- Brief Summary
BACKGROUND:
Anterior cruciate ligament (ACL) is an important ligamentous structure in the knee joint which contributes in maintaining stability. ACL injury contribute to approximately 50% of knee injuries .The incidence of ACL ruptures is estimated to be between 30 and 78 per 100,000 people per year .
The incidence of ACL ruptures varies depending on a number of factors, including age, sex, sport participation, and genetics. ACL ruptures are most common in young adults, particularly women. The risk of an ACL rupture has been reported as 2-8 times higher for women than for men. A systematic review study found that the risk of ACL injury was highest in football, followed by soccer, basketball, and skiing .
Nowadays, Peroneus longus tendon (PLT) autograft is used in orthopaedic surgeries. Some studies reported that PLT graft had maintained a possible more efficient ACL substitute for its tensile strength and regeneration ability after being inserted post-surgery . The PLT graft has additional benefit as it does not cause secondary injury to the knee and its adjacent structures .
Ankle proprioception is one of the crucial components contributing to postural control . PLT graft for ACL reconstruction might affect the already compromised body balance by influencing postural stability and ankle stability at the donor ankle site. So, this study will be conducted to assess and compare the effect of ACLreconstruction with PLT graft to the effect of ACL reconstruction with HT graft on ankle stability and postural control .

Group Intervention Description Peroneus longus autograft group Isokinetic and functional balance tests * Isokinetic dynamometer is a three multi-joint testing and rehabilitation device. It will be used to measure concentric peak torques of ankle planter flexor and eccentric peak torque of evertor * The modified Star Excursion Balance Test will be used to evaluate the dynamic balance with a series of unilateral balance tests * Single leg Stance (SLS) test to assess balance, especially when performed in a static position hamstring autograft group Isokinetic and functional balance tests * Isokinetic dynamometer is a three multi-joint testing and rehabilitation device.

- Primary Outcome Measures
Name Time Method Peak torque of plantarflexors and evertors (N.m) preoperative /3 months / 6 months The isokinetic strength of ankle muscles will be evaluated at angular velocities of 30°/s and 120°/s in concentric/concentric mode for the ankle Planter flexion/dorsiflexion and in concentric/eccentric reciprocal action for the ankle eversion/eversion
Star Excursion Balance Test distance (cm) preoperative /3 months / 6 months The Modified version of the Star Excursion Balance Test with only three directions (anterior, posterolateral \[PL\], and posteromedial \[PM\]) will be used .
The patient will be given four practice trials to familiarize themselves with the task, followed by a brief rest. Then, three trials will be recorded with at least 10 seconds of rest between each trial. The average of the three trials will be normalized to the participant's leg length and used for analysis.Single leg stance time (sec) preoperative /3 months / 6 months The procedure will be repeated three times
