From: Results of total knee arthroplasty for painless, stiff knees
A 31-year-old male patient who had a history of arthrodesis due to tuberculosis infection of the left knee at the age of 17 years. His right knee was ankylosed in 15º of flexion. Take down and total knee arthroplasty (TKA) with a valgus-varus constrained (VVC) prosthesis (Nexgen LCCK) were performed. At 51 months after the key operation, the polyethylene insert was dislocated with breakage of the locking screws after sea-swimming. After exchanging the polyethylene insert with a posterior-stabilized (PS) type, no further complications occurred, with an arc of motion of 0–130º.
