EP268 Arthroscopic and Open Postoperative Hip Capsular Deficiency Management Strategies – A Scoping Review
Bibliographic record
Abstract
Abstract Purpose of Review This scoping review aimed to identify the indications, techniques, outcomes, and knowledge gaps related to managing postoperative native hip instability. Specifically, it examined how capsular repair and reconstruction strategies address iatrogenic capsular insufficiency following hip preservation procedures, with the goal of clarifying optimal surgical decision-making and guiding future research. Recent Findings Arthroscopic reconstruction emerged as the most commonly described technique for post-arthroscopic hip instability, frequently involving the use of dermal allografts, iliotibial band, or Achilles tendon grafts. Arthroscopic repair methods (i.e., capsular plication) were also widely reported, showing improved patient-reported outcomes in case series and retrospective cohorts. Open reconstruction and repair approaches were less common but demonstrated comparable potential for restoring hip stability in select patients. Postoperative protocols emphasized restricted weight-bearing, bracing, and controlled rehabilitation to prevent excessive capsular strain. Despite promising clinical improvements, published data were predominantly case reports, technical notes, and small retrospective studies. Summary Instability should be carefully considered and properly assessed in patients experiencing persistent pain and sensations of abnormal hip “looseness” or locking following hip arthroscopy. Capsular repair and reconstruction are viable interventions for addressing hip capsular deficiency and alleviating symptoms of iatrogenic instability. In the absence of high-quality comparative trials, no definitive consensus exists on optimal graft selection or surgical technique, although dermal allografts and iliotibial band constructs have both shown positive outcomes. Larger, prospective and/or comparative studies are needed to refine patient selection, establish standardized protocols, and evaluate long-term efficacy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
