Anatomic reconstruction of the FCL by an arthroscopically assisted mini-open technique is a viable, less invasive option to treat nonrepairable isolated FCL injury.
Purpose To compare outcomes after arthroscopy in FAIS patients with preoperative asymptomatic gluteal tendinosis (GT) to a control group with no gluteal tendinosis. Methods A retrospective analysis was performed using data from FAIS patients who had arthroscopy between 2016 and 2018. Asymptomatic GT was diagnosed using hip MRI without clinical symptoms. Patients with asymptomatic GT were 1:1 propensity-score matched to patients without GT. Patient-reported outcomes (HOS-ADL, iHOT-12, mHHS), VAS scores, radiographic measures, performed procedures, complications, and revision surgery were compared and analyzed for both groups.Results A total of 105 asymptomatic GT hips and 105 hips without GT were found using propensity-score matching. When compared to preoperative levels, both groups demonstrated significant improvements in PROs and VAS scores at the final follow-up. Besides, there were no significant differences in preoperative scores, final outcome scores, or score improvements between the groups. Patients in the GT group were significantly less likely to achieve the MCID for the VAS score (72.4% vs 83.8%, p = 0.045). However, there were no other differences in the rate of meeting the PASS and MCID between the study and the control groups. Conclusion It was demonstrated in this study that FAIS patients with asymptomatic gluteal tendinosis can expect to experience similar good short-term patients-reported outcomes as compared with patients without gluteal tendinosis. Level of evidence III.
The hip joint is the largest weight‐bearing joint in the body and is surrounded by dense capsules and thick muscles. Hip arthroscopic techniques are suitable for the treatment of hip‐related conditions. These minimally invasive techniques have rapidly developed in China since 2007. Moreover, they have been used in the treatment of gluteal muscle contracture, snapping hip syndrome, femoral acetabular impingement, acetabular labral injury, hip labral calcification, synovial chondroma, osteoid osteoma, synovitis, osteonecrosis of the femoral head, and developmental dysplasia of the hip. This technique has showed its advantage in the total debridement of lesions, precision treatment, and less trauma. However, we lack understanding of the overall development of arthroscopic techniques in China. This review illustrates the recent development of hip arthroscopic techniques in China and related research progress.
Purpose This study aimed to verify the femoral head cartilage protective effect of labral reconstruction in a porcine model. Methods Twelve pigs (24 hips) were divided into 3 groups: labrum defect group, lateral meniscus (LM) allograft group, and LM allograft wrapped with acellular peritoneum matrix (LM-APM) group before undergoing bilateral hip surgery. The pigs were sacrificed at 12 and 24 weeks postoperatively, while the femoral head cartilage was retrieved and then subjected to imaging measurement, macroscopic observations, and biomechanical and histological assessment. Results Imaging measurement and macroscopic observations revealed that the defect area of the labrum was filled in LM and LM-APM allograft groups after 24 weeks, whereas the labrum defect remained at 24 weeks in the control group. The femoral head cartilage corresponding to the area of labral resection in the labral defect group had worse macroscopic Osteoarthritis Research Society International (OARSI) scores, uneven and discontinuous cartilage on hematoxylin and eosin (H&E) staining and Safranin O staining, decreased histopathology OARSI Osteoarthritis Cartilage Histopathology Assessment System (OOCHAS) scores, and decreased elastic modulus and hardness at 12 and 24 weeks after surgery compared with the meniscus allograft groups. Conclusion This study demonstrated that the LM allograft with or without APM for labral reconstruction had a chondroprotective effect on the femoral head in a porcine model.
