Total and Partial Knee Replacement Surgery

A Minimally Invasive Approach to Knee Replacement Surgery

The knee joint is a critical structure that bears much of the body’s weight and enables a wide range of motion, including walking, running, and jumping. Comprised of the femur (thigh bone), tibia (shin bone), and patella (kneecap), the knee joint is cushioned by cartilage and stabilized by ligaments. Over time, various conditions such as osteoarthritis, rheumatoid arthritis, or traumatic injuries can damage the cartilage, leading to pain, swelling, and reduced mobility. When these symptoms become severe and do not respond to conservative treatments, knee replacement surgery may be necessary to restore function and alleviate pain.

Dr. Alex Sweet is a highly skilled knee specialist with extensive experience in performing both total and partial knee replacement using minimally invasive techniques, such as augmented reality robotic surgery. Practicing at Louisville Orthopaedic Clinic’s locations in Louisville, KY, and New Albany, IN, Dr. Sweet offers cutting-edge surgical options designed to enhance recovery and improve the overall quality of life for patients suffering from debilitating knee conditions.

Augmented Reality Robotic Total Knee Replacement Surgery

Minimally invasive robotic total knee replacement surgery is a highly advanced procedure utilizing cutting-edge technology designed to replace the damaged knee joint with an artificial implant while preserving as much of the surrounding tissue as possible. Unlike traditional knee replacement surgeries, which involve large incisions and significant disruption of the quadriceps muscle, minimally invasive techniques use smaller incisions and specialized instruments to access the joint. This approach reduces trauma to the muscles and tendons, leading to a quicker recovery and less post-operative pain.

During the surgery, Dr. Sweet carefully removes the damaged cartilage and bone from the knee joint and replaces it with a prosthesis designed to replicate the natural movement of the knee. The use of augmented reality robotic technology allows for precise placement of the implant, which is crucial for achieving optimal alignment and long-term function. Patients who undergo minimally invasive total knee replacement surgery typically experience faster rehabilitation, with many returning to normal activities within a few weeks.

Partial Knee Replacement Surgery

Minimally invasive partial knee replacement surgery is an excellent option for patients whose knee damage is confined to a single compartment, such as the medial (inside) or lateral (outside) part of the knee. This procedure involves replacing only the damaged portion of the knee joint with a custom-fitted prosthesis while preserving the healthy cartilage, ligaments, and bone. By maintaining the natural structure of the knee, this surgery allows for a more natural feeling post-operatively and quicker recovery.

The benefits of this approach include smaller incisions, less post-operative pain, and a faster return to activities. Partial knee replacement is particularly beneficial for active patients who wish to maintain a high level of physical activity after surgery. However, this procedure is only appropriate when the damage is limited to a specific area.

Am I a Candidate for Knee Replacement Surgery?

Knee replacement surgery is typically considered when conservative treatments such as medication, physical therapy, or injections fail to relieve severe knee pain caused by injury or degenerative disease. Patients who experience chronic knee pain that interferes with daily activities, such as walking, climbing stairs, or sleeping, may be candidates for either total or partial knee replacement surgery. The decision to proceed with surgery depends on various factors, including the extent of cartilage damage, the patient’s overall health, and the degree of pain and mobility limitation.

Total knee replacement is often recommended for patients with extensive cartilage loss affecting multiple areas of the knee joint, leading to significant pain and disability. On the other hand, partial knee replacement may be appropriate for those with damage limited to a specific compartment of the knee. Dr. Sweet thoroughly evaluates each patient’s condition, taking into account their medical history, lifestyle, and personal goals, before recommending the most suitable treatment option.

Rapid Recovery Outpatient Knee Surgery

In some cases, Dr. Sweet may recommend rapid recovery outpatient knee surgery, which allows patients to return home the same day as their procedure. This option is typically available for healthy individuals with a strong support system at home and minimal risk factors. Rapid recovery surgery is made possible through minimally invasive techniques, advanced pain management strategies, and a comprehensive post-operative care plan that begins immediately after surgery.

The advantages of outpatient knee surgery are numerous, including reduced hospital stays, lower risk of infection, and a more comfortable recovery environment at home. Early mobilization is key to a successful recovery, and patients are encouraged to begin physical therapy as soon as possible. By starting rehabilitation early, patients can regain strength, flexibility, and function more quickly, leading to better long-term outcomes.

Recovering From Knee Replacement Surgery

Recovery from knee replacement surgery varies depending on the type of procedure performed and the patient’s overall health. Most patients can expect to use a walker or crutches for the first few days to weeks following surgery, transitioning to a cane as they regain strength and balance. Physical therapy plays a critical role in recovery, focusing on restoring range of motion, strength, and function in the knee joint.

Your knee surgery will include a comprehensive post-operative care plan, including detailed instructions on wound care, pain management, and activity restrictions. Regular follow-up appointments ensure that the recovery is progressing as expected and allow for any necessary adjustments to the rehabilitation plan.

With dedication to physical therapy and adherence to post-operative guidelines, most patients can expect to return to their normal activities within a few months, with continued improvements in strength and mobility over the course of the first year.

"I was treated in the ER, on a Monday, for a patellar fracture. On Wednesday, the same week, I had an appt at Dr. Sweet II office. The next day he did surgery. I was very impressed and will recommend him to other people."

Amanda Y.

"Dr. Sweet II, Dr Compton, Katie and their staff are kind, caring and supportive. They have treated me with nothing less than the best care. They have helped me find myself again after suddenly losing my mobility and everything that goes along with it. After my first and second surgery, Dr. Sweet came out and sat with my underage, nervous, daughter and was so kind and caring as he told her that everything went well. He still asks about her during visits and she asks about him after I arrive home. He really made an impression on her and that, to me makes him the best."
