| Study Objective- The study evaluates the isokinetic strength recovery of the knee joint at 4 months and 6 months following arthroscopic anterior cruciate ligament reconstruction using different grafts (peroneus longus vs. hamstrings). It aims to evaluate and compare isokinetic strength recovery and return to sports following arthroscopic anterior cruciate ligament reconstruction using peroneus longus versus hamstring autograft. Study Design-Prospective Randomised Comparative Study. Study Centre:-The Study Will be conducted at Department Of Sports Medicine, Pt. B. D. Sharma PGIMS, Rohtak. Study period- From January 2025 to December 2025 Study population-All patients fulfilling inclusion criteria attending Sport Medicine OPD at Pt. B. D. Sharma PGIMS, Rohtak. Randomisation and Group Allocation- Patients attending Sports Medicine OPD at Pt. B.D. Sharma, PGIMS, Rohtak with anterior cruciate ligament injuries planning to undergo arthroscopic anterior cruciate ligament reconstruction will be randomly allocated to one of the following two groups using computer-generated random numbers. Group A- Arthroscopic anterior cruciate ligament reconstruction using peroneus longus tendon autograft (n=25). Group B- Arthroscopic anterior cruciate ligament reconstruction using hamstring autograft (n=25). Inclusion- 1. Athletes with age group between 18-45 years of either sex. 2. Athletes with symptomatic Anterior Cruciate Ligament injury (Grade 2 and 3) with or without Meniscus injuries. Exclusion: Strict adherence to exclusion criteria. Postoperative Protocol-ACL rehabilitation physiotherapy protocol is followed. Measurements and Assessments- Isokinetic Strength Testing: Conducted preoperatively, 4 months, and 6 months postoperatively. Measurements include knee extension (Ex) and flexion (Flx) at angular velocities of 60°/s and 180°/s using a Biodex dynamometer. H/Q ratios recorded to assess muscle strength symmetry. Outcome Evaluation: Return to sports criteria:H/Q ratio ≥60% at 60°/s. Less than 10% deficit in quadriceps/hamstring strength compared to the healthy side. Less than 10% deficit in limb symmetry on single-leg hop testing. Subjective assessments using Lysholm Knee Score and AOFAS Ankle Score. Donor Site Morbidity: Assessed through physical performance and subjective evaluations. Key Results Expected- Comparison of functional outcomes (e.g., muscle strength, Return to sports timing) between graft types. Understanding rehabilitation needs and donor site morbidity. |
