In interpositional reconstruction, both bones of the joint are reshaped, and a disk of material is placed between the bones to prevent their rubbing together. Length of hospital stay depends on which joint is treated, but is normally only a few days. Preparation Prior to arthroplasty, all the standard preoperative blood and urine tests are performed. The patient meets with the anesthesiologist to discuss any special conditions that affect the administration of anesthesia. Aftercare Patients who have undergone arthroplasty must be careful not to over stress or destabilize the joint.
Physical therapy is begun immediately.
Antibiotics are given to prevent infection. Risks Joint resection and interpositional reconstruction do not always produce successful results, especially in patients with rheumatoid arthritis. Repeat surgery or total joint replacement may be necessary. As with any major surgery, there is always a risk of an allergic reaction to anesthesia or that blood clots will break loose and obstruct the arteries. Normal results Most patients recover with improved range of motion in the joint and relief from pain.
