About

Anterior cruciate ligament (ACL) rupture is a common knee injury that frequently requires surgical reconstruction and extensive postoperative rehabilitation. Preoperative rehabilitation (prehabilitation) has been suggested as a strategy to optimize physical function before surgery and enhance postoperative recovery. This prospective randomized controlled trial aims to evaluate the effectiveness of a structured six-week prehabilitation program on functional outcomes following anterior cruciate ligament reconstruction (ACLR). Seventy-six participants with complete ACL rupture scheduled for primary ACLR were randomly assigned to either a prehabilitation group or a control group receiving standard preoperative care. The prehabilitation program consisted of progressive strengthening exercises, neuromuscular training, balance exercises, and functional movement training performed three times per week. Functional outcomes were assessed at baseline, immediately before surgery, and at three and six months postoperatively using the International Knee Documentation Committee (IKDC) Score, the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Tegner Activity Scale, and the Single-Leg Hop Test. The study aims to determine whether preoperative prehabilitation predicts improved postoperative functional recovery after ACL reconstruction and to provide evidence for optimizing rehabilitation strategies in this patient population.

Full description

Anterior cruciate ligament (ACL) rupture is one of the most common knee injuries among physically active individuals and is frequently managed with ACL reconstruction (ACLR). Despite advances in surgical techniques and postoperative rehabilitation, many patients continue to experience deficits in strength, neuromuscular control, and functional performance after surgery. Optimizing physical function before surgery may contribute to improved postoperative recovery. Preoperative rehabilitation, commonly referred to as prehabilitation, has been proposed as a strategy to enhance muscle strength, improve neuromuscular function, and prepare patients for postoperative rehabilitation. However, evidence regarding its effectiveness in improving functional outcomes following ACL reconstruction remains limited.

This prospective randomized controlled trial was designed to evaluate the impact of a structured six-week prehabilitation program on postoperative functional outcomes in individuals undergoing primary ACL reconstruction. Participants diagnosed with complete ACL rupture and scheduled for surgery were randomly assigned to either a prehabilitation group or a control group receiving standard preoperative care.

The prehabilitation program included progressive strengthening exercises, neuromuscular training, balance training, and functional movement exercises performed three times weekly under supervision. Participants were followed throughout the perioperative period and during postoperative rehabilitation.

Functional recovery was evaluated using validated patient-reported outcome measures and functional performance assessments at predefined time points before and after surgery. The study seeks to determine whether preoperative prehabilitation contributes to superior functional recovery and improved return-to-activity outcomes following ACL reconstruction.
