Robotic Assisted Total Knee Replacement

Total knee replacement (TKR) and partial knee replacement surgery is considered for painful osteoarthritis of the knee when non-operative treatment fails to control the patient’s symptoms. Knee replacement surgery involves resurfacing the damaged arthritic surfaces with implants typically made of metal alloys and strong plastic (polyethylene).

The knee has three compartments – medial (inside), lateral (outside), and patellofemoral (kneecap). Partial knee replacement is performed when only one of the knee compartments is arthritic. A total knee replacement is performed when 2 or more of the knee compartments are arthritic.

Robotic-assisted TKR and partial knee replacement provides a precise customized plan based on a preoperative CT scan. The CT scan is combined with real time navigation of the patient’s specific bone anatomy during surgery to provide accurate and consistent implant size and position. Ideal implant size and position leads to better function and longer lasting joint replacement.

The robotic arm is controlled by the surgeon and works in a predefined area based on the patient’s personalized pre-operative plan. If the robotic arm strays, it stops working, protecting surrounding tissues. Fine-tuned adjustments can be made during surgery based on real-time feedback provided by the computer navigation screens.

Robotic-assisted TKR and partial knee replacement is believed to provide improved precision of implant position and size leading to better function and longevity of the knee replacement.

 

 

 

 

Robotic Assisted Total Hip Replacement

Total hip replacement (THR) and is considered for painful osteoarthritis of the hip when non-operative treatment fails to control the patient’s symptoms. Hip replacement surgery involves resurfacing the damaged arthritic surfaces with implants typically made of metal alloys and strong plastic (polyethylene).

The hip is a ball and socket joint. The socket (acetabulum) is replaced with a metal cup. The polyethylene is inserted into the metal cup to allow for a smooth gliding surface. The ball is replaced with a metal stem inserted into the femoral canal (thigh bone). A metal or ceramic ball is attached to the stem.

Robotic-assisted THR provides a precise customized plan based on a preoperative CT scan. The CT scan is combined with real time navigation of the patient’s specific bone anatomy during surgery to provide accurate and consistent implant size and position. Ideal implant size and position leads to better function and longer lasting joint replacement.

Robotic-assisted THR is believed to provide improved precision of implant position and size leading to better function and longevity of the hip replacement.

Richard S. Howell, M.D.

Dr. Richard Howell is a Fellowship trained Orthopaedic Surgeon specializing in Sports Injuries and Surgery, Shoulder Surgery, and Hip Arthroscopy. His clinical interests include Shoulder Dislocations and Labral Tears, Rotator Cuff Tears, Shoulder Arthritis and Arthroplasty (Joint Replacement), Anterior Cruciate Ligament (ACL) tears, Multiple Ligament Knee Injuries, Meniscus Tears, Cartilage Damage, Hip Labral Tears, Femoroacetabular Impingement, and Joint Preservation.

Dr. Howell is a native of Carlisle, Pennsylvania. He attended Messiah College in Grantham, Pennsylvania and earned a Bachelor’s degree, graduating Magna Cum Laude. He went on to receive his Medical Doctorate from Drexel University College of Medicine in Philadelphia where he was also inducted into the medical honors society. Following medical school, Dr. Howell remained at Drexel University for five years of orthopaedic surgery residency training with extensive experience in joint replacement and trauma surgery. He was selected as Chief Resident during his final year. He then completed a fellowship in Sports Surgery at University of Chicago Pritzker School of Medicine. His fellowship encompassed all areas of sports surgery, in addition to an emphasis on shoulder replacement and hip arthroscopy.

Dr. Howell has published manuscripts in peer-reviewed scientific journals on the subjects of meniscus injury, nerve blocks for knee surgery, and spine column injuries. He has presented his research at orthopaedic meetings and frequently gives lectures to train other surgeons.

He served as Team Physician for the Chinese National Olympic Men’s and Women’s Volleyball teams, Women’s NBA Chicago Sky, University of Chicago, and Concordia University.

In his free time, Dr. Howell enjoys running, golf, hunting, attending sports events, and being on the water. His wife, Marta, is a native Floridian. Together they enjoy traveling, hiking, and anything outdoors.
