Knee Replacement Surgery



Do I Need a Knee Replacement?


A total knee replacement is a major surgery, and deciding to have the surgery is a big decision. Knee replacement surgery needs to be considered after all conservative treatments have been exhausted and you have not experienced positive results. If you have a stiff, painful knee that prevents you from performing even the simplest of activities and other treatments are no longer working, surgery can be an effective option. Among other things, total knee replacement surgery is used to correct knee joint or bone trauma and mild valgus or varus deformity.


There are two types of knee replacements: partial replacements and total replacements. The below x-rays show a patient who had partial replacements on both knees. The metal prosthesis is only on one side of the knee, where the arthritis, or cartilage loss, was the most severe. The type of replacement needed depends on a patient’s lifestyle, age, and the severity of arthritis.



How does Knee Replacement Surgery Work?


Knee replacement surgeries have been performed for years, and surgical techniques are being improved all the time. During the procedure, damaged bone and cartilage is cut away from your thighbone, shinbone, and kneecap and is replaced with a metal or plastic artificial joint. This joint is attached to the thighbone, shin, and kneecap, either with cement or special surgical material. When put together, the attached artificial parts form the joint, relying on surrounding muscles and ligaments for support and function.


Recover from Knee Replacement Surgery


The surgery comes with substantial postoperative pain, and requires vigorous physical rehabilitation to guarantee the success of the procedure. For patients to expect a good result from the knee replacement surgery, they must be ready to work hard and be an active rehab participant.


Physical therapy and occupational therapy is needed to restore motion, strength, and function. The recovery period may be six weeks or longer, and will most likely involve the use of mobility aids like crutches or a walker to enable the patient´s return to preoperative mobility.
