoroacetabular impingement (FAI) patients after hip arthroscopy. Methods: The retrospective study was conducted from January 2019 to June 2022, recruited consecutive patients who were diagnosed with FAI and received subsequent arthroscopic treatment. All patients completed an X‐ray in the anterior–posterior standing position before and 4 weeks after surgery. Patients with pelvic compensation were compared with those who did not. Functional outcomes included hip disability and osteoarthritis outcome score (HOOS), modified Harris (mHHS) score, and lower‐extremity activity scale (LEAS). Secondary outcomes included the EuroQol Five Dimensions Questionnaire (EQ‐5D) and patient satisfaction. The intraclass correlation coefficient (ICC) was used to analyze interobserver and intraobserver reliability. Results: Ninety patients with a mean age of 39.40 years were included in the study. No significant compensation changes were noted within groups after the elimination of impingement. The functional scores showed no significant difference between groups (p(HOOS) = 0.352, p(mHHS) = 0.183, p(LEAS) = 0.865). The EQ‐5D revealed statistically better performance in usual activities in the compensatory group (p = 0.044). There are no significant between‐group differences in patients' satisfaction evaluations. Conclusion: As assessed by Patient‐Reported Outcome Measures (PROMs), patients with compensatory pelvic tilt demonstrated similar clinical outcomes without extra adverse events to patients with normal pelvic positioning in short‐term follow‐ups. Furthermore, compensatory pelvic tilt did not significantly enhance the range of motion or functional outcome at short‐term follow‐ups. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this protocol was to discover the connection between patients with non-surgical pain or other discomfort and their psychosocial status. Cognitive behavior therapy will be used, which we verified will determine the effect and feasibility of postoperative rehabilitation processes. Materials and Methods: This study will include 200 patients ranging from 18 to 60 years old who have underwent or will undergo FAI arthroscopy in the West China Hospital Sports Medicine Center from 2023 to 2026. A standardized prospective single-center parallel-group randomized controlled trial will be used for these participants. The participants will be divided into intervention (telephone versus face-to-face versus music versus floatation) and control groups. The follow-up periods will be measured pre-operatively, as well as postoperatively at 1, 3, and 6 months. The primary outcomes will include the modified Harris Hip Score (mHHS) and the Visual Analogic Score (VAS), and the secondary outcomes will include the range of motion (ROM), the Huaxi Emotional-distress Index (HEI), and the depression, anxiety, and stress scale (DASS-21 scale). Furthermore, the Patient Health Questionnaire-9 (PHQ-9) and a Short-Form 12 (SF-12) questionnaire will also be evaluated. Discussion: This study will evaluate the clinical and cost-effectiveness of different types of psychosocial-therapy-based rehabilitation methods designed to improve the quality of life of FAI patients with persistent symptoms.

Background: Knee arthroscopic arthrolysis serves as an effective treatment for knee arthrofibrosis. However, hemarthrosis is the most common complication in arthroscopic surgery, which has potential adverse effects on postoperative rehabilitation. The purpose of this study was to evaluate the effects of topical tranexamic acid (TXA) in knee arthroscopic arthrolysis. Methods: A total of 87 patients with knee arthrofibrosis who underwent arthroscopic arthrolysis from September 2019 to June 2021 were eligible for this retrospective review. Patients in the TXA group (n = 47) received topical administration of TXA (50 mL, 10 mg/mL) at the end of the surgery, and patients in the control group (n = 40) received no TXA. The postoperative drainage volumes, hematologic levels, inflammatory marker levels, knee range of motion (ROM), visual analog scale (VAS) pain scores, Lysholm knee scores and complications were compared between the two groups. The curative effect of each group was calculated according to Judet's criteria. Results: The mean drainage volumes on postoperative day (POD) 1 and POD 2, and total drainage volume were significantly lower in the TXA group than in the control group (P < 0.001 for all). The TXA group had significantly lower postoperative CRP and IL-6 levels on POD 1 and POD 2, and at postoperative week (POW) 1 and POW 2 than the control group. The VAS pain scores in the TXA group were significantly lower on POD 1 and POD 2, and at POW 1 and POW 2 than those in the control group (P < 0.001 for all). Patients in the TXA group showed better postoperative ROM and Lysholm knee scores at POW 1 and POW 2. No patient had any complications such as deep venous thrombosis (DVT) or infection. The excellent and good rates of knee arthroscopic arthrolysis were comparable between the two groups at the sixth postoperative month (P = 0.536). Conclusions: Topical administration of TXA in knee arthroscopic arthrolysis can reduce postoperative blood loss and inflammatory response, alleviate early postoperative pain, increase early postoperative knee ROM, and improve early postoperative knee function without increased risks.

