ACL injury can be treated either by conservative treatment or by reconstructive treatment. However, there is difference in opinion, which treatment has best results. Therefore, the primary aim is to compare the balance after conservative and reconstructive ACL rehabilitation in young adults. Methodology: Total 25 patients were allocated into two groups; group A was ACL reconstructive group (12 subjects) and group B was ACL conservative group (13 subjects). Duration of injury was between 5 months- 1 year. The outcome measures include Pain (VAS), Balance (Star Excursion Balance Test), Functional tests, Girth, Range of Motion (Goniometer), Strength (Strain gauge dynamometer) and Stability of joints (Special tests) respectively. Result and conclusion: The analysis of recorded data revealed that the balance remains same in both the groups after assessment. And there is no significant difference between both the treatment methods. To conclude this study, it can be stated that after both conservative and reconstructive rehabilitation, balance is equally hindered among young adults.

INTRODUCTION Balance or postural stability is a generic term used to describe the dynamic process by which the body’s position is maintained in equilibrium [15]. Balance is the process of maintaining the body’s center of gravity (CoG) vertically over the base of the support and it relies on rapid and continuous feedback from visual, vestibular and somatosensory structures for the subsequent execution of smooth and coordinated neuromuscular actions [13-14]. Balance is of two types: Static balance and Dynamic balance. Balance impairment can be caused by injury or disease to any structures involved in the three stages of information processing (i.e. sensory input, sensorimotor integration and motor output generation). Receptors located in the muscles, tendons, skin and joint structures such as in the cruciate ligaments, provide the central nervous system with information regarding the joints and body position, speed and direction of the movement. Neurophysiological experiments show that the afferent information from the ACL affects the gamma motor neurons and therefore they will contribute to functional stabilization of the knee joint [1]. This sensory information, as well as information from the visual and vestibular systems, contributes to the maintenance and
