Texas Hip and Knee Center

Dr. Steven B. Ogden, MD will be joining the practice on August 1, 2008 after completing a one year fellowship with Texas Hip & Knee Center.

Alternative Bearing Surfaces in Total Hip Arthroplasty
The most proven bearing surface in total hip replacement consists of a metal ball (femoral head) and plastic (high molecular weight polyethylene). There are now newer materials that wear much less than traditional plastic. These implants consist of highly cross-linked polyethylene, ceramics, or metal on metal. Our doctor and you can determine which bearing surface is best. Each surface has various risks and benefits.

Cartilage Restoration
There are now new techniques that allow your surgeon to restore damaged cartilage in the knee. Arthritis affecting the entire joint typically cannot be restored with today's techniques. However, isolated injuries can be treated with new surgeries that restore damaged cartilage in the knee. The techniques utilized include osteochondral autologous graft transplantation (OATS), allograft transplantation, and cell harvesting and cartilage growth.

The OATS procedure consists of transplanting bone and cartilage from non-weightbearing areas of the knee to areas on the joint surface where damage is present. This is typically done with arthroscopic surgery. Allograft transplantation consists of transplanting cadaver (donor matched) cartilage and bone to large defects on the knee joint surface. Cell harvesting and transplantation entails harvesting cartilage cells from the knee joint, multiplying the cells in the lab, and then during another surgery the cells are transplanted to areas of cartilage damage in the knee. Each technique has limitations and each patients options are different. Research is currently underway to determine new medicines, vitamins, or surgical procedures to protect and restore cartilage.

MIS "mini incision" Total Hip and Knee Surgery
More than 30 million people in the United States suffer from osteoarthritis. There are now new and exciting procedures using clinically proven implants for total hip and knee surgery. The implants are inserted through smaller incisions, which are typically 2-5 inches in length rather than the standard 10-12 inch incisions. Mini incision hip and knee replacement is a less invasive alternative to traditional joint surgery. It involves smaller incisions with specialized instruments.

We have noticed a faster rehabilitation and a shorter hospital stay in the majority of patients utilizing these new procedures. Some of our patients have been discharged from the hospital after 24 hours. These benefits may allow a faster return to work and daily activities. The minimally invasive technique may offer significant advantages over traditional hip replacement.

The Texas Hip and Knee Center has performed this surgery on patients as young as 36 years of age to patients in their 70's. However, the majority of patients undergoing this procedure are age 55 and older.

Our doctor and you can determine if you are a candidate for this procedure. A number of factors determine whether or not a patient is qualified to undergo the MIS procedure. An ideal candidate is someone who has osteoarthritis of the hip or knee and is in excellent health and fairly active. Candidates may also include people who are not responding to other forms of treatment, such as medication or therapy.

The Texas Hip and Knee Center in Fort Worth, Texas, has performed more two-incision total hip and mini-total knee replacements than any other site in Texas. Additionally, the surgeons at The Texas Hip and Knee Center routinely teach these new techniques to other physicians from around the region and work to develop and improve the techniques and the implants utilized.
