Abstract
BACKGROUND: Tibial spine avulsion fractures (TSAFs) occur chiefly in adolescents. Few published data are available on outcomes after arthroscopic surgical treatment of TSAFs in adults. OBJECTIVES: To evaluate outcomes of consecutive patients with TSAFs managed by arthroscopic bone suture followed by a standardised non-aggressive rehabilitation programme. HYPOTHESIS: Arthroscopic bone suture followed by non-aggressive rehabilitation therapy reliably produces satisfactory outcomes in adults with TSAF. METHODS: Thirteen adults were included. Outcomes were evaluated based on the Tegner score, International Knee Documentation Committee (IKDC) score, anterior-posterior knee laxity, passive and active motion ranges, and radiological appearance. RESULTS: After a mean follow-up of 41±27months (12-94months), all 13 patients had healed fractures without secondary displacement. No patient had knee instability. Post-operative stiffness was noted in 5 patients (2 with complex regional pain syndrome and 3 with extension lag), 1 of whom required surgical release. The mean IKDC score was 91.3±11.7. The mean Tegner score was 5.46±1.37 compared to 6.38±0.70 before surgery. Mean tibial translation (measured using the Rolimeter) was 1.09±1.22mm, compared to 5.9±1.85mm before surgery. CONCLUSION: The outcomes reported here support the reliability of arthroscopic bone suture for TSAF fixation. Nevertheless, a substantial proportion of patients experienced post-operative stiffness, whose contributory factors may include stunning of the quadriceps due to the short time from injury to surgery and the use of a gentle rehabilitation programme. LEVEL OF EVIDENCE: IV, retrospective study of treatment outcomes.
