PURPOSE: To report the outcome of @entity24933 metacarpophalangeal (MCP) joint implants with traumatic nonreconstructible articular cartilage loss. METHODS: We performed a review of all @entity1 at a single institution who underwent a @entity24933 MCP joint arthroplasty performed after an acute injury. Of 820 MCP joint arthroplasties performed, 10 were performed in 7 @entity1 for @entity2720 within 24 hours of the @entity130 . Six were hemi- and 4 were total arthroplasties. The mean follow-up was 4 years. All injuries were the result of a direct laceration over the MCP joint. RESULTS: There were no cases of revision or @entity86 . Mean total arc of motions for the MCP, proximal interphalangeal, and distal interphalangeal joints were 56   (30   to 70  ), 76   (40   to 100  ), and 50   (21   to 70  ), respectively. Postoperative mean grip, oppositional pinch, and appositional pinch strengths were 28, 9, and 11 kg, respectively. All @entity1 except one reported no or mild @entity158 at the last follow-up. Half of the @entity1 required a tenolysis. CONCLUSIONS: MCP joint arthroplasty was performed safely in the setting of acute complex @entity2720 . @entity1 had preservation of adequate @entity2720 and experienced @entity158 . MCP arthroplasty should be a consideration in cases of @entity2720 to preserve motion, prevent @entity158 , and avoid fusion. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
