Direct Anterior Hip Replacement

Though the direct anterior approach is a newer approach to hip replacement than more traditional approaches, it has been around for over 10 years, and long-term data shows great results for patients. With the direct anterior approach, Dr. Coen makes an incision at the front of the hip, which is a more “muscle-friendly” way to approach the hip. This may lead to less pain that can allow patients to progress more quickly in the initial recovery phases. The direct anterior approach also has fewer restrictions in the initial recovery phase.

Outpatient Hip & Knee Replacement

For many years, hip and knee replacements had to be done in hospitals because they are more complex procedures. However, advances in technology, instruments, and pain management have allowed us to perform hip and knee replacements in outpatient settings. Dr. Coen has performed outpatient hip and knee replacements for over 5 years and currently performs these procedures at a surgical center specifically designed for complex orthopedic procedures like joint replacements. Dr. Coen believes that outpatient hip and knee replacements offer several benefits for patients, including reduced infection risks, the ability to recover comfortably at home, and potential cost savings.

Partial Knee Replacement

Partial knee replacement can be a great option for patients with arthritis that is limited to a single segment, or compartment, of the knee. A partial knee replacement retains more of the patient’s own healthy bone and cartilage in the knee, replacing only the damaged portion of the knee. Dr. Coen typically recommends this option for younger, more active patients who have arthritis in a single compartment of the knee because it feels more natural than a total knee and has fewer activity restrictions.

Total Knee Replacement

If a patient has severe arthritis throughout the knee that has limited their daily activities, total knee replacement can improve knee mobility and reduce pain. With over 25 years of experience, Dr. Coen averages about 200-300 knee replacements every year. Surgical skill is very important to ensure accurate implant placement, but physical therapy and at-home exercises are critical to the patient’s overall outcomes and long-term function of the knee. Dr. Coen provides the necessary education and support to ensure that patients stick to the recovery plan to regain the range of motion and strength needed to return to all normal activities without pain.
