Joint arthroplasty is defined as the replacement of worn out arthritic joints in the body with artificial implants/prosthesis for pain relief, increased mobility and movements. Weight bearing joints in the body normally get worn out with increasing age. The common joints involved are the knees and hips
The other joints which rarely do get worn out are the shoulders and elbows. When this happens, the worn out bones are replaced by artificial prosthesis. These artificial prostheses mimic the original joints in term of design and function. Sometimes replacement surgeries are also indicated in young individuals because of secondary conditions leading to joint destruction and deformity such as trauma and diseases like rheumatoid arthritis.
