Hip & Knee Pain
When pain or stiffness develops, whether from injury, arthritis, or overuse, it can significantly limit your ability to stay active and enjoy daily activities. At SOSI, we specialize in diagnosing and treating a wide range of hip and knee conditions—from early-stage joint pain to advanced arthritis. Our team is dedicated to helping patients preserve joint function through personalized treatment plans that may include physical therapy, injections, or, when necessary, joint replacement surgery. With the right care, it’s possible to reduce pain, restore movement, and get back to doing the things you love.
Knees
If you haven’t experienced a meniscus or ACL tear, chances are you know someone in Steamboat who has. These knee injuries often occur alongside a cartilage defect or tear.
“That’s the gliding surface of the knee—the surface we rely on for smooth weight-bearing,” says SOSI’s Dr. Alexander Meininger, who is fellowship-trained in sports orthopaedic surgery.
SOSI surgeons use advanced regenerative medicine tools such as platelet-rich plasma (PRP) or stem cell injections, as well as MACI surgery, which repairs cartilage defects in the knee.
Dr. Meininger, along with Drs. Adam Wilson and Michael Sisk, are SOSI’s primary knee specialists and experts.
Dr. Meininger performs more than 500 knee surgeries annually, about 150 of which are ACL repairs. Knees became a likely focus of his practice, thanks to sports-specific orthopaedic training. His love for the outdoors also led to a passion for taking care of athletic people.
“I’ve tried to develop my practice as a complex and advanced knee specialist, and also as an educator of arthroscopic surgery,” Dr. Meininger says.
When a knee replacement is necessary, SOSI’s subspecialty care means patients are in experienced hands.
Dr. Wilson says patients who get a knee replacement can get back to whatever activities they were enjoying before. Patients start walking on their new knee on the day of surgery.
“With a knee replacement, you can get back to normal activities within about three months, as opposed to an ACL, which is about six months,” Dr. Wilson says. “We’re pretty successful at getting people back to what they were doing.”

Hips
The hip joint is one of the largest joints in the human body with tremendous demands placed upon the ball and socket joint. As such its complex nature is prone to injury, strain, tearing or breakdown of the joint cartilage. Thankfully, we have a team of non-surgical, minimally invasive, and joint replacement specialists at SOSI to help you with any manner of hip problems.
Dr. Tyson Sloan is a board-certified Physical Medicine & Rehabilitation specialist who can often help discern the source of hip pain from the low back, sacroiliac (SI) joints or the hip joint ball and socket. He can also offer in-office injection therapy.
Dr. Jay Thompson is a fellowship-trained Orthopaedic Surgeon whose practice focuses on hip, shoulder, knee and sports medicine injuries. Dr. Thompson specializes in hip arthroscopy, hip preservation, hip reconstruction, lower extremity sports medicine, as well as hip and knee arthroplasty.
Joint preservation surgery through hip arthroscopy is an option for those with damage to the hip joint cartilage or the labrum. Outpatient, minimally invasive arthroscopic surgery serves to repair the torn cartilage and restore the hip joint before the onset of arthritis.
