KNEE REPLACEMENT In the contemporary times, our lifestyle habits pose a serious challenge to our body and the knees are the first to bear the brunt of these changes. Owing to such habits, many people experience knee pain caused by wear and tear, an injury or hectic routine. Some other people suffer similar pain due to aging and arthritis.

What is Knee Replacement? A total knee replacement is a surgical procedure whereby the diseased knee joint is replaced with artificial material, metal and plastic components shaped to allow continued motion of the knee.

Indications Total knee replacement can be performed to correct mild valgus (outward bending) or varus (Inward bending) deformity, if one experiences extreme pain when performing physical activities requiring a range of movement in the knee joint.

Is Knee Replacement Surgery for You? Total knee replacement surgery is considered for patients whose knee joints have been damaged by progressive arthritis (age or activity related), trauma (accidents), rheumatoid arthritis and psoriatic arthritis (disease) or other rare destructive diseases of the joint. Regardless of the cause of the damage to the joint, the resulting progressively increasing pain and stiffness and decreasing daily function lead the patient to consider total knee replacement.

Total knee replacement surgery includes 4-5 inches incision over the knee, 3-5 days of hospitalization, physical therapy can begin 24 hours after surgery. A unique device that can help speed recovery is the continuous passive motion (CPM) machine. It constantly moves the knee through various degrees of range of motion, while the patient relaxes.

Patients will start walking using a walker and crutches. Eventually, patients will learn to walk up and down stairs and grades. A number of home exercises are given to strengthen thigh and calf muscles.

One month post surgery the patient reports relief from stiffness, pain and starts enjoying social activities with were inhibited earlier.

The hip and knee arthroplasty is a reliable procedure to the present day, with favorable results over time and a success rate >90%. However, there are also reported failures, complications or residual pains which are not exempt even in the non-prosthetic implants. The implant that lasts a lifetime does not exist, even if we can predict its survival beyond the 15-20 years of operation.

The Orthopedic Surgeon and Physical therapist work together to achieve the best clinical outcome for the patient.
