David J. King, MDOrthopaedic Surgeon
David J. King, MD

A Leader in Sports Medicine, Hip, Knee and Shoulder Surgery, and The Care of the Injured Worker

Dr. King was raised in Atlanta, Georgia. He attended the University of Virginia where he received a Bachelor of Arts in 1997 as an honors major in neuroscience. He received his medical degree from Emory University School of Medicine in Atlanta, Georgia in 2001. Dr. King completed a five-year residency in orthopaedic surgery at Washington University School of Medicine/ Barnes-Jewish Hospital in St. Louis, Missouri.

Dr. King completed a sports medicine fellowship at the Steadman Hawkins Clinic in Vail, Colorado. His fellowship focused on the treatment of injuries to the shoulder, elbow and knee, with a special emphasis on arthroscopic treatment of hip impingement, labral tears, cartilage injuries and other abnormalities. He spent extensive time training with Dr. Marc Philippon, a pioneer in hip arthroscopy. While in Vail, Dr. King provided care for the United States Ski and Snowboard teams. In addition, he performed hip arthroscopy on numerous professional athletes in the NFL, Premier Soccer League and NHL.

Dr. King has extensive and specialized training in orthopaedic surgery, sports medicine, and hip arthroscopy. His emphasis is on arthroscopic and open surgery of the hip, shoulder, elbow and knee. Dr. King has a unique interest in arthroscopic treatment of hip pathology that may one day be shown to prevent or delay the onset of hip arthritis in adolescent, young adult and adult hips. He addresses hip impingement and labral tears with arthroscopic labral repair, using bioabsorbable bone anchors similar to those used in shoulder surgery. He also removes the bony abnormalities associated with this condition entirely through the arthroscope. Dr. King also performs total joint replacement for patients with advanced hip arthritis that cannot be treated with arthroscopy.

Dr. King recently served as an Associate Master Instructor at the AANA Hip Arthroscopy Course in Chicago. He was involved in teaching and instructing other board certified orthopaedic surgeons in the techniques of hip arthroscopy and hip labral repair.

Throughout his academic career, Dr. King has had substantial involvement in orthopaedic research. Specific projects have focused on advances in hip arthroscopy, cartilage regeneration, shoulder replacement surgery and lower extremity deformity correction. His studies have been published in the Journal of Bone and Joint Surgery, Techniques in Sports Medicine and Techniques in Arthroplasty and also earned him the Leonard Marmor Foundation Award while at Washington University.

Does Dr. King treat other areas in addition to the hip?

Although Dr. King has a unique interest in treating hip injuries, he is fellowship trained in sports medicine to repair injuries of the shoulder, knee, elbow and ankle.

If I have an injury to my hip joint, where would it hurt?

Injuries to the hip joint cause pain in the groin, outside or lateral aspect of the hip and even in the buttocks. Unlike other joints in the body, such as the knee or elbow, the hip joint is deep in the pelvis. Due to the deep positioning of the joint, referred pain is often felt in multiple areas unique to each individual patient.

How did I “get” hip impingement (femoroacetabular impingement)?

We currently do not know the reason for the excess bone seen in the hip region with impingement. Although there are specific causes like slipped capital femoral epiphysis (SCFE), the majority of cases are felt to represent a lack of “remodeling” during the developmental years through adolescence.

If I have a hip labral tear and impingement, will I continue to damage my hip if I run, exercise and participate in sports without fixing it first?

The short answer is yes. The difficult issue is that we don’t know how quickly and to what extent patients will continue to damage the hip joint if they remain active prior to fixing a labral tear and impingement. The type of activity and intensity are important factors. In general, I tell patients to “use pain as their guide.” Activities that cause more pain, may be causing more damage. As far as time, I recommend fixing these injuries within 3 months of diagnosis. If patients wait 4-6 months or longer, I recommend re-evaluation with X-rays to ensure that arthritis has not developed. Read More

How do I know if I am a candidate for hip arthroscopy?

Dr. King will provide a free evaluation of a patient’s X-ray and MRIs to see if an office visit and examination are appropriate when a patient is considering hip arthroscopy. Often X-rays and/or MRIs will show advanced arthritis in the joint making hip arthroscopy a poor treatment choice. Because many patients travel long distances and multiple states to be evaluated, this service is intended for patients outside of the St. Louis area.

How much physical therapy will I need after surgery?

Dr. King believes very strongly in the need for appropriate physical therapy after injuries and surgical procedures. Each patient has unique needs and will have established therapy protocols modified by Dr King for their individual needs. The number of visits required is directly related to a patient’s improvement and return of function.

How do I schedule an appointment with Dr. King?

The best way to schedule an appointment is to call the main number, (314) 991-2113, and follow the directions to reach Dr. King’s personal scheduler. It may take a few menus before you are connected to a live scheduler, but you will always be able to talk to a person and will not have to leave messages.
