An anterior cruciate ligament tear is one of the most common injuries to the capsular ligament apparatus of the knee necessitating operative treatment. Postoperatively, patients with anterior cruciate ligament injuries develop a pathologic gait pattern. Today, innovative diagnostic and rehabilitation methods for patients with gait disturbances associated with such injuries are in high demand. Below, we present a case of using 3D motion capture analysis for the personalized assessment of gait function in a patient with the reconstructed anterior cruciate ligament two months after surgery. The analysis revealed that the patient had a slower, shorter, wider step with longer step intervals than the healthy subject; the flexion and extension amplitude in the large joints of the operated leg was smaller than in the healthy contralateral leg. Motion capture analysis can be used to assess the postoperative dynamics in patients with anterior cruciate ligament tears.

A review of the literature is devoted to the problem of complications after arthroscopic reconstruction of the anterior cruciate ligament. The authors covered questions of epidemiology and surgical technique, touched on important aspects of the main complications, such as graft damage, arthrofibrosis and impingement syndrome, the formation of synovial cysts, infections, the development of osteoarthritis and cartilage degeneration. Despite the prevalence of pathology, a huge number of publications and the development of arthroscopic surgery, there are many theoretical and technical problems, that have not yet found a satisfactory solution and require further development. A relevant question for the doctor is the problem of correctly choosing the method or combination methods for anterior cruciate ligament reconstruction in relation for each patient, considering the individual characteristics and possible risks of developing different complications in patient.
