Unicompartmental knee replacement for pain relief from osteoarthritis in Mumbai


Generally, osteoarthritis is a chronic degenerative disease. That is a disease which begins by striking a single compartment and then gradually involving the other compartments.
For this reason, the single-compartment prosthesis is an intervention that is often carried out in young people, who obviously have a lot of pain and wish to undergo surgery. It, therefore, happens that at the first orthopedic examination for your knee problem you are advised to have a partial prosthesis and that after a few years this type of surgery is no longer practicable, but the total prosthesis is recommended.

Dr. Sanjay Desai is the best knee replacement surgeon in Mumbai. He has 28 years of experience in orthopedic surgery and works at Nanavati Super Specialty Hospital in Mumbai. Cost of partial knee replacement in India begins from USD 4000, including hospital stay for five days.

Benefits of Single-compartment Knee Prosthesis

Multiple studies have shown that modern single-compartment knee prosthesis perform very well in most patients where the indication to perform this surgery was correct.
The advantages of the single-knee prosthesis in the knee compared to total prosthesis include -
·         Smaller incision and surgical aggression since it is minimally invasive.
·         Less blood loss during surgery.
·         Less pain after surgery.
·         Faster recovery.
Furthermore, since the bone, cartilage and ligaments in the healthy parts of the knee are not sacrificed as is the case in the total prosthesis, most patients report that single-compartment knee prosthesis is perceived as more "natural" than a prosthesis total. Furthermore, a knee with the unicompartmental prosthesis can bend better.

Another fundamental advantage of this intervention for which it is particularly recommended in young people is that the replacement operation of the unicompartmental prosthesis (revision) that will be necessary when the implant will be worn out over time (on average 10-15 years) is definitely simpler and less risky than the total prosthesis replacement procedure.
The orthopedic doctor can advise you on surgery if you have an advanced form of osteoarthritis and have exhausted your non-surgical treatment options. Surgery should only be considered if your knee problem is significantly affecting your quality of life and interferes with normal daily activities.

To be an ideal candidate for this procedure, your osteoarthritis must be limited to one knee compartment, and your ligaments must be healthy.
Patients with rheumatoid arthritis, notable knee stiffness, axial deviations (knock knee or bowlegged) or with ligament damage are not ideal candidates for this type of surgery. An orthopedic surgeon will help you understand if this procedure is right for you. With a proper patient selection, modern unicompartmental knee prostheses have shown excellent medium and long-term results in both younger and older patients.

Surgical procedure

A partial knee replacement operation usually lasts an hour.
The surgeon will make a small incision in the front of the knee about 8 cm long. He will then verify that cartilage damage is, in fact, limited to one compartment only and that the ligaments are intact. If the surgeon finds that the situation is not suitable for partial knee replacement, he will perform a total knee replacement.

If the knee is suitable for partial knee replacement, the surgeon will use special saws to remove the cartilage from the damaged knee compartment and will bridge the ends of the femur and tibia with metal prosthetic coverings. The metal components are generally fixed to the bone with special cement. A plastic insert will be inserted between the two metal components to allow a smooth sliding surface.

Recovery phase

Because a partial knee replacement creates a small, less invasive incision, hospitalization is shorter and return to normal daily activities is rapid.
Patients have less postoperative pain and easier rehabilitation and in most cases, patients return home a few days after surgery.

Immediately after the operation, you can stretch the operated knee. You may need a walker or two crutches in the first few days until you develop the skill to walk without help.
A physiotherapist will give exercises that will help you maintain your freedom of movement and make the legs stronger.

It is very likely that the patient will resume normal life activities 8 weeks after surgery.
