Arthroscopy is a minimal invasive surgery where with the help of a very fine telescope, the orthopaedic surgeon looks into the joint to locate any anomaly which causes discomfort to the patient. Further, the problem can be rectified at the same time. This surgery is in general involved with injuries to the ankle, wrist, hip, knee, shoulder and elbow.
Total Knee replacement is a surgical procedure in which damaged components of the knee joint are substituted with artificial parts. The surgery is performed all the way through a incision at the anterior of the knee exposing the muscular, ligamentous and bony components of the joint.
Types of artificial knees: There are two major types of artificial knee replacements -
• UNCEMEMTED PROSTHESIS
• CEMENTED PROSTHESIS
Both are widely used and in many cases, a combination of both is used. Prosthesis comprises of three main parts –
• The tibial constituent (bottom segment) substitutes the top surface of the lower bone, the tibia.
• The femoral constituent (top segment) replaces the bottom surface of the upper bone (the femur) and the furrow where the patella fits.
• The patellar component (kneecap portion) replaces the patella surface where it glides in the fissure on the femur.
The partial knee replacement procedure has invoked momentous interest lately as it uses a minor incision and has quicker recovery rate as compared to the traditional total knee replacement surgery. Partial knee replacement comes under the category of minimally invasive surgery. The intention is to remove only the severely damaged region of cartilage from the Joint, and leave any strong parts of the Joint for continual use. Often partial knee replacements place implants between the end of the thigh bone and the apex of the shin bone.
The replacement of an original knee with an artificial substitute does not guarantee a total restoration of the functions but a near normal function is still realizable. There is a drastic improvement in the joint movement with a relief from chronic stiffness and pain. A person can be on his own for a long time and perform the routine, day to day activities like walking, climbing, driving independently.
Knee replacement surgery involves replacing some or all of the components of the knee joint with a synthetic implant, to repair the damaged weight-bearing surfaces that are causing pain. A total knee replacement surgery replaces all three compartments of the diseased knee joint. A partial knee replacement involves an implant in just one or two compartments of the knee, retaining any undamaged parts. While there are non-surgical and surgical interventions short of knee replacement which will often provide temporary relief, the long-term resolution to most knee degeneration will be joint replacement.
There are several different implant designs but each will offer renewed stability and movement. Over all, there are two main benefits to be gained from knee replacement surgery
• Elimination of pain.
• Improved range of motion.
Of all possible surgical interventions, total knee replacement offers the greatest quality of life improvement. The procedure has a high rate of success. Partial knee replacement is not possible for all patients with arthritis, indeed, it is indicated when the arthritic condition is fairly localized. However, when it is appropriate, it is important to educated patients of the pros and cons of partial vs total knee replacement.
Both partial and total knee replacement can provide durable pain relief and improve function in patients with knee arthritis. Partial knee replacement is not appropriate for all patients with knee arthritis and may only be possible in 10-30% of patients.
Total Knee replacement is a very durable operation that can last for 30 years. It predictably allows patients to walk, hike, ride a bike and swim.
A downside of partial knee replacement is that it may not be as long-lasting as Total Knee Replacement. One of the primary reasons for this is that Partial Knee Replacement can fail quickly if they are poorly positioned at the time of surgery. Indeed, PKR is a technically demanding procedure, and prone to surgeon error.
In a total hip replacement surgery, there is a replacement of the thigh bone and the socket with implant prostheses.
Patients opt for this surgery when they have severe arthritis persistent distressing pain, excessive stiffness of the hip etc. Bipolar type of prosthesis has a femoral head that spins around the stem. The bipolar prosthesis was designed to lessen the wear and tear on the articular cartilage inside the acetabulum.
Both types seem to work well. A cemented prosthesis is composed of an epoxy cement that alligns the metaI to the bone. An uncemented prosthesis on the other comprises of a fine web of holes on the surface allowing bone to grow into the mesh and attach the prosthesis and bone together The choice of prosthesis depends on your age, the state of your bones your lifestyle and the surgeon's understanding.
A total hip replacement will provide absolute or nearly plete respite from pain in majority of the patients. It will permit patients to Advantages of Arthroscopic Surgery. It represents:
• SHORT STAY IN THE HOSPITAL
• LESS BLEEDING AND LESS COMPLICATION
• LESS PAINFUL PROCEDURE
• NEAR NORMAL RESTORATION OF JOINT FUNCTION
• VERY SMALL SCAR
