Purpose: To examine the outcomes of arthroscopic treatment of the hip in a young, active military population. Specifically, the ability to return to duty was the prime indicator of success. In addition, an objective evaluation of various demographic and surgery-related variables was performed to identify predictors for success or failure of treatment in this military population.

Methods: A retrospective chart review was undertaken to ascertain the results of hip arthroscopy at a single academic military medical center. A total of 206 patients underwent 223 hip arthroscopies during a 13-year period (2000-2013). Of these, 159 patients met the inclusion criteria, which included active duty military service and at least 12-month follow-up. Veterans Affairs Beneficiaries, active duty dependents, and those with less than 12 months of follow-up were excluded. Surgeries were performed by 1 of 5 fellowship-trained orthopaedic surgeons. Data were collected from the Armed Forces Health Longitudinal Technology Application, Electronic profiling system, and Physical Evaluation Board.

Results: A total of 159 patients were available for the study, 102 males and 57 females. The average age of the patients overall was 30.9 ± 8.3 years (range, 18-52 years). Junior enlisted, which is considered entry level, made up 64.2% of the subjects. The most common diagnosis was femoroacetabular impingement, and the most common procedure performed was acetabuloplasty. Twenty-two percent of patients underwent evaluation by the medical retention board after hip arthroscopy and were separated from military service. Seventy-eight percent of soldiers were maintained on active duty after hip arthroscopy. The overall complication rate was 15.7%, with a major complication rate of 1.25% defined as femoral neck fracture, abdominal compartment syndrome, osteonecrosis, deep vein thrombosis and/or pulmonary embolus, and septic arthritis. Univariate analysis of risk factors showed the presence of a complication to be a significant predictor for failure to return to active duty (odds ratio [OR] 4.04, P = .0035) as was senior noncommissioned officer rank (OR 0.20, P = .0347). Multivariate analysis showed only the presence of a complication to be a significant predictor for failure to return to active duty (OR 3.71, P = .0083).

Conclusions: Hip arthroscopy in a military population is effective in treating multiple causes and retaining soldiers on active duty status. Complications of any kind from surgery or postoperatively are significant predictors of medical separation and may warrant earlier initiation of a medical evaluation board.

Level of evidence: Level IV, therapeutic case series.
