The surgical repair of a defect of tendinous distortion of the patella and of the joint capsule during an arthrolysis of the knee joint.

The suture of tissues resected during surgical tendomyolysis and arthrolysis of the knee joint required by its extension contracture is carried out during tibial flexion at an angle of 90 degrees. This can lead to the development of a diastasis of the tendinous distortion of the patella and of the joint capsule which prevents the suture of the wound. It is suggested to repair the resulting tissue defect with the use of a split flap of local tissues with a wide base situated in front of the defect. The flap is dissected from the lateral part of the tendinous distortion and of the capsule. The flap is turned by 180 degrees around its base and extended to cover the defect with its subsequent suture to the opposite edge of the defect. The described supplementary surgical procedure is technically uncomplicated and results in stable anterior and lateral joint structures, in a reduction of the risk of complications due to infection, and allows an early initiation of active kinesitherapy in the early postoperative period.
