Patellar Resurfacing in Total Knee Arthroplasty Leads to Better Isokinetic Performance and Higher Clinical Scores

Not Applicable

Completed

• Conditions: Knee Osteoarthritis
• Interventions: Device: patellar component

• Registration Number: NCT04637490
• Lead Sponsor: Gulhane Training and Research Hospital

Brief Summary

For decades there have been concerns about patellar resurfacing (PR) in total knee arthroplasty (TKA) and the individual preference of the surgeon is still the main determinant of whether or not resurfacing is applied. According to preference, surgeons can be categorized in 3 main groups of those who usually, selectively or rarely resurface. The aim of this prospective, randomized, controlled study to is compare the isokinetic performance and clinical outcome of TKAs with PR and without PR.

Detailed Description

Patients undergoing TKA for primary osteoarthritis of the knee are randomly assigned to either the PR or non-PR groups. The differences between groups with respect to age, BMI, gender, and preoperative Knee Society Score (KSS), and isokinetic performance are evaluated. Patients are evaluated at postoperative 3, 6, and 12 months with KSS and at 6 months and 1 year with isokinetic measurements.
