Natural or prosthetic knee joint tensioning device for knee arthroplasty, has femoral and tibial inserts with condylar and tibial plate support surfaces, and unit to maintain knee tensioning during joint rotation for different angles
Natural or prosthetic knee joint tensioning device for knee arthroplasty, has femoral and tibial inserts with condylar and tibial plate support surfaces, and unit to maintain knee tensioning during joint rotation for different angles
The device has femoral and tibial inserts (8A, 10A) with condylar and tibial plate support surfaces (20A, 24A) for a femoral or tibial implant. A unit (30A) applies predetermined intensity distraction force, between the inserts even if the kneecap is in place or not. A maintaining unit maintains tensioning of the knee during rotation of the knee joint for different rotation angles.
