ABSTRACT:
The proposed apparatus for surgical treatment of the knee joint comprises two pairs of needles each of which is to be driven through one of the joint ends. Each pair of needles is secured in at least one brace so that each pair of needles forms a rigid system with the brace, said rigid system being secured on the respective joint end. The two rigid systems are interconnected by means of distractors which are rigidly coupled to one of said systems and connected to the other one by way of a four-bar mechanism.
The proposed apparatus permits exactly reproducing the movement of the knee joint, and between the joint ends there is provided a permanent minimal gap of preset magnitude completely obviating all friction between the joint surfaces.
