Arthroplasty

Arthroplasty is an operative procedure of orthopaedic surgery performed, in which the arthritic or dysfunctional joint surface is replaced with something better or by remodeling or realigning the joint by osteotomy or some other procedure. Previously, a popular form of arthroplasty was interpositional arthroplasty with interposition of some other tissue like skin, muscle or tendon to keep inflammatory surfaces apart or excisional arthroplasty in which the joint surface and bone was removed leaving scar tissue to fill in the gap. Other forms of arthroplasty include resection arthroplasty, resurfacing arthroplasty, mold arthroplasty, cup arthroplasty, silicone replacement arthroplasty, etc. Osteotomy to restore or modify joint congruity is also an arthroplasty.For the last 45 years the most successful and common form of arthroplasty is the surgical replacement of arthritic or destructive or necrotic joint or joint surface with prosthesis. For example a hip joint that is affected by osteoarthritis may be replaced entirely with a prosthetic hip. This would involve replacing both the acetabulum and the head and neck of the femur. The purpose of this procedure is to relieve pain, to restore range of motion and to improve walking ability, thus leading to the improvement of muscle strength.Indications for arthroplasty include:*osteoarthritis *rheumatoid arthritis *avascular necrosis or osteonecrosis *congenital dislocation of the hip joint *acetabular dysplasia *frozen shoulder, loose shoulder*traumatized and malaligned joint*joint stiffnessCategory:Orthopedicshr:Artroplastikaro:Artroplastie Arthroscopy Arthroscopy is a minimally invasive surgical procedure in which an examination and sometimes treatment of damage of the interior of a joint is performed using an arthroscope, a type of endoscope that is inserted into the joint through a small incision. Arthroscopic procedures can be performed either to evaluate or to treat many orthopaedic conditions including torn floating cartilage, torn surface cartilage, ACL reconstruction, and trimming damaged cartilage.The advantage of arthroscopy over traditional, open surgery is that the joint does not have to be opened up fully. Instead, only two small incisions are made - one for the arthroscope and one for the surgical instruments. This reduces recovery time and may increase the rate of surgical success due to less trauma to the connective tissue. It is especially useful for professional athletes, who frequently injure knee joints and require fast healing time. There is also less scarring, because of the smaller incisions. The surgical instruments used are smaller than traditional instruments. Surgeons view the joint area on a video monitor, and can diagnose and repair torn joint tissue, such as ligaments and menisci.Arthroscopy is used for joints of the knee, shoulder, elbow, wrist, ankle and hip.
