Functional Outcome of Arthroscopic Anterior Cruciate Ligament Reconstruction with Bone Patellar Tendon Bone Graft Using Lysholm Score

Arthroscopic Anterior Cruciate Ligament Reconstruction and Bone Patellar Bone Tendon

Abstract

Background: Arthroscopic ACL reconstruction using the "gold standard" Bone-Patellar Tendon-Bone (BPTB) graft is crucial for restoring knee stability. The Lysholm knee scoring scale is a validated global tool for objectively evaluating postoperative functional recovery in these patients. Objective: To evaluate the mean Lysholm score following arthroscopic anterior cruciate ligament (ACL) reconstruction with bone patellar tendon bone (BPTB)graft. Study Design: Descriptive case series.  Settings: Department of Orthopedic Surgery at KEMU/Mayo Hospital, Lahore Pakistan. Duration: 06 months (September 2024-January 2025). Methods: The sample had 80 patients. A 95% confidence range, 1% margin of error, and an estimated post-treatment Lysholm score of 85.49±9.0 were used. Non-probability consecutive sampling was utilized. Patients with clinical and arthroscopically verified ACL tears aged 18–70, both genders, were included. Analysis of data using SPSS version 25.0 yielded mean ± S.D. values for BMI and baseline Lysholm score at 3 months. A post-stratification t-test was used, with a significance level of p-value < 0.05. Results: The study has 80 participants. The average age at operation was 28.25 ± 8.32 years. Surgery was conducted 17.5 ± 10.3 weeks post-injury on average. 16 patients had concurrent medial meniscal injuries, while 10 had lateral tears. There were few postoperative problems. Two patients (6.25%) had superficial infections that were treated with oral antibiotics. The most prevalent follow-up symptom was anterior knee pain, reported by eight patients. Lysholm score improved significantly at 3 months. Conclusion: ACL reconstruction using the BPTB graft technique has been shown to produce promising functional outcomes, as evidenced by both objective assessments and patient-reported measures.
