Custom-fitted Partial Knee Arthroplasty
What is Custom-fitted Partial Knee Arthroplasty?
Custom-fitted Partial Knee Arthroplasty is a surgical procedure designed to replace only the damaged portion of the knee joint with a prosthetic implant that is tailored specifically to the patient's anatomy. Unlike total knee replacement, this procedure preserves healthy bone and tissue, offering a more targeted approach to treating knee osteoarthritis or localized knee damage. The custom-fit design ensures that the implant conforms precisely to the patient’s unique bone structure, allowing for improved alignment, fit, and function.
Indications for Custom-fitted Partial Knee Arthroplasty
Custom-fitted Partial Knee Arthroplasty is performed to relieve pain and restore function in patients with knee osteoarthritis or damage that is confined to a specific area of the knee. It is an ideal option for individuals who have not found relief from conservative treatments like physical therapy, medication, or injections. By targeting only the affected part of the knee, this procedure allows for a quicker recovery, reduced pain, and a more natural-feeling joint post-surgery.
Preparation for Custom-fitted Partial Knee Arthroplasty
Preparation for this procedure involves a thorough evaluation by an orthopedic surgeon, including imaging tests such as X-rays, MRIs, or CT scans to assess the extent of the knee damage. These images are used to create a 3D model of the knee, which helps in designing the custom-fit implant. Patients may be advised to stop certain medications and should follow pre-surgical instructions, such as fasting or arranging transportation home after the surgery.
Custom-fitted Partial Knee Arthroplasty Procedure
Either regional or general anesthesia is administered to ensure the patient is comfortable and pain-free during the procedure. Once the anesthesia takes effect, the surgeon makes a small incision over the knee to access the damaged area. Using specialized tools and the 3D model, the surgeon carefully removes the damaged cartilage and bone. The custom-fitted implant is then placed into the joint, ensuring a precise fit. The incision is closed with sutures or staples, and the knee is bandaged. The procedure typically takes one to two hours.
Recovery after Custom-fitted Partial Knee Arthroplasty
Recovery from custom-fitted partial knee arthroplasty is generally quicker than total knee replacement. Most patients can start walking with assistance within a day of surgery. Physical therapy is crucial during the recovery period to restore strength, flexibility, and range of motion in the knee. Full recovery typically takes 4 to 6 weeks, with most patients returning to normal activities, including low-impact sports.
Risks of Custom-fitted Partial Knee Arthroplasty
As with any surgical procedure, there are risks associated with custom-fitted partial knee arthroplasty. These may include infection, blood clots, implant loosening, or an adverse reaction to anesthesia. In some cases, the remaining healthy knee tissue may develop arthritis, potentially requiring further surgery in the future.
Benefits of Custom-fitted Partial Knee Arthroplasty
The benefits of custom-fitted partial knee arthroplasty include a more natural joint feel, less postoperative pain, quicker recovery time, and preservation of healthy bone and tissue. The custom-fit design ensures better alignment and function of the knee, leading to improved patient satisfaction and long-term outcomes.
