Aim: The present study was conducted to assess the functional outcome of arthroscopic suture pull out fixation of displaced tibial spine avulsion fracture. Methods: The present prospective study was conducted in the Department of Orthopaedics, Dr. D.Y. Patil Medical College, Hospital and Research Centre, Dr. D.Y. Patil Vidyapeeth, Pimpri, Pune, over a period of 1 year with a sample size of 60. Results: 60 patients with tibial spine avulsion were operated on with arthroscopic pull out suture technique. The majority of subjects were in the age group 18 to 30 years (66.66%). In the study, 83.34% were males and 16.66% were females. 10% had fall from the cycle, 58.34% had fallen from motorbike and 31.66% had fall while playing. Status of Physis in 60% was closed and opens in 40%. In the study 73.34% had Type III and 26.66% had Type IV Meyers and McKeever's classification. At 3 months, the mean Post op Lysholm score was 86.14±1.46, at 6 months was 96.84±2.05 and at 12 months 96.14±1.36. There was a significant increase in Post op Lysholm score at 6 months and 12 months. At 12 months when compared to 6 months Post op Lysholm score, there was no significant increase in Post op Lysholm score. 6.66% subjects had Post Op Knee Stiffness. Conclusion: The present study concluded that Arthroscopic suture pull-out fixation for type III and IV tibial spine avulsion shows excellent outcomes without any significant complications.
