Postoperative rehabilitation of simultaneous rupture of anterior cruciate ligament and patellar ligament: A case report.

Introduction: The simultaneous rupture of anterior cruciate ligament (ACL) and patellar ligament (PL) is an infrequent condition. Each isolated injury has surgical techniques and rehabilitation protocols that differ widely among each other. Nonetheless, there is no established physical rehabilitation approach when both injuries are associated.

Objective: The aim of this report is to describe the rehabilitation and the outcomes obtained in the postoperative period of simultaneous rupture of ACL and PL and the follow-up period.

Case Report: A 21-year-old male patient suffered the rupture of ACL and PL after landing from a jump while playing soccer. The knee was immediately immobilized, and 10 weeks later, he was operated in a one-stage surgery. He initiated his rehabilitation 3 weeks after the surgical resolution. A three-times a week rehabilitation was implemented to restore range of motion and improve functional status. An extensive evaluation was carried out monthly using dynamic neuromuscular tests and self-reported questionnaires.

Results: At the end of the rehabilitation, he presented a complete extension and 130° of knee flexion in passive open kinetic chain. The Single Leg Squat and Landing Error Scoring System showed a good performance, while the Star Excursion Balance Test and the single hops assessments were symmetrical. The International Knee Documentation Committee and Lower Extremity Functional Scale questionnaires yielded values of 90.8% and 77 points, respectively.

Conclusion: An approach based on mobility exercises and strengthening of the lower limbs and the core muscles, considering the biological healing times of each particular structure, made it possible to obtain satisfactory results in mobility, functional tests, self-reported questionnaires, and patient's satisfaction.
