Perturbation Training in Anterior Cruciate Ligament Graft Tear and Posterolateral Corner Injury: A Case Report of a...

This case study illustrates how rehabilitation for combination injuries necessitates a thorough, customized strategy that includes perturbation training to address complicated biomechanical impairments because of the complex relationship between the anterior cruciate ligament (ACL) and the posterolateral corner (PCL). An 18-year-old female basketball player visited the Sports Rehab Outpatient Department with a complaint of pain in the posterior aspect of her knee, difficulty fully flexing her right knee joint, and intermittent instability one month after an injury. Her grade 2 ACL tear was accompanied by thinning of the lateral collateral ligament and strain of the popliteofibular ligament as per the MRI findings before the ACL reconstruction surgery. She underwent a knee graft sprain and ACL re-injury. The decision was made to manage the injury conservatively by implementing a rehabilitation program focused on perturbations to improve neuromuscular control and functional stability of the knee. This case report highlights the significance of a multidisciplinary approach, evidence-based interventions (such as the Lysholm score, International Knee Documentation Committee-Subjective Knee Form, and Tempa Scale of Kinesiophobia as outcome measures), and patient-centered care. This study intends to make a significant contribution to sports medicine and orthopedic rehabilitation by clarifying the complexities of rehabilitation in such complicated circumstances.