Objective: To explore the development of hip arthroscopy in China through reviewing the change of the application of hip arthroscopy operation on treating femoracetabular impingement (FAI). Method: Papers were retrieved from January 1, 2005 to November 1, 2019, from databases CNKI, Wanfang Data, VIP, PubMed, and Embase. The keywords are Hip Impingement, Femoroacetabular impingement, Hip arthroscopy, Arthroscopic operation, Hip Arthroscopy operation, and Arthroscope, etc. The quality of papers was assessed through MINORS , and statistics and meta‐analysis were performed by Word, Excel, and Revman 5.3 Zurich, Switzerland. Results: From a total of 8,953 papers, 46 review articles without data and 48 articles with data were involved, and 25 papers were included in the Meta‐analysis. The twenty‐five papers were selected from 48 papers with data, of which 41 were reported in Chinese, 11 were missing complete Harris scores, five did not mention the number of patients who had lost follow‐up, three had minors quality scores below 7, one did not have enough FAI cases, and three did not have standard deviations in Harris scores. Overall, in China, the application of hip arthroscopy regarding FAI has flourished while maintaining a high level of treatment and has reached its peak in the past 2 years. Conclusion: With the rapid development of hip arthroscopy in China, hip operation is widely recognized, many reports on its application on FAI have emerged successively, and the scope of application and technical level have been improved.

Objectives: Parameniscal cysts can be removed without meniscectomy, but for large or multiloculated meniscal cysts, traditional arthroscopic excision may leave the meniscus unstable. This study aimed to describe a modified fat pad approach for parameniscal cyst arthroscopic excision that retains a stable structure of the synovial margin of the meniscus and to compare the clinical outcomes between the traditional cyst excision and modified excision techniques. Methods: Fifty‐six patients with parameniscal cysts between 2014 and 2018 were retrospectively included in this study with 28 patients in each group. All patients underwent arthroscopic parameniscal cyst excisions with traditional and modified excision techniques respectively in each group. The International Knee Documentation Committee subjective (IKDC) score, Lysholm score, visual analogue scale (VAS) score, Tegner score, active range of motion (ROM) and time to recover full ROM were used to evaluate the clinical outcomes by using the t‐test. Results: The patient population included 21 males and 35 females, with a mean follow‐up of 29 months. Of these, 28 patients underwent traditional arthroscopic cyst excisions and meniscal sutures, and 28 patients underwent arthroscopic excisions by the modified fat pad approach. There were no significant differences in the IKDC score, Lysholm score, Tegner score or VAS score between the traditional and modified excision groups at the final follow‐up time point. However, the postoperative time to recover full ROM in the modified excision group was significantly lower than those in the traditional excision group (p < 0.05). Conclusion: Arthroscopic excision with the modified fat pad approach yielded a shorter pain phase and less time to recover full ROM during recovery compared with the traditional arthroscopic excision. The new method seemed to be effective, as evidenced by the positive clinical outcomes of patients. [ABSTRACT FROM AUTHOR]

Background: Bone bruise (BB) and kissing contusion are common features of acute anterior cruciate ligament (ACL) injury on magnetic resonance imaging (MRI). The correlation between the location and distance of kissing contusions and knee laxity remains unclear. Purpose: To determine the significance of different patterns of BB in acute noncontact ACL injury and assess the correlation between the location and distance of kissing contusions and the severity of knee laxity. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 205 patients with acute noncontact ACL injury undergoing arthroscopic treatment between January 2021 and May 2022 were included in this retrospective analysis. Patients were grouped according to the different patterns of BB. The type of ACL injury and concomitant injuries were analyzed on MRI and confirmed by arthroscopy. Anterior knee laxity was assessed by the Ligs digital arthrometer and stress radiography, and rotational knee laxity was assessed by the intraoperative pivot-shift test. The MRI parameters of the location and distance of kissing contusions were measured to assess their correlations with the severity of knee laxity. Results: Of the 205 patients with acute noncontact ACL injury, 38 were in the non-BB group and 167 were in the BB group, the latter including 32 with the isolated BB on the lateral tibial plateau and 135 with kissing contusions. There was no significant difference in the mean time from initial injury to MRI scan between the non-BB group and the BB group (14.34 ± 2.92 vs 15.17 ± 2.86 days; P =.109) or between the isolated BB subgroup and the kissing contusion subgroup (14.94 ± 2.92 vs 15.23 ± 2.85 days; P =.605). The side-to-side difference (SSD) in anterior knee laxity and the incidences of complete ACL injury, concomitant injuries, and high-grade pivot-shift test were significantly higher in the BB group than in the non-BB group, and in the kissing contusion subgroup compared with the isolated BB subgroup. The kissing contusion index of the lateral femoral condyle (LFC) and the sagittal distance of kissing contusions were significantly correlated with the SSD in anterior knee laxity and the grade of pivot-shift test (P <.001). Conclusion: The presence of BB, in particular the appearance of kissing contusions, was related to greater knee laxity and higher incidences of complete ACL injury and concomitant injuries in acute noncontact ACL injury. For patients with kissing contusions, as the location of BB on the LFC moved forward and the distance between kissing contusions increased, anterior and rotational knee laxity became more serious.
