Fatigue fracture of the hinge pin in a semi-constrained total knee arthroplasty: a case report
Abstract
Material failure is a rare complication in total knee arthroplasty (TKA). This case report shows a fatigue fracture of the hinge pin as a consequence of a postoperative persisting valgus deviation in a semi-constrained TKA.
