Background:
Hip arthroscopy is a common surgical treatment method for femoroacetabular impingement syndrome (FAIS) and typically involves labral repair. Suture limbs can either be placed around (circumferential repair technique) or through (labral base refixation [LBR] technique) the labrum; however, there remains a lack of consensus regarding the superiority of either technique.
Purpose:
To evaluate and narratively synthesize the available evidence on patient-reported outcome measure (PROM) scores of LBR and circumferential repair in patients undergoing hip arthroscopy and labral repair for FAIS.
Study Design:
Systematic review; Level of evidence, 4.
Methods:
A systematic electronic search of MEDLINE, Embase, and the Cochrane Library was carried out on July 21, 2024. All English-language randomized controlled trials, comparative studies, and case series on adults with symptomatic FAIS were eligible for inclusion.
Results:
A total of 12 studies with 1488 patients were included in the analysis. Overall, 9 cohorts with 1035 patients and a mean age of 33.1 years were included in the circumferential repair group, and 6 cohorts with 453 patients and a mean age of 32.3 years were included in the LBR group.Both the circumferential repair and LBR techniques were associated with significant improvements on PROMs, including the mHHS (modified Harris Hip Score), HOS-ADL (Hip Outcome Score-Activities of Daily Living), HOS-SSS (Hip Outcome Score-Sports-Specific Subscale), NAHS (Non-Arthritic Hip Score), WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), and VAS (visual analog scale). Postoperative scores were commonly >80 points across measures, with mean improvements of 20 to 30 points in function and 2 to 4 points in pain. Reported rates of revision surgery and conversion to total hip arthroplasty were low across both techniques, generally <10%, although some variability existed between studies.
Conclusion:
Both techniques led to improved PROM scores after hip arthroscopy for the management of FAIS. Given the heterogeneity and predominance of lower level evidence, future high-quality comparative studies are warranted.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
