Replacement arthroplasty or joint replacement surgery, a procedure of orthopedic surgery, a kind of surgery in which an arthritic or dysfunctional joint surface is to be substituted with an orthopedic prosthesis. Considered as a treatment in case of severe joint pain or dysfunction is not alleviated by less- invasive therapies, joint replacement is a type of arthroplasty which is often indicated from various joint diseases which include of osteoarthritis and rheumatoid arthritis. This joint replacement surgery has become very much common with knees and hips replaced much often.
- Shoulder: In case of shoulder replacement, a few major approaches that are used to access the shoulder joints. The first one includes of the deltopectoral approach which is needed to save the deltoid but in this supraspinatus is required to be cut. The second type of approach includes of the trans-deltoid approach which provides a straight on approach at the glenoid. The deltoid is however put at risk for potential damage during such kind of approach. Both the techniques are to be done depending on the surgeon ’s preferences.
- Hip: In case of hip replacement, a total replacement or a hemi- replacement is performed. The total replacement constitutes of the replacement of both the acetabulum and the formal head while in the case of hemiarthroplasty, only the replacement of femoral head is took place. This hip replacement is currently the most common orthopedic operation, although the patient satisfaction varies widely on the short and long-term basis.
- Knee: This kind of replacement involves of the exposure of the front of the knee with the detachment of the part of the quadriceps muscle from the patella. This patella is been displaced to either side of the joint to allow the exposure of the distal end of the femur and the proximal end of the tibia. Now, the ends of these bones are been cut accurately to shape using cutting guides that are oriented to the long axis of the bones. This operation requires vigorous physical rehabilitation.
