Under severe degeneration of knee joint, it becomes essential to use minimally invasive treatment methods. An invasive method can complicate the knee condition. This method involves replacing diseased cartilage and bone with artificial materials. Being non-invasive, it uses a smaller incision than in traditional knee replacement procedure. As a result, it has many advantages. Advantages include short hospital stay, fast recovery and less scarring. This new less-invasive approach is sometimes also called quadriceps-sparing method.
The doctor initially evaluates the severity in the condition of patients knee. In severe knee condition, the doctor opts for a minimally invasive knee replacement technique. Prior to surgery, required amount of anesthesia is given to the patient. During surgery, a very small cut is made in the knee compared to traditional replacement surgery. Artificial implants are inserted through this incision. The tendons and ligaments in the path of artificial joints are properly aligned. The damaged bone is then removed and replaced with artificial joint. Proper stitches or sutures are used to cover the incision. A small tube is also sometimes placed at the knee to collect the draining out blood. Bandages are applied over the wound.
A one night stay is hospital is required after surgery for observation. In post-operation period, a splint or brace is kept in the knee. It protects knee from any injury. Also they are helpful to hold the knee in proper position. A rehabilitation program is encouraged for the patient to regain the overall health. It mainly emphasize on exercises which strengthens knee muscles and improve movement. Regular round of check-up with the doctor is necessary to maintain the knee stability. The knee recovers completely within 3-4 months.
Although this method involves many advantages but it also consists of some risks:
- Deformities in shape of knee
- Injured nerves or ligaments
- Excessive bleeding
- Increased pain and swelling
