Minimally Invasive Partial Knee Arthroplasty

What is Minimally Invasive Partial Knee Arthroplasty?

Minimally Invasive Partial Knee Arthroplasty is a surgical procedure designed to replace only the damaged part of the knee joint, preserving as much of the natural knee as possible. This technique involves smaller incisions compared to traditional knee replacement surgery, leading to less tissue damage and quicker recovery times.

Indications for Minimally Invasive Partial Knee Arthroplasty

Minimally Invasive Partial Knee Arthroplasty is performed to relieve pain and restore function in patients with localized knee arthritis or damage. It is ideal for individuals whose arthritis is confined to a single compartment of the knee. This procedure helps maintain more of the knee's natural structure and function, offering a more natural feeling post-surgery.

Preparation for Minimally Invasive Partial Knee Arthroplasty

Preparation for the procedure involves a thorough medical evaluation, including imaging studies like X-rays or MRIs to assess the extent of knee damage. Patients may need to stop certain medications and follow specific preoperative instructions regarding diet and activity. Pre-surgical physical therapy may also be recommended to strengthen the muscles around the knee.

Minimally Invasive 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 affected area of the knee. Through this incision, the surgeon carefully removes the damaged bone and cartilage from the specific compartment of the knee that is affected by arthritis or injury using special instruments. This precise removal is crucial to prepare the area for the prosthetic component. The surgeon then fits a specially designed prosthetic implant into the knee, ensuring it aligns perfectly with the remaining natural structures to restore function and stability. After the implant is securely in place, the surgeon closes the incision with sutures or staples. The minimally invasive approach allows for less disruption to the surrounding tissues, which typically results in reduced postoperative pain and a quicker recovery time compared to traditional knee replacement surgery.

Recovery after Minimally Invasive Partial Knee Arthroplasty

Recovery typically involves a shorter hospital stay and a faster return to normal activities compared to traditional knee replacement. Physical therapy is crucial to regain strength and mobility. Most patients can resume daily activities within a few weeks, with full recovery taking a few months.

Risks of Minimally Invasive Partial Knee Arthroplasty

While the procedure is generally safe, potential risks include infection, blood clots, implant loosening, and nerve or blood vessel damage. There is also a possibility that the remaining parts of the knee may develop arthritis over time.

Benefits of Minimally Invasive Partial Knee Arthroplasty

The benefits of the procedure include smaller incisions, reduced pain, quicker recovery, and preservation of more natural knee function. Patients often experience less postoperative discomfort and a faster return to their daily activities.
