Evaluation of functional outcome of arthroscopic isolated anterior cruciate ligament reconstruction with quadriceps tendon

Background: The anterior cruciate ligament (ACL) is one of the most important intra-articular ligaments in the knee joint. It is regarded as the main barrier preventing the tibia from anteriorly translating onto the femur. The greatest incidence occurs in 15 to 25-year-old participants of work and pivoting sports. This study aimed to assess the functional outcome of arthroscopic isolated ACL reconstruction with quadriceps tendon. Methods: This was a prospective interventional study conducted in the Department of Orthopaedic Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh during the period from March 2020 to August 2022. In our study, we included 30 patients with anterior cruciate ligament injuries who attended the orthopaedic department within the study period. Results: The preoperative Lysholm score was found to be poor in all cases. Nine months after arthroscopic isolated ACL reconstruction with quadriceps tendon Lysholm score was found as excellent in 18 (60%) cases, good in 8 (26.7%), and fair in 4 (13.3%) cases. During the last follow-up of 9 months after arthroscopic isolated ACL reconstruction with quadriceps tendon, 26 (86.7%) patients were found as satisfactory results, and only 4 (13.3%) patients were found as unsatisfactory. A significant difference was observed between preoperative and postoperative functional outcomes. Conclusions: In our study, we found that arthroscopic isolated ACL reconstruction with quadriceps tendon showed satisfactory functional outcomes for the treatment of ACL injury, and all the functions of the knee were improved in compared with their pre-operative status.
