Rehabilitation following a minimally invasive procedure for the repair of a combined anterior cruciate and posterior cruciate ligament partial rupture in a 15-year-old athlete

BACKGROUND: The healing response procedure is a minimally invasive arthroscopic surgical technique used to stimulate healing in the treatment of partial cruciate ligament tears. The purpose of this report is to provide information on the surgical procedure, the postoperative rehabilitation, and the overall functional results in a patient who underwent such a procedure. CasE DEsCriPTion: A 15-year-old male, who sustained a partial tear of both the anterior cruciate and posterior cruciate ligament while playing football, underwent arthroscopic surgical management utilizing a healing response technique. Precautions concerning range of motion and resisted activities were followed postoperatively to protect the healing cruciate ligaments. The postoperative protocol consisted of 3 phases, culminating in return-to-sport training. Treatment incorporated cardiovascular, proprioceptive, strength, power, plyometric, and sport-specifc activities. Treatment was progressed based on specifc criteria emphasizing proper movement patterns and eccentric control during functional activities. ouTCoMEs: The patient attended 31 physical therapy sessions over 17 weeks. Strength improved from 3/5 to 5/5, knee range of motion returned to normal, Lower Extremity Functional Scale scores improved from 21/80 to 80/80, and successful outcomes on functional return-to-sport testing allowed the patient to return to competitive athletics. DisCussion: Primary repair of cruciate ligament tears has yielded poor results, and partial cruciate ligament tears may not require complete surgical reconstruction. The healing response technique ofers a possible solution for the treatment of partial cruciate ligament tears. A criterion-based postoperative protocol was derived based on current evidence regarding rehabilitation following cruciate ligament reconstruction and evidence regarding lower extremity rehabilitation principles and injury prevention.
