Evaluation of the Outcome of Arthroscopic ACL Reconstruction by Quadrupled Hamstring Tendon Graft and Fixation with Biodegradable Screw in ACL Injury

Abstract

Background: The BPTB graft and quadruple graft of semitendinosus and gracilis are the two most popular options for anterior cruciate ligament reconstruction. Objective: To assess the efficacy of arthroscopic ACL reconstruction with semitendinosus and gracilis tendon grafts and biodegradable screw fixation in ACL injury. Methodology: This prospective interventional study was carried out at Dhaka Medical College Hospital and a private hospital in Dhaka from July 2014 to May 2016. Thirty-one (31) patients with ACL injuries were treated with arthroscopic reconstruction of the ACL using a quadrupled hamstring autograft of semitendinosus and gracilis tendon, as well as a rehabilitation protocol. Patients were routinely followed up on and an outcome evaluation was performed at 24 weeks. Subjective and objective evaluations were performed using the IKDC and Lysholm knee scoring scales to compare preoperative and postoperative outcomes. Results: All patients had either a grade II or a grade III positive Lachman test before surgery. There was a statistically significant improvement after surgery, with 87 percent (27 patients) having a negative Lachman test and only 13 percent (4 patients) having a positive Lachman test. The pre-operative Lysholm knee score was 53, and the postoperative Lysholm knee score was 90, indicating a significant improvement (p0.05). Excellent results (>94–100 points) were obtained in 12 (38.7 percent) patients, good results (>84–94 points) in 15 (48.4 percent) patients, fair results (>64–84 points) in 2 (6.5 percent) patients, and poor results (64 points) in 2 (6.5 percent) patients, according to the Lysholm knee scoring scale. Conclusion: Quadrupled Arthroscopic ACL Reconstruction ACL injury patients can benefit from a hamstring graft of semitendinosus and gracilis tendon and fixation with a biodegradable.
