Arthroscopic Treatment of Type III Tibial Spine Fractures Using Absorbable Fixation

Over 2 years, five patients (average age 15 years) were diagnosed with a type III tibial spine fracture. All five fractures were treated with arthroscopic reduction and internal stabilization using absorbable fixation. At average 8.5-year follow-up, patients were interviewed and examined. Results were documented regarding function, KT-1000 testing, range of motion, and radiographic findings. All five patients reported no functional limitations despite participation in high-demand sports. Stability testing by KT-1000 revealed no objective instability. Range of motion was normal when the knee was immobilized in full extension postoperatively. No radiographic abnormality was noted at follow-up. An excellent result can be expected with arthroscopic treatment of these fractures using absorbable internal fixation. Postoperative immobilization in full extension is recommended.
