Knee Injuries

At Orthopaedic Sports Specialists, Dr. Michael Joyce, Dr. Alex G. Dukas, and Dr. Christian A. Merrill provide comprehensive care for knee pain and injuries, from everyday aches to complex sports injuries. Our team takes an evidence-based, multidisciplinary approach, combining on-site X-ray and ultrasound imaging with physical therapy under one roof. Whenever possible, we prioritize non-surgical treatment — and when surgery is needed, our surgeons specialize in minimally invasive arthroscopic techniques designed to get you back to the activities you love as safely and quickly as possible.

Common Knee Conditions We Treat

ACL Tears A torn anterior cruciate ligament (ACL) is one of the most common serious knee injuries, especially in athletes who pivot, jump, or change direction quickly. We offer both non-surgical management and ACL reconstruction, tailored to your activity level and goals.

Meniscus Tears The meniscus cushions the knee joint, and tears are common from both sports injuries and everyday wear. Many meniscus tears respond well to physical therapy, while others benefit from minimally invasive arthroscopic repair.

Patellar Instability & Dislocation When the kneecap slips out of place or repeatedly feels unstable, it can limit activity and cause ongoing pain. We evaluate the underlying cause and build a treatment plan to restore stability.

Knee Osteoarthritis Wear-and-tear arthritis is a leading cause of chronic knee pain. We offer a full range of options, from injections and physical therapy to minimally invasive joint replacement when conservative care isn't enough.

Patellar Tendinitis ("Jumper's Knee") Common in athletes who jump or run frequently, this overuse injury responds well to targeted physical therapy and activity modification.

IT Band Syndrome A frequent source of outer-knee pain in runners and cyclists, typically treated through physical therapy, stretching, and activity adjustments.

MCL & LCL Sprains Ligament sprains on the inner or outer knee often result from direct contact or twisting injuries and are usually treated non-surgically with bracing and rehab.

Knee Bursitis Inflammation of the small fluid-filled sacs that cushion the knee joint, often caused by repetitive kneeling, overuse, or injury.

What to Expect at Your Visit

Treatment Options

During your first visit, one of our orthopedic surgeons will perform a thorough physical exam and review your symptoms and history. We have on-site X-ray and ultrasound imaging, so many diagnoses can be made the same day. If further imaging like an MRI is needed, we'll coordinate that promptly. Our goal is always to fully explain what's going on with your knee, your treatment options, and what recovery will look like — so you can make an informed decision about your care.

Non-Surgical Care

  • Physical therapy (on-site)

  • Bracing

  • Injections

  • Activity modification and guided rehabilitation

Surgical Care

  • Arthroscopic knee surgery

  • ACL reconstruction

  • Partial and total knee replacement (including minimally invasive techniques)

Every treatment plan is individualized. When surgery is recommended, our surgeons take the time to walk you through the procedure, expected recovery time, and post-operative protocols. Most surgeries are outpatient, and physical therapy typically begins within 1–3 days of the procedure.

Recovery & Physical Therapy

Our on-site physical therapy team works closely with our surgeons to build a coordinated recovery plan — starting before surgery, when applicable, and continuing through every stage of rehab. [Learn more about our Physical Therapy program →]

Post-operative protocols and instructions are also available in our [Patient Resources] section.

Frequently Asked Questions

How do I know if my knee pain needs surgery? Not all knee injuries require surgery. Many conditions, including some meniscus tears and early arthritis, respond well to physical therapy, bracing, or injections. Our surgeons will recommend surgery only when it's the best path to getting you back to your normal activities.

How long is recovery after ACL surgery? Recovery timelines vary by patient and procedure, but most patients begin physical therapy within days of surgery and follow a structured rehab program over several months. Your surgeon will give you a personalized timeline at your visit.

Can meniscus tears heal without surgery? Many meniscus tears, particularly smaller or degenerative tears, can improve significantly with physical therapy alone. Your surgeon will evaluate the size, location, and type of tear to determine the best approach.

When should I see an orthopedic doctor for knee pain? If knee pain persists more than a few days, limits your ability to walk or bear weight, or follows an injury with swelling or instability, it's a good time to be evaluated.
