- Consider reconstruction in chronic cases: Chronic RCL injuries are often not amenable to direct repair and may require reconstruction due to poor ligament quality.
- APB tendon is a viable local option: Using a dorsal half-slip of the APB tendon allows reconstruction without the need for free tendon grafts, potentially reducing donor-site morbidity and surgical complexity.
- Technique restores stability but may reduce flexion: Patients achieved stable MCP joints and functional recovery, though a consistent loss of approximately 20° of MCP flexion was noted.
- Structured postoperative protocol is important: Immobilization for 5 weeks with K-wire stabilization followed by staged rehabilitation (early IP motion, delayed MCP motion) supported recovery.
- Good short- to mid-term outcomes, but limited evidence: No complications or recurrent instability were reported, but findings are based on only two cases, highlighting the need for larger studies.
