Study of arthroscopic anterior cruciate ligament reconstruction using single bundle hamstring auto-graft by trans-portal technique
Keywords:Knee, Arthroscopy, Modified cincinnati rating system, ACL reconstruction
Background: Anterior cruciate ligament (ACL) tear is a serious injury that results in immediate knee instability, lengthy rehabilitation and increased risk of early onset knee osteoarthritis. The goal of anatomic reconstruction is to place the ACL graft at a more anatomic location on both tibia and femur. The purposes of the study were to evaluate the outcome of trans-portal arthroscopic ACL reconstruction clinically and radiologically and to compare the results with reported studies.
Methods: 52 patients with complete tear of the ACL were treated with arthroscopic ACL reconstruction. The patients were regularly followed up at 4, 8, 12 and 24 weeks whereby laxity, pain and range of motion were assessed.
Results: There were 43 male and 9 females with the mean age being 30.38 years. Left sided injury was more common seen in 31 patients (59.62%) where domestic twist injury caused most of the ACL tears. Only 4 cases (7.69%) had isolated ACL tears and lateral meniscus was the most common associated injury found in 25 patients (48.07%) Average operative time was 113 minutes. Pain was the most common post-op complication seen in 16 patients (30.76%) while laxity was noted in 4 patients. Average flexion of 111.44 degrees was reached at 6 months. 37 cases (71.15%) had excellent post-op outcome at 6 months as per the modified cincinnati rating system.
Conclusions: ACL reconstruction using the arthroscopic trans-portal technique provides good post-op knee stability and satisfactory range of motion.
