Effect of low-moderate plyometric exercise in post anterior cruciate ligament reconstruction: A case study

Abstract

The anterior cruciate ligament (ACL) is vital for knee joint stability, and its injury is a common concern in active individuals. Despite advances in ACL reconstruction (ACLR), residual instability and performance declines remain significant issues. Diminished proprioception post-ACL rupture further complicates rehabilitation. This case study examines the efficacy of a low-moderate plyometric exercise protocol in ACLR rehabilitation.A 25-year-old male sustained an ACL injury while playing football, leading to surgery. Post-surgery, he underwent an 8-week plyometric exercise program. The study assessed knee strength, range of motion, and functional outcomes using the International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS).Results showed significant improvements in knee strength, range of motion, and functionality post-intervention without adverse effects. Plyometric training enhanced muscle strength and function, crucial for post-ACL surgery rehabilitation. The study supports the role of plyometric exercises in ACLR recovery, offering a safe and feasible approach to improve outcomes.This study underscores the importance of incorporating plyometric exercises in ACLR rehabilitation protocols, emphasizing its potential to enhance functional recovery and lower limb power. Further research with larger sample sizes is warranted to validate these findings and optimize ACLR rehabilitation strategies.
