Summary

Results show that Arthroscopic suture fixation of the comminuted tibial spine is promising and reliable technique to achieve the best biomechanics of the knee..

Abstract

Introduction

Tibial spine fractures are common injuries and various techniques have been described for the fixation. The purpose of the article is to make familiar with the arthroscopic fixation of the anterior cruciate ligament bony avulsion injuries using non absorbable sutures and simple methods and instruments. Adequate reduction, anterior cruciate ligament integrity and regaining the bio-mechanics of the knee are the ultimate goal to be achieved failing which non union and malunion ensues. This technique has resulted in achieving excellent results and thus avoiding complications like joint laxity, flexion deformity & pain.

Methods

Twenty one patients underwent arthroscopic suture fixation of the comminuted tibial spine fractures. Mean age of the patient was 24.28 years (range 16 to 38 years). All of the patients belonged to the Meyer type IV. The mean duration of follow up was 15.5 months with a minimum of one year follow-up.

Results

All patients showed negative Lachman test except one having grade 1 positive Lachman's test. No patient showed extension loss. 90.4 % (n=19) patients had an IKDC grade A while two patients belonged to grade B. All patients returned to their previous activity level.

Conclusion

The above excellent results show that arthroscopic suture fixation of the comminuted tibial spine is promising and reliable technique to achieve the best biomechanics of the knee.
