The primary aim of this study was to describe the long-term patient reported outcomes following surgical repair of acute injuries to the thumb metacarpophalangeal (MCP) joint ulnar collateral ligament (UCL). The secondary aims were to describe the long-term health related quality of life, patient satisfaction and complication rate. From a single surgeon series, 30 patients were identified over an 11 year period (February 2000-February 2011). QuickDASH, EQ-5D-5L, and satisfaction scores were collected from 22 patients (73%) at mean 183 month follow up. The median QuickDASH score was 2.27. Median EQ-5D-5L was 0.88. Satisfaction rate was 82%, Net Promotor Score was 90. Significantly worse QuickDASH scores were seen in patients that developed MCP joint arthrosis or had had subsequent ipsilateral hand injuries (median 39.7 vs 2.27; pā€‰=ā€‰0.002). All the patients employed at the time of surgery returned to work without long-term adaptations. Surgical repair of acute UCL injury generally provides an excellent long-term functional outcome and satisfaction rate. Complications are rare but where MCP joint arthrosis develops functional outcomes can be significantly worse.
