A Functional Training with Neurokinetic Control Exercises for ACL Reconstruction in Restoring Movement Efficiency and Injury Prevention: A Single Case Study with 6-Month Follow-up

Abstract

Anterior Cruciate Ligament (ACL) injuries are common in active individuals and often require surgical reconstruction, followed by structured rehabilitation to restore function and prevent reinjury. This case report presents the rehabilitation journey of a 28-year-old male who sustained an ACL tear in a motorcycle accident and underwent ACL reconstruction using Semitendinosus and Gracilis grafts. Rehabilitation commenced three weeks post-surgery, emphasizing pain management, range of motion (ROM) recovery, and muscle strengthening in the early phases. As the patient progressed, advanced training integrated functional exercises, plyometric drills, differential learning, and visual-motor training to enhance neurokinetic control and movement efficiency. Over six months, the patient demonstrated substantial improvements, including pain reduction (NPRS score from 9 to 1), ROM flexion gain (30° to 130°), quadriceps strength increase (50 Nm to 200 Nm), and hamstring strength recovery (40 Nm to 170 Nm). Gait mechanics also improved, with enhanced step length and cadence. Statistical analysis confirmed a large effect size in pain reduction and ROM gains, highlighting the potential of multimodal rehabilitation for effective recovery. This approach may reduce reinjury risk by enhancing neuromuscular control and movement efficiency. Further research is recommended to explore long-term functional outcomes and the potential role of blood flow restriction training in ACL rehabilitation.
