If your knee is damaged because of an injury or accident, then knee replacement surgery may be an option to avail. This orthopedic surgical procedure is known as arthroplasty which replaces the musculoskeletal joint with an artificial part.
The surgical treatment helps in relieving pain and restoring the function of the joint after the damage. If you have pain in the knee joint, it can become difficult to perform daily activities. People who are over the age of 50 commonly seek this surgery due to wear and tear on the knee joint.
The surgeon replaces the damaged portion of the knee with plastic and metal parts. If only one part of your knee is damaged, it can be treated by partial knee replacement surgery. The replacement is done either on the inside part (medial), outside part (lateral) or the kneecap part of the knee.
This surgery removes the damaged tissue and bone in the knee joint. An artificial implant, known as a prosthetic, replaces the removed part(s). Before starting the surgery, the patient receives anesthesia which the blocks pain.
Two types of anesthesia can be used during the surgical treatment. First one is general anesthesia, which will make the patient pain free during the treatment while the patient is unconscious. The other is regional anesthesia, which is also known commonly as epidural anesthesia.
With regional anesthesia, the patient will get numb below the waist. Once the patient is anesthetized, the surgeon makes an incision above the knee, which is 3 to 5 centimeters long. After reviewing the damaged bone and tissue, they are removed. A part made of metal or plastic are inserted into the knee. Once properly place, the artificial part it is attached with bone cement, and the wound is closed.
A partial knee replacement is better than a total knee replacement, when conditions allow it, particularly in older patients. Studies show that the partial knee replacement improves the functioning of the knee in a better way than the total replacement.
Partial knee replacement results in less blood loss and trauma. The medical and surgical complications are also less with this surgery. Patients with arthritic knees are candidates for partial knee replacement.
Partial knee replacement preserves the range of motion because it keeps any healthy tissue and bone in the knee. Since less blood is lost during the surgical treatment, the patient recovers faster.
Recovery is quick with a partial knee replacement; the patient can start moving the knee the day after the surgery. Most patients also work with a physical therapist while in the hospital and then for two to four weeks as an outpatient.
If you take care of your knee by visiting physical therapist regularly, you will be able to walk in about six to eight weeks.
