Mid‐ to Long‐Term Follow‐Up Outcomes of Single Design Rotating Hinge Knee in Infected and Noninfected Revision Patients

Total knee arthroplasty (TKA) offers significant relief for advanced knee osteoarthritis. With an aging population, TKA procedures are increasing, leading to a higher demand for revision surgeries. Rotating‐hinge knee (RHK) prostheses have emerged as a solution for complex revisions, but the long‐term durability of RHK prostheses and their effectiveness in infection‐related revisions remain controversial. Therefore, this study aimed to evaluate the mid‐ to long‐term clinical and survivorship outcomes of a single‐design rotating hinge knee (SDRHK) system in revision TKA, comparing patients revised for infection with those revised for noninfectious causes.
