Patellar Resurfacing in Primary Total Knee Replacement

Abstract

Patients who underwent patellar resurfacing experienced anterior knee pain and satisfaction with the arthroplasty procedure that were equivalent to those experienced by patients whose patella was not resurfaced; however, these patients underwent significantly fewer additional surgical procedures. Further long-term follow-up of modern prostheses in randomized studies measuring outcome with a patella-specific score is needed.

Common controversies in total knee replacement surgery: Current evidence

“…Beaupre et al [43] in 2012, performed a randomized controlled trial, with a follow-up of 5-10 years, in which they agreed that patellar resurfacing showed no difference with non-resurfacing regarding knee specific outcomes, like pain, stiffness, and function. Also in 2012, Pilling et al [44] in a meta-analysis of randomized controlled trials, highlighted the advantages of this method in the field of preventing additional surgical procedures and patella-femoral complications, but, nevertheless, reported no difference in operative time, infection rate, radiographic appearance, patient satisfaction, and anterior knee pain.…”

International Comparative Evaluation of Fixed-Bearing Non-Posterior-Stabilized and Posterior-Stabilized Total Knee Replacements

“…Abdel et al reported that at fifteen years the non-posterior-stabilized knee replacements performed slightly better in the knees with deformities than in those without deformities and that the opposite was true for posterior-stabilized knee replacements, which performed better in the knees without deformities 11 . The role of patellar resurfacing in total knee arthroplasty has been investigated, often with contradictory results [27][28][29][30][31][32] . The results of our study indicate that the revision risk for posteriorstabilized knees is double that for non-posterior-stabilized knees in cases with nonresurfaced patellas.…”

“…Some registries contained relatively few posterior-stabilized procedures. Significant differences in the rates of patellar resurfacing existed between registries and had a major effect on survival [29][30][31][32] . Some registries within the group are larger than others, with different follow-up intervals, and therefore might have had a greater influence on the results.…”

Does patellofemoral congruence following total knee arthroplasty correlate with pain or function? Intraoperative arthroscopic assessment of 30 cases

“…Despite its success, many patients remain dissatisfied after TKA, where patellofemoral pain and instability remain among the most common reasons for reoperation or revision (3)(4)(5)(6)(7).…”
