Core Tip

Core Tip: Knee osteoarthritis (KOA) with extra-articular deformities is a common disease, but the choice of surgical methods has always been controversial. The use of total knee arthroplasty alone to achieve the purpose of extra-articular osteotomy and treatment of KOA at the same stage has been rarely reported in the literature. After the operation, the varus deformity was well corrected and the force lines of lower extremities were basically aligned. The follow-up results showed that the prosthesis was firmly fixed and the unstable walking function was significantly improved. This method provides a feasible choice for the surgical treatment of KOA with extra-articular deformity.
