Analysis of fixation modalities in arthroscopic anterior cruciate ligament reconstruction

Abstract

Background: To study the functional outcome of arthroscopic reconstruction of the anterior cruciate ligament (ACL) using Lysholm scoring system. Methods: This was a prospective, interventional outcome study of 64 patients presenting to the department of Orthopaedics at Dr RML Institute of Medical Sciences, Lucknow during October 2015 to October 2016 and were diagnosed to have ACL tear both clinically and radiologically. Patients were selected through a stringent inclusion and exclusion criteria. All the patients were subjected to ACL reconstruction by arthroscopic technique. Follow-up was done at three weeks, six weeks, three months, six months, nine months and one-year interval to assess the progress of rehabilitation by clinical examination and Lysholm scores. Results: Total 64 patients were included in the study. The age group of patients ranged from 18-45 years. Most of the patients (60.37%) were of physically active age group (18-30) years. Most common mode of injury was road traffic accident in 37.5% of cases followed by sports activity in 29.68%. Most of the patients came with the time duration of 1-5 months since the date of injury. The most common complaint was of the instability of knee in the form of giving way evaluated by Lachman test. The pre-operative mean Lysholm knee score was 69.06. Around 82.75% of patients reported outcome as excellent and good according to Lysholm score in the postoperative period. Anterior knee pain was the most common postoperative complaint.Conclusion: Arthroscopic anterior cruciate ligament reconstruction by quadrupled hamstring tendon graft gives satisfactory results in short-term follow-up regarding patient satisfaction, and return to near normal activity. Large-scale study with long-term follow-up is required to corroborate findings of the study and to find out long-term functional results.
