Abstract (original English)

Background Prior studies have shown that intra-articular injection of autologous fat may be a viable, less invasive approach for the treatment of carpometacarpal (CMC) joint arthritis, compared with trapeziecetomy. Small joint arthroscopy has also been found to be a useful tool in evaluation and treatment of arthritis. The authors present a treatment for CMC arthritis combining a minimally invasive approach for arthroscopic debridement with autologous fat grafting and platelet-rich plasma (PRP) injection. Methods Patients with Eaton stage II-IV CMC osteoarthritis underwent arthroscopic debridement and injection of autologous fat and PRP into the joint. Pre- and postoperative pain scores, functional outcomes, radiographic improvement in joint subluxation, patient satisfaction, and complications were evaluated. Results Forty-eight thumb CMC joint arthroscopies with fat grafting and PRP were performed. No intraoperative or immediate postoperative complications were experienced. No patients required revision surgery. Average preoperative pain scores with activity improved from 8.9 ± 0.9 to 3.3 ± 2.2 ( P P 1 M 2 overlap was used to measure radiographic subsidence. This improved from 4.4 ± 2.8 mm preoperatively to 6.8 ± 2.3 mm postoperatively, reflecting a relative improvement of 70% ( P Conclusions Treatment of the CMC joint using arthroscopic technique combined with autologous fat
