A tool for custom-made instruments and implant for artificial knee joint of dogs

Abstract

Total knee replacement is the standard treatment for advanced knee osteoarthritis. An improved method of treating an osteochondral defect for knee osteoarthritis of dogs is provided, which is a composite tissue for treating or preventing a disease, disorder, or condition associated with an osteochondral defect with new technique. The new technique of custom made instruments and implants for dog and small animals is applied for different breeds of dogs regardless of their sizes and weights. The tool is a custom made instruments, which is based on capture of image based (CT or computed X-ray) to be transferred to electronic 3D model and apply 3D preoperative planning to design the tools are used to perform the knee surgery.

1 . A Tool for preparing an artificial knee joint for a dog and small animals while undergoing total knee arthroplasty (TKA) surgery.
 A method of planning and complete virtual surgery of TKA leading to the production of the tool mentioned in claim one   The Tool consists of two parts; a femoral part and a tibial part   The Tool is designed as a complete cutting guide that match the surface of the bone.   Surface matching of the device relies on protruding locating surface that match bony surfaces   This technology is suitable for knee replacement for different breeds of dogs regardless of its sizes.   This technology does not need preoperative coupling with other surgical instruments such as drills or sleeves that are related to a particular company.   This technology can replace the conventional instruments for TKA such as intramedullary, extra-medullary guides, sizing, rotation guides for both tibial and femur.   The femoral implant unlike previous implants does not extend to the trochlea   The femoral implant has a good anterior pegs and a central stem
