Orthopedic Care and Consultation

Following images are of the removed acetabular cup from previous surgery.

Joint replacement is a common orthopedic procedure done worldwide. A joint replacement aims at of replacing painful, arthritic or diseased parts of the joint with artificial surfaces.
The artificial joint is called prosthesis.
Hip and knee replacements are very common form of joint replacements. In medical terms the joint replacement is called replacement arthroplasty or total arthroplasty or sometimes simply arthroplasty.
Actually arthroplasty means repair of the joint. Earlier, a popular form of arthroplasty was interpositional arthroplasty with interposition of some other tissue like skin, muscle or tendon to keep inflammatory surfaces apart. [Read more...]
In uncorrectable painful deformities, it becomes necessary to perform either of two procedures. It is difficult to decide when to perform arthrodesis and when to do total joint replacement. Individual assessment should be carried out to aid in decision making. The treatment options should be discussed with the patient after evaluating his needs and expectation.
Most common indication for surgery is disabling pain. If involvement is unilateral and the opposite lower limb is relatively normal, arthrodesis is a good option.
Total joint replacement in bilateral knees is indicated with Stage IV or Stage V arthropathy when persistent knee pain is presesent.
Total hip replacement is indicated in Stage IV or Stage V hemophilic arthropathy when pain is persistent with severe disability not relieved by conservative measures. Arthroplasty of the elbow has been reported.
Arthrodesis of the ankle, subtalar and midtarsal joints in the foot, shoulder, or knee may be indicated when these joints are destroyed. The surgical technique is the same as in normal patients with the exception that percutaneous pins should not be utilized in hemophiliacs.
