The Knee

The analysis of the different operative reconstructions of patellar tendon ruptures has not been reported. A critical review of the existing literature was performed to identify the different operative techniques and the post-operative outcomes in acute, chronic and post-total knee arthroplasty (TKA) patellar tendon rupture repairs. ⋯ Acute surgical repair of a patellar tendon rupture using augmented primary repair is associated with the best post-operative outcomes. In chronic and post-TKA repair, autogeneous grafts produce best post-operative outcomes. Immediate post-operative mobilisation should be considered in all repairs. Future papers reporting on patellar operative repairs should have a standardised scoring method of functional outcome to allow more comprehensive comparison and evaluation.
