Podium Presentation Title: Outcomes After Quadriceps Tendon Repair: Transosseous Tunnel vs. Suture Anchor Techniques

Recent biomechanical studies have compared traditional transosseous (TO) quadriceps tendon repairs to newer techniques for suture anchor (SA) repair. However, clinical comparing the two are limited. The purpose of this study was compare failure rates and patient reported outcomes between TO SA repairs. Following IRB approval, patients who underwent primary repair rupture with tunnel or January 2009 August 2018 were identified from a prospectively maintained institutional database retrospectively reviewed. Patients contacted by email telephone interview satisfaction (1-10 scale), current function (1-100 (retear), revision surgeries; International Knee Documentation Committee score (IKDC), Injury Osteoarthritis Outcomes Score (KOOS), Lysholm questionnaire also collected. Seventy (92.1%) available phone at mean 4.64±2.53 years postoperatively (transosseus sutures: 34 anchor: 42). Out these 70 patients, there 10 failures an overall rate 14.29%. Failure not significantly different treatment groups (TO: 5/34, 14.71% vs SA: 5/42, 11.90%, p=.622) (Figure 1). in each group had similar ratings (SA: 9.17±1.95 TO: 8.31±2.30, p=.102). higher subjective 89.08±8.40 76.14±23.52, p=.003) greater final IKDC scores (72.30 ± 22.08 56.80 16.62; p=.041). In conclusion, is no significant difference transosseus ruptures follow-up. Most occur secondary traumatic reinjury within first year post-operatively. IKDC, KOOS Pain, Quality Life scores.
