Sekundaarinen patellapinnoitus polven tekonivelleikkauksen jälkeen – 101 potilaan tulokset Tekonivelsairaala Coxasta

Abstract

Secondary patellar resurfacing (SPR) is a procedure which can be used with patients suffering from persistent anterior knee pain after total knee arthroplasty (TKA). In this retrospective study our aim was to examine the effectiveness of SPR in alleviating anterior knee pain after TKA. We examined 101 patients who had undergone SPR at our institution between 2009 and 2016. Their medical records were reviewed for overall satisfaction after procedure, range of knee motion and pain improvement after SPR. Persistent pain after TKA was the prominent indication for the procedure in 61.4 % of the cases, and 72.3 % of these patients had anterior knee pain. 47.5 % of all of the patients were fully satisfied with the outcome of SPR and additional 19.8 % described their state as better than before the procedure. However, 30.7 % of the patients were not satisfied and still suffered from anterior knee pain and other symptoms after SPR. Although most patients described their postoperative state as better than before SPR, only 38.6 % of them had no symptoms after the procedure and 60.4 % were left with some residual symptoms such as pain or stiffness. Further research is needed to identify those patients who are most likely to benefit from SPR.
