Abstract: Objective To investigate the clinical effect of replantation of the remaining part of articular cartilage treating partial interphalangeal cartilage defect. Methods From 2010 June to 2019 August, 16 cases （16 interphalangeal joints） with partial articular cartilage defects, were reviewed and analyzed. And then, 5 were proximal interphalangeal joints and 11 were distal interphalangeal joints. All cases were treated by removing the retained cartilage （the proportion reached at least half the articular facet） and then replanting it. After the surgeries, the stability, the appearance, the joint function were evaluated. Results 16 patients were followed 12 to 60 months （mean 36 months）. No cartilage necrosis was found. The lateral angulation deformities were corrected. The stiffness of the joints and the contracture of the soft tissue were alleviated. The range of motion of the proximal interphalangeal joints was ranged from 60 degrees to 90 degrees, while the distal interphalangeal joints from 40 degrees to 80 degrees. According to the Criteria of Upper Limb Function Evaluation by Chinese Society of Hand Surgery, the cases were ranked excellent 10 cases, good 3 cases, fair 3 cases, the excellent/good rate reached 81.25%. Conclusion Replantation of the remaining part of articular cartilage treating partial interphalangeal cartilage defect can achieve favorable clinical results.
