Questions

Before your first visit

What does Dr. McMillan treat?

Dr. McMillan treats sports-related injuries and conditions of the shoulder and hip, with select ankle care as well. At his Burlington Township, NJ practice, that includes muscle injuries and avulsions, arthritis of the hip, hip and thigh muscle strains and contusions, snapping hip (a hip joint that clicks or catches during movement), and lateral ankle instability (an ankle that repeatedly gives way after earlier sprains). He completed fellowship training in arthroscopic sports medicine of the shoulder, hip, knee, and elbow at the University of Massachusetts in Worcester, which shapes how he evaluates and treats these conditions.

Does Dr. McMillan perform shoulder replacement surgery?

Yes. Dr. McMillan performs reverse total shoulder replacement, a procedure that repositions the ball and socket of the shoulder joint for patients whose rotator cuff, the group of muscles and tendons that normally stabilize the shoulder, is too damaged to support a standard replacement. He also performs arthroscopic surgery of the shoulder, a technique that uses a small camera and thin instruments inserted through tiny incisions to diagnose and treat shoulder problems.

Will I need surgery for hip arthritis?

Not necessarily. Many patients with hip arthritis improve with non-surgical care first, such as activity changes, physical therapy, or injections, before surgery becomes part of the conversation. When those options stop relieving symptoms, Dr. McMillan discusses hip arthroscopy or another surgical approach based on how much joint damage is present.

Can a pulled hip or thigh muscle be treated without surgery?

Most can. Hip and thigh muscle strains and contusions, along with general muscle injuries and avulsions, usually respond to rest, physical therapy, and a structured return-to-activity plan. Dr. McMillan's background in sports medicine informs how that plan is built for athletes and active adults who want to return to activity safely.

Is a sprained ankle that will not heal something Dr. McMillan treats?

Yes, when it involves lateral ankle instability, a condition where the outer ligaments of the ankle no longer hold the joint steady after repeated sprains. Dr. McMillan treats this condition and, when surgery is needed, performs the Brostrum procedure, a ligament repair that restores stability to the outer ankle.
