Joint Replacement Surgery with Dr. Harwin


As an orthopaedic specialist, Dr. Harwin believes that a key part of his responsibility is to help each patient make his or her own informed decision about treatment options and whether or not to have joint replacement surgery.

When Dr. Harwin does recommend surgery, it is only after nonsurgical options have been considered. Patients are shown educational materials, including anatomical models and brochures, to help them understand the surgical procedure and potential outcomes, including benefits, risks and alternatives.

Patients who elect to have surgery will take comfort in knowing they are in the hands of one of the most experienced orthopaedic surgeons in the nation. During his career, Dr. Harwin has performed over 12,000 total hip and knee replacement procedures.

Knee Replacement Surgery

Dr. Harwin is experienced in many different approaches and techniques for knee replacement surgery. He works with his patients to determine the best knee replacement option based on needs and lifestyle. Learn more about knee replacement surgery with Dr. Harwin in the topics below.

Total Knee Replacement

Total knee replacement is a common procedure used to treat knee arthritis. During this procedure, Dr. Harwin replaces the damaged surfaces of knee joint with prosthetic components that mimic the feel and motion of a natural knee. This can provide significant pain relief and improved knee function for patients. Dr. Harwin also offers custom-designed gender-specific knee implants designed to conform closely to the differing bone profiles of male and female patients.

Knee Resurfacing

Knee resurfacing, also known as a partial knee replacement, may be an option for patients with arthritis damage that is limited to only one section of the knee. This procedure allows Dr. Harwin to preserve as much of the patient’s natural bone as possible. This procedure is typically recommended for younger patients who may need a total knee replacement later in life.

Asian Knee Replacement

Many patients of Asian descent come from cultures where kneeling or sitting upright on the floor is common for dining, meditation, or formal events. This requires a great deal of knee flexion, which can lead to knee arthritis. Dr. Harwin offers knee replacements for these patients that allow for enough flexion in the knee to be able to kneel or sit on the floor after surgery.

Hip Resurfacing

Hip resurfacing may be another option for patients with hip arthritis. Hip resurfacing is still considered a total hip replacement, but less bone is removed during the procedure. This may lead to a wider range of motion and lower risk of dislocation.

Anterior Hip Surgery

Dr. Harwin also utilizes minimally invasive approaches to hip replacement surgery, including the direct anterior and direct anterior-lateral approaches. With these approaches, the incision is made at the front or side of the hip, rather than the back. These approaches allow Dr. Harwin to make smaller incisions and disturb fewer muscles and tendons, which may lead to quicker recovery.

Ceramic Hip Replacements

In addition to the traditional metal hip replacement implants, Dr. Harwin also uses ceramic hip implants where appropriate. Ceramic hip replacement implants may be a better alternative for younger patients, as they may last longer than the metal hip replacement implants. Ceramic implants may last longer, helping to reduce the need for revision hip replacement in the future.

Dr. Harwin is always seeking to improve results for his patients, and has assisted in the design of joint replacement implants. The MDM® (Modular Dual Mobility) system is one of the implants that Dr. Harwin helped design. MDM® hip replacement implants are designed to improve joint replacement stability, so that active patients can engage in recreational and sports activities.

Robotic Assisted Joint Replacement Surgery

Dr. Harwin offers robotic-assisted hip and knee replacements using Mako™ Robotic-Arm technology. Mako™ Robotic-Arm technology offers many benefits over traditional surgical methods and can be helpful in restoring mobility for patients suffering from arthritis in the hip or knee that has not responded to nonsurgical treatments.

Revision Joint Replacement

A small percentage of patients who receive joint replacements will need a revision joint replacement. Revision joint replacements may be recommended due to an infection after the initial joint replacement, hip injuries, or wear on the hip implants over time. During this procedure, the original implants are removed and replaced with new implants to restore joint function.
