- Abstract
This study was performed to assess the clinical and radiographic results at a minimum of 2 years after ligament reconstruction suspension arthroplasty (LRSA) that comprised full trapeziectomy and suspensionplasty using the palmaris longus tendon and the Mini TightRope (Arthrex, Naples, FL) for advanced thumb carpometacarpal arthritis. We clinically and radiographically evaluated 26 thumbs in 26 patients who had undergone LRSA at least 2 years previously. The mean follow-up period was 35.9 months. We evaluated the subjective clinical outcomes (visual analogue scale and Quick Disabilities of the Arm, Shoulder, and Hand scores) and objective clinical outcomes (range of motion, pinch strength, grip strength, and trapezial space height ratio). At the final follow-up evaluation, the mean visual analogue scale score was 11.1 (standard deviation (SD) 13.4) and the mean Quick Disabilities of the Arm, Shoulder, and Hand questionnaire score was 9.39 (SD 10.1). The mean palmar and radial abduction were 62.3° (SD 11.8°) and 63.8° (SD 9.09°), respectively. The mean key pinch and grip strength were 3.92 (SD 1.07) kg and 19.7 (SD 7.77) kg, respectively. The mean trapezial space ratio was 0.21 (SD 0.10). The subjective clinical outcomes, range of motion, and pinch strength were significantly improved compared with preoperatively. LRSA for advanced-stage thumb carpometacarpal osteoarthritis relieves pain, improves range of motion and strength, and obtains favourable subjective patient-reported clinical outcomes.
