Total knee arthroplasty for ankylosed knees in the extended position with hemophilia: a medium- and long-term single-center experience.

ABSTRACT:

Background

Total knee arthroplasty (TKA) is one of the curative methods for patients with end-stage ankylosed knees. However, the existing methods are difficult to enable patients with hemophilic ankylosed knees to recover good functional activities.

Methods

Between January 2008 and December 2021, 22 male patients with ankylosed knees in the extended position due to hemophilia underwent TKA. The average age of the patients was 41.3 years (range, 19 to 52 years), and the average hospital stay was 33.4 days (range, 14 to 50 days). TKA was performed using quadriceps tendon Z-lengthening plasty, staged osteotomy, and comprehensive soft-tissue release. A variety of methods were used to evaluate the postoperative clinical outcomes and complications, including range of motion (ROM)
