Abstract
INTRODUCTION : The Anterior cruciate ligament injuries are more prone to occur in sports like football, volleyball, basketball, hockey, kabbaddi etc., More than 70% of these occur through non-contact activities, while 30% due to direct impacts during gaming. The injury happens while decelerating during cutting, twisting, moving to side and improper landing. Nearly 50% of ACL injuries involve damage to meniscus and articular cartilage and other ligaments. The most commonly occurring ligament injury in knee joint is anterior cruciate ligament, which accounts for a significant functional impairment. The ruptured ACL is surgically reconstructed using autogenous grafts, which can affect an individual’s early return to sporting activities. The recent advances in ACL rehabilitation are focusing on aggressive restoration of range of motion and strength, with an accelerated protocol for early return to sporting activities within 4-6 months after surgery. Maintaining cardio-vascular conditioning, proprioception and muscular co-ordination with appropriate exercises are focused in ACL rehabilitation. Many ACL reconstructed patients have weakness of muscle even after the rehabilitation, and more specifically weakness of quadriceps is seen in patients, experiencing poor functional abilities. AIM OF THE STUDY : The aim of the study is to analyze the effectiveness of cross eccentric quadriceps strength training on functional disability in collegiate football players with ACL reconstruction. OBJECTIVES OF THE STUDY : 1. To find out the effect of proprioceptive training along with standard ACL rehabilitation on functional disability in collegiate football players with ACL rehabilitation. 2. To find out the effect of cross eccentric quadriceps strength training along with standard ACL rehabilitation on functional disability in collegiate football players with ACL rehabilitation. 3. To compare the effect of proprioceptive training and cross eccentric quadriceps strength training on functional disability in collegiate football players with ACL rehabilitation. METHODOLOGY : Study Design : Pre-test and post-test experimental study design. Study Setting : Department of physiotherapy, KG Hospital, Coimbatore. Study Sample : Based on selection criteria, 30 players were selected and they were allotted into 2 groups by simple random sampling method. N=30, Group A (n=15), Group B (n=15). Group A - Control group : Subjects received proprioceptive training along with standard ACL rehabilitation. Group B - Experimental group : Subjects received cross eccentric quadriceps strength training along with ACL rehabilitation. Study Duration : The total study was conducted for a period of 6 months and each patient received treatment for a period of 8 weeks, after which follow up was done. CRITERIA FOR SELECTION : Inclusion Criteria : • Male collegiate football players. • Age between 20-30 years. • Players with Grade II ACL rupture undergone ACL reconstruction with patella tendon bone graft. • Players with no other previous injuries. • Players with unilateral ACL Reconstruction. • Players who are willing to participate in the study. Exclusion Criteria: • Players with any other ligament injuries. • Leg length discrepancy. • Any pain in the knee joint that was not related to the ACL injury. • Players with any associated injuries to Hip or Ankle joint. • Players with any cardiovascular problems. • Other sports players were excluded. SUMMARY AND CONCLUSION : This study analyzes the effectiveness of cross eccentric quadriceps strength training on functional disability in collegiate football players with ACL reconstruction. In the thirty players with ACL reconstructed knee, the functional disability was tested by lysholm knee scale and single leg hop test. They were divided into control and experimental group, with 15 players in each group. Experimental group players were given cross eccentric quadriceps strength training along with standard ACL rehabilitation and control group were given proprioceptive training along with standard ACL rehabilitation. The duration was 8 weeks after which follow up were done for 6 months. 2 weeks after ACL reconstruction the functional disability was measured using lysholm knee scale and single leg hop test. At the end of the treatment on 11th week functional disability was checked again. The results were analyzed by using student ‘t’ test. It showed that cross eccentric quadriceps strength training along with standard ACL rehabilitation given to the experimental group proved to be superior than proprioceptive training along with standard ACL rehabilitation, which is given to the control group. The analysis of results showed that following cross eccentric quadriceps strength training along with standard ACL rehabilitation reduced functional disability in players with ACL reconstruction. Cross eccentric exercise has beneficial and long term effects on the quadriceps strengthening in the early phase of ACL rehabilitation, when a player is unable to do exercise in the ACL reconstructed knee. The risks are also very minimal and early return to sporting activities can be achieved.
