Hear from our patients.

Enjoy more pain-free days.

Chronic knee pain can interfere with work or play—but it doesn’t have to. If joint-related pain keeps you from doing what you love, visit a specialist in or around the Baltimore area to help relieve your symptoms, with or without surgery.

  • Reasons to See a Specialist

    MedStar Orthopaedic Institute experts diagnose and treat the full range of knee and joint conditions. We offer non-surgical, minimally invasive, and standard treatments for conditions that affect mobility, such as:

    • Arthritis
    • Avascular necrosis—temporary or permanent loss of blood supply to the bones in the knee
    • Generalized knee pain
    • Injuries with instability, swelling or pain

    With advanced imaging—and insights about your symptoms and goals—we can pinpoint the cause of your knee pain and recommend a treatment plan to help you enjoy more pain-free days.

  • Treatment Options

    Many patients find relief from knee pain without surgery. Our experts will discuss all your treatment options with you. Then, we will personalize your care plan based on your lifestyle, needs, and goals. For maximum pain management without surgery, we may recommend a combination of treatments such as:

    • Anti-inflammatory or pain medication
    • Arthroscopy to “clean up” damaged joint tissue
    • Corticosteroid or platelet-rich plasma (PRP) injections
    • Physical therapy
    • Radiofrequency ablation
    • Weight loss

    MedStar Orthopaedic Institute joint surgeons are experts in minimally invasive and traditional techniques. If you need knee surgery, we will help you understand what to expect before, during, and after your procedure. Using leading-edge robotic and image-guided technologies, we offer the full range of procedures, including:

    • Cementless knee replacement
    • Corrections or replacements of formerly replaced joints
    • Full and partial knee replacement
    • Outpatient knee replacement
    • Traditional and robotic-assisted surgery

    Renowned for surgical excellence, our specialists tend to the joint health of athletes who play for the Baltimore Ravens, Baltimore Orioles, Washington Wizards, Washington Capitals, and U.S. Lacrosse.

  • Robotic-Assisted Knee Replacement

    Innovative robotic technologies do not replace surgical expertise but do help us give you the most precise outcomes. Using the latest technology, our knee surgeons get a better view of your joint, bones, muscles, and nerves—allowing us to maneuver instruments with more accuracy than ever before.

    Watch our Facebook Live on robotics to learn more.

    Robotic-assisted knee replacement using the innovative MAKOplasty® or ROSA® systems require smaller incisions than traditional arthroplasty. Using 3D bone modeling and virtual implant templates based on your own imaging, we can size, align, and position your new knee joint to seamlessly match your anatomy.

    With precise, personalized planning, our expert surgeons can avoid disturbing healthy tissues around the joint as we correct the cause of your symptoms. The results?

    • Shorter hospital stay—or no stay required
    • Faster recovery
    • Lower risk of complications

    MedStar Orthopaedic Institute is one of the largest musculoskeletal robotic surgical programs on the east coast, with 10 robots for hip, knee, and spine surgery. Our center performed the first robotic-assisted total knee replacement surgery in Maryland, and our experienced surgeons have performed more than 1,500 robotic-assisted joint replacements to date.
