Incidence of Total Knee Arthroplasty After Arthroscopic Surgery for Knee Osteoarthritis .
Incidence of Total Knee Arthroplasty After Arthroscopic Surgery for Knee Osteoarthritis: A Secondary Analysis of a Randomized Clinical Trial.
JAMA Netw Open . 2024 Apr 1;7(4):e246578. doi: 10.1001/jamanetworkopen.2024.6578.One hundred seventy-eight patients with knee osteoarthritis were randomized to receive arthroscopic surgery plus nonoperative management (n=92) or nonoperative management alone (n=86). The primary outcome of interest was the incidence of total knee arthroplasty (TKA) on the affected knee. Secondary outcomes included TKA or high tibial osteotomy on either knee. Outcomes were assessed up to a median of 13.8 years. Overall, the results showed no significant difference in TKA incidence between groups. Findings suggest that adding arthroscopic surgery to nonoperative care did not delay or hasten the need for TKA.
