PURPOSE: To evaluate the clinical and functional outcome following the reconstruction of chronic @entity397 using the contralateral bone-tendon-bone (BTB) autograft. METHODS: The records of seven @entity1 who underwent reconstruction of chronic @entity397 with contralateral patellar BTB were retrospectively reviewed. Chronic tears were defined as a minimum of 3  months from injury to initial clinical evaluation. Clinical assessments included range of motion of the knee, Tegner, Lysholm and International Knee Documentation Committee (IKDC) score and a radiographic analysis of patellar height (Caton-Deschamps index). @entity260 and @entity121 strength at last follow-up were reported. RESULTS: The mean age of the @entity1 undergoing surgery was 33 (  10.5) years with a mean follow-up of 41.3 (  29.7) months. Reconstruction surgery was performed at an average of 16  months (3-60  months) after the injury. 86  % of the @entity1 had a normal patella height with mean of patellar height of 1.5 (  0.2) in preoperative radiographs and of 1.2 (  0.07) on postoperative evaluation (p  =  0.0136). The mean IKDC was 45.5 (  10.8) before surgery and 64.5 (  12.4) at the last follow-up (p  =  0.0001), and Lysholm score was 45.4 (  11.3) and 79 (  11.8), respectively (p  =  0.0001). The median Tegner activity scale preinjury was 6 (range 5-7), preoperatively was 1 (range 1-2) and 4 (range 2-5) postoperatively (p  =  0.0001). All @entity1 had @entity121 wasting with a difference in thigh girth between the injured side and healthy side of 3.6      0.7  cm (ns). No surgical complications were encountered. CONCLUSIONS: In this limited cohort, surgical reconstruction of chronic @entity397 using contralateral bone-tendon-bone graft was a safe and viable option that improves clinical and functional outcomes compared to presurgical function. However, despite the restoration of a normal patellar height, function did not return to preinjury level.
