Answer : A joint replacement surgery is performed to replace the damaged or worn-out surfaces of a joint with artificial implants. There are a number of procedures available as being alternative to a TKR or THR surgery. Though hip replacement surgery is a standard treatment for patients, a hip resurfacing surgery is available as an alternative option. In a hip resurfacing surgery, the implants are of smaller size and less amount of bone is removed. Similarly, a tibial osteotomy is available as an alternative to knee replacement surgery. Though tibial osteotomy relieves pain due to arthritis of knee, it is not recommended for all patients. Depending on the severity of the ailment, the surgeon may also suggest non-surgical treatment options like arthroscopy, cartilage cell transplantation, osteodonics etc.
