Our Summary

This research paper discusses a study that was conducted on a specific type of knee replacement surgery for patients who have arthritis in two compartments of their knee (bicompartmental osteoarthritis). This procedure uses customized surgical tools and implants, made to fit each patient’s unique knee anatomy.

The study focused on patients with severe arthritis that had affected both the inner or outer, and kneecap compartments of their knee, and who had not found relief from non-surgical treatments or less invasive surgeries. The procedure is not recommended for patients with arthritis in all three knee compartments, those with unstable knee ligaments, those with severe knee deformities, or those who are severely overweight or have had certain prior knee procedures.

The surgical technique includes making an incision in the skin, identifying the area of the knee that is still functioning, removing damaged cartilage and bone growths, and balancing the knee with the help of custom-made tools. The surgeon then prepares the knee for the implant, which is put in place and secured with a special cement. After surgery, patients are encouraged to move their knee as much as they are able and to gradually increase their weight-bearing on the knee over a two-week period.

The results of this study showed that the procedure was successful in 44 patients, with only a few needing further surgery due to the implant becoming loose or needing additional work on the kneecap. The fit of the implant was found to be excellent in X-ray examinations. Patients also reported significant reduction in pain and improvement in their ability to do daily activities after surgery.

Doctor’s Tip

One helpful tip for patients undergoing knee replacement surgery is to follow your doctor’s post-operative instructions carefully. This may include physical therapy exercises, monitoring for signs of infection, and gradually increasing your activity level as directed. It is important to communicate with your healthcare team about any concerns or changes in your recovery process. By following these guidelines, you can help ensure a successful outcome and a smoother recovery process.

Suitable For

In general, patients who are typically recommended for knee replacement surgery include those with severe arthritis that has not responded to non-surgical treatments, those with significant pain and limited mobility in their knee, and those who have difficulty performing daily activities due to their knee pain. Additionally, patients who have arthritis in multiple compartments of the knee, like those with bicompartmental osteoarthritis, may be recommended for customized knee replacement surgery.

It is important for patients to consult with their healthcare provider to determine if knee replacement surgery is the best option for their individual case, and to discuss the potential risks and benefits of the procedure. Additionally, patients should be aware of the rehabilitation process and commit to following their surgeon’s post-operative instructions to ensure a successful recovery.

Timeline

Before knee replacement surgery, a patient typically experiences chronic pain, stiffness, and limited mobility in the affected knee. They may have tried various non-surgical treatments such as physical therapy, medication, and injections with little to no relief. They may also have difficulty performing daily activities and have a decreased quality of life due to their knee arthritis.

After knee replacement surgery, patients typically experience some pain and discomfort, which is managed with medication. They begin physical therapy to regain strength, flexibility, and range of motion in their new knee. Over time, they gradually increase their activity level and work on improving their walking and balance. Most patients report a significant reduction in pain and improvement in their overall quality of life following knee replacement surgery.

  3. How long is the recovery process and what can I expect in terms of pain and mobility during this time?
  4. Will I need physical therapy after surgery and how long will it last?
  5. How long will the implant last and are there any restrictions on physical activity or lifestyle changes I need to make?
  6. What is the success rate of this procedure and what are the potential outcomes I can expect?
  7. Will I need any additional surgeries or treatments in the future?
  8. What is the expected timeline for returning to work or normal activities after surgery?
