[The biomechanical prerequisites and experimental validation of an arthroplastic method after the "rolling joint"...

The authors have proposed the idea of joint motion realization by means of rolling of one joint surface over the other one. It allows to pass over an unsolved yet problem of cartilage restoration and normal gliding in the affected joint. It has been developed a model at the knee joint of a dog, which provides for resection of the joint surfaces according to semicylinder and plane shape and introduction of lavsane bands to hold and direct movement of the articular ends. 34 dogs have been subjected to experimental operations. There was achieved good and satisfactory joint and limb function with 25 of them. Biomechanical investigation allowed to prove joint mobility and limb supporting ability.
