We report the outcomes of ulnar head replacement with concomitant resurfacing of the sigmoid notch with a lateral meniscal allograft that attempted to recreate the palmar and dorsal radioulnar ligaments in four patients. Patients' ranges of motion, grip strength, postoperative complications and radiographs were assessed. The mean follow-up was 20 (range 12-28) months. There was an increase in postoperative range of motion with an average increase in grip strength of 43% to the unaffected extremity. All patients experienced marked reduction in their postoperative pain. No patients reported symptoms of implant instability. Distal ulna implant arthroplasty with a lateral meniscal allograft gives favourable short-term outcomes. Level of evidence: IV
