Description

technical field [0001] The present invention relates generally to the field of orthopedics, and more particularly to the design of an implant for use in arthroplasty. Background technique [0002] Patients suffering from the pain and inconvenience caused by osteoarthritis and rheumatoid arthritis have the option of joint replacement surgery. Joint replacement surgery is very common and enables many individuals to live a normal life in situations that would not otherwise be possible. Artificial joints typically include metal, ceramic, and / or plastic components that are fixed to existing bone. [0003] This joint replacement surgery is also known as arthroplasty. Arthroplasty is a well-known surgical procedure for replacing a diseased and / or damaged joint with a prosthetic joint. In a typical total arthroplasty, the end or distal portion of the bone near the joint is resected, or a portion of the distal portion of the bone is removed, and a prosthetic joint is secured there...
