Many patients express interest in minimally invasive approaches to hip and knee surgery. I believe that this type of surgery, though technically challenging, offers many benefits to the patient, including less tissue injury, less post-operative pain, faster rehabilitation, and a shorter hospital stay.

The 2-incision hip replacement technique is a new approach to a well-established procedure. It involves minimal dissection of muscles, and no detachment of muscles from the bone. It is performed with x-ray guidance to assure appropriate placement of components. The first incision is made in the front of the hip, and measures about 5 cm (2 inches) in length. This allows placement of the socket component in the pelvis. Once this has been done, a second incision is made in the buttock, measuring about 3 cm (1-1/2 inches). The femoral component is placed through this incision. Again, x-ray guidance is used to assure proper placement of the prosthesis.

The lack of extensive dissection, and the ability to maintain muscle attachments, allows for rapid recovery. Typically, patients can be sent home from the hospital within 48 hours, and some can go home the same day. In addition, the two-incision technique allows for immediate weightbearing. A standard hip replacement approach requires a recovery period of about 12 weeks; the two-incision approach often reduces this to less than four. Although these procedures may not be appropriate for every patient, Dr. Manner is able to do them for most patients undergoing hip replacement.

Total knee replacement has traditionally been associated with a prolonged recovery and rehabilitation period. New developments in preparation and placement of implants allow preservation of muscle attachments. The incision is smaller than for a traditional approach, and is generally about 10cm (4 inches.) The dissection avoids the quadriceps, or thigh muscle, but allows for the placement of standard, well-tested components. In addition, computer guidance is a promising approach which helps provide proper alignment.

My major interests relate to the care and treatment of osteoarthritis. My aim is to conduct clinical research that has a significant impact on the field while raising the clinical standards for optimal patient care. I want to reduce morbidity and improve outcomes in these patients not only through research but also by establishing a model of care that can be universally applied, easily adapted to both academic and community groups and led by outstanding trainees who can influence care throughout the world.

1. Improve our understanding of cartilage biology, in particular the role of artificial matrix constructs to replace or augment diseased cartilage,
2. Apply this understanding to development of new treatments relevant to joint diseases, and
3. Introduce new techniques into clinical use, thus translating laboratory findings into practical treatment for life-impairing joint disorders.
