Patient-Centric Customised Isokinetic Training Improves the Muscular Performance and Physical Function of an Individual with Bone-Patella Tendon-Bone Autograft Anterior Cruciate Ligament Reconstruction: A Case Report

Abstract

Background:
Anterior Cruciate Ligament Reconstruction using Bone-Patella Tendon-Bone autograft is a commonly performed surgical procedure to restore knee stability. Postoperative rehabilitation plays a vital role in optimizing muscle performance and restoring functional mobility. However, the application of individualised isokinetic training combined with task-specific biofeedback remains limited in clinical practice.

Case Presentation:
This case report presents a 23-year-old male who underwent Anterior Cruciate Ligament Reconstruction using Bone-Patella Tendon-Bone autograft following a sports-related injury. A six-week rehabilitation program was implemented, emphasizing patient-specific progressive isokinetic training and task-specific biofeedback exercises using an isokinetic dynamometer.

Methods:
The rehabilitation protocol was tailored to the individual's strength profile and functional goals, incorporating real-time visual and auditory feedback to improve neuromuscular control. Outcome measures related to muscular performance and physical function were assessed both before and after the intervention. Objective assessment of muscle performance was done through isokinetic testing, while physical function and knee-related quality of life were evaluated using the Knee Injury and Osteoarthritis Outcome Score.

Results:
Following the intervention, the subject showed consistent and significant improvements in isokinetic strength parameters and functional performance. Increases in muscle torque, endurance, and improvements in the Knee Injury and Osteoarthritis Outcome scores indicated positive clinical outcomes. The individualised protocol was well-tolerated, with no adverse effects reported.

Conclusion:
The novel patient-centric customised isokinetic training, combined with task-specific biofeedback exercises, significantly improved both muscle performance and physical function in this post-Anterior Cruciate Ligament Reconstruction individual. This case report demonstrates that muscular performance and physical functions can be effectively enhanced through a structured and individualised isokinetic rehabilitation program, suggesting promising applications for broader clinical use.
