When considering the options to treat my elbow arthritis, my doctor mentioned a surgery called interposition arthroplasty. What is this surgery, and what does it involve?

Elbow arthritis may be surgically treated with a procedure called interposition arthroplasty. The term "interposition" means that new tissue is placed between the damaged surfaces of the elbow joint. In this surgery, the surgeon takes tissue from another source to fill in the space in the elbow joint. The soft tissue forms a false joint. This surgery has best results in younger people with healthy tissue around the elbow joint.
