Abstract
BackgroundPatellar tendon rupture is a devastating complication after total knee arthroplasty (TKA). Different strategies have been used to reconstruct or augment direct repairs. MethodsAcute patellar tendon ruptures after TKA were treated using ultra-high molecular weight polyethylene cable (Nesplon cable) for augmentation in four patients. Nesplon cables were inserted anteriorly through the quadriceps just above the patella, and drill holes were placed in the tibial tubercle with one in figure-of-eight fashion and the other in cerclage configuration. Clinical evaluations were performed using range of motion and Knee Society Score at the time of last follow-up. Mean follow-up was 3.5 years. ResultsPostoperatively, mean flexion was 119° and mean extension was 0° in all cases. No knees showed extension lag. Mean knee score was 93.8 and mean function score was 63.8. Infection occurred in one case. ConclusionPatellar tendon reconstruction with Nesplon cable was favorable with good clinical outcomes.
