In 2015, in a private clinic, a 25-year-old patient with ACL rupture underwent ACL prosthetic replacement. After the operation, the patient was worried about recurrent synovitis of the knee joint and after rehabilitation instability in the knee joint began to worry. In another private clinic the patient underwent removal of the ACL prosthesis and the filling of the bone tunnels with artificial bone replacement material.
In 2018 due to instability of the knee joint the patient came to our clinic. At the time of treatment positive Lachman, anterior drawer and pivot-shift tests were found.
