The Anterior Approach to hip replacement surgery allows the surgeon to reach the hip joint from the front of the hip as opposed to the lateral (side) or the posterior (back) approach. This way, the hip can be replaced without detachment of muscle from the pelvis or femur during surgery.

Subchondroplasty (SCP) is a minimally invasive treatment for defects in bone called bone marrow lesions. Bone marrow lesions represent the healing response to areas of insufficiency and micro fractures known to cause joint pain and accelerate joint damage. These lesions are often found within the knee joints. Bone marrow lesions can be diagnosed using magnetic resonance imaging (MRI). SCP treats bone marrow lesions in the knee joint by filling in the defects with an absorbable material. This material is then eventually resorbed and replaced with healthy bone. This procedure can be performed in 30-60 minutes in an out patient surgery center and patients can return home the same day of their surgery.

Unicompartmental knee replacement or partial knee replacement is a surgical procedure where only the damaged portion of the knee is replaced. There are three compartments of the knee. Depending on if your arthritis is confined to a single compartment of your knee will dictate whether you may be a good candidate. Advantages of the unicompartmental knee replacement are quicker recovery, less pain after surgery and less blood loss. In some cases, a unicompartmental knee replacement can be performed in an outpatient surgical suite and patients can return home the same day of their surgery.

Platelet rich plasma (abbreviated PRP) is a new treatment used for some common orthopedic conditions. PRP is a concentration of platelet cells taken from your blood, and these platelets have growth factors that may help in the healing process of chronic injuries. Growth factors are chemicals that signal the body to initiate a healing response. By injecting PRP into areas of an injury, the hope is to stimulate and optimize your body's ability to heal the chronic conditions such as knee arthritis, rotator cuff injuries, and tennis elbow.
