Abstract
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.
Highlights
Motion capture analysis (MCA) is being actively used to uncover the mechanisms of noncontact injuries to the anterior cruciate ligament of the knee joint [10]. 3D MCA has been proposed for adoption into clinical practice as a tool for monitoring rehabilitation in patients with knee joint injuries and assessing the risk of re-injury [11]
The analysis showed that the amplitude of left lower leg flexion and extension at the knee joint during one gait cycle was reduced in the patient, as compared with the healthy subject (Fig. 2, Table 3)
The authors concluded that MCA could be recommended as a simple and accurate method for assessing knee joint stability and predicting changes of returning to sports after anterior cruciate ligament reconstruction [12]

An injury to the knee ligament apparatus is a pathology that involves one or more ligaments of the knee joint [1]. It is more prevalent among young able-bodied working-age men actively engaged in sports and exercise and is one of the most common traumatic and orthopedic injuries that compel the patient to seek medical help [1, 2].
