FUNCTIONAL OUTCOMES OF HIP ARTHROSCOPY IN AN ACTIVE DUTY MILITARY POPULATION UTILIZING A CRITERION-BASED EARLY WEIGHT BEARING PROGRESSION.

INTRODUCTION: Hip arthroscopy allows surgeons to address intra-articular pathology of the hip while avoiding more invasive open surgical dislocation. However the post-operative rehabilitation protocols have varied greatly in the literature, with many having prolonged periods of limited motion and weight bearing. PURPOSE: The purpose of this study was to describe a criterion-based early weight bearing protocol following hip arthroscopy and investigate functional outcomes in the subjects who were active duty military. METHODS: Active duty personnel undergoing hip arthroscopy for symptomatic femoroacetabular impingement were prospectively assessed in a controlled environment for the ability to incorporate early postoperative weight-bearing with the following criteria: no increased pain complaint with weight bearing and normalized gait pattern. Modified Harris Hip (HHS) and Hip Outcome score (HOS) were performed preoperatively and at six months post-op. Participants were progressed with a standard hip arthroscopy protocol. Hip flexion was limited to not exceed 90 degrees for the first three weeks post-op, with progression back to running beginning at three months. Final discharge was dependent upon the ability to run two miles at military specified pace and do a single leg broad jump within six inches of the contralateral leg without an increase in pain. RESULTS: Eleven participants met inclusion criteria over the study period. Crutch use was discontinued at an average of five days following surgery based on established weight bearing criteria. Only one participant required continued crutch use at 15 days. Participants' functional outcome was improved postoperatively, as demonstrated by significant increases in HOS and HHS. At the six month follow up, eight of 11 participants were able to take and complete a full Army Physical Fitness Test. CONCLUSIONS: Following completion of the early weight bearing rehabilitation protocol, 81% of participants were able to progress to full weight bearing by four days post-operative, with normalized pain-free gait patterns. Active duty personnel utilizing an early weight bearing protocol following hip arthroscopy demonstrated significant functional improvement at six months. LEVEL OF EVIDENCE: Level 4, Case-series.

Outcomes of biceps tenodesis in an active duty population.

Pathology affecting the long head of the biceps tendon and its insertion is a frequent cause of shoulder pain in the active duty military population. The purpose of this investigation was to evaluate functional outcomes of subpectoral biceps tenodesis in an active duty population. A retrospective case series of 22 service members who underwent biceps tenodesis was performed and Shoulder Pain and Disability Indexes (SPADI) and Disabilities of the Arm, Shoulder and Hand (DASH) scores were obtained preoperatively and at 6 months. Additionally, a review of each subject's physical profile was performed 6 months after surgery to determine continued physical limitations and one's ability to deploy. There was a statistically significant improvement in SPADI and DASH scores comparing preoperative versus postoperative outcomes. Although five subjects (22%) continued to have a restriction to performing push-ups on the Army Physical Fitness Test, all were deemed deployable from a physical standpoint. The results of this review suggest that active duty personnel undergoing biceps tenodesis have significant functional improvement at 6 months. Additionally, very few have long-term physical limitations or deployment restrictions.

A criterion based sling weaning progression (sweap) and outcomes following shoulder arthroscopic surgery in an active duty military population.

INTRODUCTION: Little objective evidence is available to guide rehabilitation protocols in regard to the sling weaning process following arthroscopy surgery of the shoulder. The purpose of this study was to establish an objective, criterion based protocol for accelerated sling weaning following shoulder arthroscopy. METHODS: 82 active duty service members (ADSM) underwent elective shoulder arthroscopic surgery by three orthopaedic staff surgeons. One physical therapist progressed patients through the criterion based sling weaning progression (SWEAP) protocol for each surgery and documented pain levels, sleep habits, and decrease in sling use. Preoperative and six month postoperative Quick Disability of the Arm, Shoulder, and Hand (qDASH) and Shoulder Pain and Disability Index (SPADI) scores were obtained. The ability to perform an Army Physical Fitness Test (APFT) was recorded at six months postoperative. RESULTS: Patients completed sling weaning at an overall mean of 16.6 ± 5.0 days with continued use in unprotected military settings only beyond this timeframe. As patients steadily progressed out of the sling for 1 hour, 2-3 hours, and half-day periods, average pain scores decreased during these time periods at 5.0±1.2, 3.7±1.2, and 2.1±1.3 (0-10 pain scale), respectively. Patients obtained 6-7 hours of sleep or normal sleep habits at an average of 10.9±4.4 days postoperative. Overall, preoperative qDASH and SPADI scores improved from 39.8±13.0 to 2.4±2.0 and 46.4±16.1 to 3.3±3.2, respectively, at 6 months follow up. All 82 patients were able to return to deployable status. 30 (36.6%) patients required formal restrictions for the push-up portion of the APFT at six months postoperative. 7 of these 30 patients required running restrictions. CONCLUSIONS: Early improvement in quality of life indicators can be obtained in the initial postoperative period with a progressive, criterion based SWEAP protocol. Patients demonstrated favorable outcomes with return to occupational and physical fitness activities. This study will guide orthopedic surgeons and physical therapists to enhance the sling weaning process during rehabilitation protocols and improve preoperative counseling sessions for accurate postoperative expectations.
