Replacement of proximal interphalangeal joints with new ceramic arthroplasty : a prospective series of 20 proximal interphalangeal joint replacements

A prospective consecutive series of 20 proximal interphalangeal ( PIP) joints replaced with a new ceramic unconstrained prosthesis (MOJE) included 13 patients with osteoarthrosis, five with rheumatoid arthritis, and one each with posttraumatic infection and traumatic arthrosis. All patients were assessed preoperatively and postoperatively at one year by an independent physiotherapist and an occupational therapist who evaluated grip strength, range of motion, activities of daily living (ADL) and occupational scores (COPM Canadian Occupational Performance Measure). The mean range of motion of the PIP joint improved from 438 to 608 ( p = 0.001), and the mean grip strength from 169 - 199 N ( p = 0.002). The patients' self-perception of occupational performance, assessed by the COPM, improved significantly from 3.6 - 6.6 (p< 0.001) for satisfaction, and 3.8 - 6.3 (p< 0.001) for performance. The MOJE PIP joint replacement provides significant pain relief, improved strength and range of motion, and short-term satisfaction. Further long-term studies are therefore advocated.
