Thiengwittayaporn S, Sumranwanich N, Hongku N, et al. - This study sought to correlate the patellar crepitus (PC) complication between an inlay and onlay patellar resurfacing techniques in a prospective, randomized controlled trial. Researchers randomized a sum of 222 patients who had undergone unilateral total knee arthroplasty (TKA) using a Legion posterior-stabilized (PS) total knee system into the two groups. They assessed PC incidence, time of PC presentation, radiographic parameters correlated with PC development, and clinical outcomes at 3, 6, 9, 12, 18, and 24 months postoperatively. They imply an inlay patellar resurfacing technique during PS-TKA with this knee system to decrease the chance of PC development.
