Abstract:

Background: Patellar crepitus after total knee arthroplasty (TKA) is not uncommon. The choice between patellarresurfacing or retention in TKA has remained controversial. Therefore, this randomized controlled trial aimed to evaluatethe impact of patellar resurfacing on the incidence of patellar crepitus. In addition, we compared the clinical outcomesand satisfaction between the patients who underwent patellar retention or resurfacing.Methods: A total of 63 patients randomly received patellar resurfacing or non-resurfacing TKA by one surgeon at ImamKhomeini Hospital Complex, Tehran University of Medical Sciences, Iran during May 2014-February 2017. Finally,29 patients in the resurfaced group and 44 subjects with retained patella were evaluated pre-op and in an averagefollow-up period of 8.68 months using the clinical Knee Society Score (KSS), functional KSS, and Knee injury andOsteoarthritis Outcome Score (KOOS).Results: Our findings demonstrated no significant difference between the two groups regarding the satisfactionof patients, KSS, and KOOS. It was shown that the latter scores improved in both groups in the follow-up period.Nonetheless, patellar crepitus was not statistically different between the two groups.Conclusion: According to the results of the present study, patellar resurfacing did not lead to decreased patellarcrepitus or enhanced clinical outcomes of TKA.Level of evidence: I

Comparison of Clinical Results between Patellar Resurfacing and Non-resurfacing in Total Knee Arthroplasty: A Short Term Evaluation

Background: There is no difference in the functional outcomes 6 months after total knee arthroplasty (TKA) for kneeosteoarthritis between patellar resurfacing and non-resurfacing. Thus, we have performed this study to compare theshort-term clinical outcomes of TKA performed with and without the patella resurfacing.Methods: A total of 50 patients with osteoarthritis of the knee (OAK) were random...

Patellar resurfacing versus retention in total knee arthroplasty.

We studied 40 patients in whom the patella was not severely deformed and who were undergoing primary total knee arthroplasty (TKA) for osteoarthritis by one surgeon using one type of prosthesis. They were randomly allocated either to have the patella retained or resurfaced with a cemented, all-polyethylene component regardless of the state of the patellar articular cartilage. Apart from removal...

Patellar resurfacing or retention in total knee arthroplasty. A prospective study of patients with bilateral replacements.

Patellofemoral problems are a common cause of morbidity and reoperation after total knee arthroplasty. We made a prospective study of 52 patients who had bilateral arthroplasty (104 knees) and in whom the patella was resurfaced on one side and not on the other. A movable-bearing prosthesis with an anatomical femoral groove was implanted on both sides by the same surgeon using an otherwise ident...
