Teel AJ, et al. - Given the controversies regarding the management of the patella during total knee arthroplasty (TKA), researchers appraised the evidence regarding the use of patellar resurfacing in TKA. A meta-analysis of 20 eligible RCTs was performed. Statistically significant differences were observed between knees receiving patellar resurfacing vs those not receiving resurfacing during primary TKA, that favored the resurfaced group in the knee component and functional component of Knee Society Scores, however, these were not clinically significant. Outcomes suggest a higher likelihood of undergoing reoperation, most often for secondary resurfacing, in knees that do not receive patellar resurfacing. However, no clear findings were gained regarding the disease burden of differing complication profiles associated with resurfacing and nonresurfacing groups.
