Delayed Repair with Augmentation using Achilles Allograft of Old Ruptured Patellar Tendon after Revison Total Knee Arthroplasty: A Case Report / 대한정형외과학회잡지

ABSTRACT

The rupture of the patellar tendon after total knee arthroplasty (TKA) is rare but serious complication resulting in a severe dysfunction in the extension mechanism. There are a few reports on the treatment of this condition. However, there is still some controversy regarding the choice of proper management. There is no report of the patellar tendon augmentation or reconstruction in this condition in the Korean literature. We report a case of an old patellar tendon rupture in 70-year old patient that occurred at 5 months after a two stage revision for an infected TKA and was treated satisfactorily by delayed repair with augmentation using an Achilles allograft.
