Which Doctor Treats Knee Pain?

Medically reviewed by Dr. Alex Movshis, MD Last reviewed March 2026

Knee pain is discomfort, aching, or stiffness in the knee joint. It can result from injury, wear and tear, or underlying conditions affecting the joint cartilage.

Knee pain is a common complaint that can affect anyone, from athletes to office workers. The knee is a complex joint that bears significant weight and stress during daily activities, making it vulnerable to injury and wear. Pain in the knee can stem from many causes including acute injuries like ligament sprains or meniscus tears, chronic conditions like arthritis, or overuse problems from repetitive activities. Knowing what kind of doctor should I see for knee pain is essential for proper diagnosis and effective treatment.

Your primary care physician is typically the best starting point for knee pain evaluation. They can perform basic assessments and determine whether you need specialist care. For sports-related injuries or acute knee problems, a sports medicine physician can provide specialized care focused on quick recovery and return to activity. If you have significant structural damage, arthritis, or need surgical evaluation, an orthopedic surgeon specializes in knee conditions and can offer both surgical and non-surgical options. Physical medicine and rehabilitation specialists focus on recovery through therapy and functional restoration, helping you regain strength and mobility.

The approach to knee pain depends on the underlying cause and severity of your symptoms. Many knee problems respond well to rest, ice, physical therapy, and activity modification. However, if you experience persistent pain, significant swelling, instability, or if your knee gives way, seeking prompt specialist evaluation is crucial for preventing long-term complications.
