Analysis of Arthroscopic ACL Reconstruction Using Single Bundle Four Strand Semitendinosus Graft in ACL Tear in Indian Patients

摘要

Purpose: The best graft option to replace the injured Anterior Cruciate Ligament (ACL) has been a matter of discussion. There has been paucity in the literature regarding arthroscopic ACL Reconstruction using four strand single Semitendinosus graft. Method: 30 patients underwent arthroscopic ACL reconstruction using single semitendinosus tendon after quadrupling the tendon and fixing on femoral side with endobutton and tibial side with interference screw. The functional outcome was compared using preoperative and postoperative Lysholm II scoring and anterior tibial translation. The secondary outcomes were measurement of harvested and quadrupled Semitendinosus graft length and thickness and its complications. Result: All patients had Poor Lysholm score pre-operatively (mean= 48) but showed improvement in Lysholm score at 3 months (mean=89) and 6 months post-operatively (mean=93). The mean pre-operative anterior tibial translation was 11.2mm. Post-operative mean anterior tibial translation was 2.96mm at 1 month, 2.93mm at 3 months and 3.5mm 6 months. Superficial wound infection at harvested semitendinosus graft site was observed in one case which resolved on daily dressing and antibiotic therapy for 7 days and recurrent knee effusion was observe in two patients who were managed conservatively in the form of anti-inflammatory medications. Conclusion: The reconstruction of the ACL by a quadrupled semitendinosus tendon graft with an endobutton and a bioabsorbable screw can achieve excellent clinical and subjective results after a short/intermediate follow-up of 6 months.
