Understanding Knee Pain — Causes, Symptoms & When to See a Doctor
Knee pain is one of the most common orthopedic conditions, affecting people of all ages and activity levels. Whether caused by an injury, arthritis, or overuse, knee pain can limit movement, impact daily life, and make even simple activities uncomfortable.
At OrthoBethesda, with locations in Bethesda, MD and Tysons, VA, our orthopedic knee specialists help patients find relief through accurate diagnosis, personalized care, and the latest treatment options — from physical therapy to advanced surgical solutions.
Common Causes of Knee Pain
Many factors can contribute to knee pain. The most common include:
- Arthritis: Joint inflammation that causes stiffness and swelling.
- Ligament injuries: Tears of the ACL, MCL, or other stabilizing ligaments from sports or trauma.
- Meniscus tears: Damage to the cartilage that cushions your knee joint.
- Tendonitis: Inflammation of tendons from repetitive strain.
- Bursitis: Swelling of small fluid-filled sacs (bursae) that cushion the joint.
- Patellar conditions: Problems with the kneecap such as misalignment or chondromalacia patella.
- Cysts and inflammation: Such as Baker’s cysts or plica syndrome, which cause swelling behind or inside the knee.
- Gout and metabolic conditions: Crystal buildup in the joint causing pain and redness.
Tip: Early evaluation helps prevent worsening damage and can reduce the need for surgery.
Symptoms That Shouldn’t Be Ignored
You should see an orthopedic knee specialist if you experience:
- Pain that lasts more than a few days
- Swelling, redness, or warmth around the joint
- Clicking, locking, or grinding sounds
- Difficulty bending, straightening, or bearing weight
- Instability or the feeling that your knee might “give out”
Our fellowship-trained orthopedic surgeons and sports medicine physicians in Bethesda and Tysons can determine the cause and recommend the most effective treatment plan.
Diagnosing the Cause of Knee Pain
A thorough evaluation includes:
- Medical history & physical exam
- Diagnostic imaging: X-rays, MRI, CT, or ultrasound
- Lab tests: To identify gout, infection, or inflammatory arthritis
- Arthrocentesis: Removing and testing fluid from the knee joint if needed
At OrthoBethesda, we use advanced imaging and precision diagnostics to identify the cause of your pain and build a treatment plan tailored to your lifestyle.
Treatment Options for Knee Pain
Treatment depends on the underlying cause. Our team prioritizes non-surgical solutions whenever possible, such as:
Conservative Care:
- Rest, ice, compression, and elevation (RICE)
- Physical therapy to strengthen muscles and restore motion
- Bracing or activity modification
- Anti-inflammatory medication or injections
Minimally Invasive Options:
- Knee arthroscopy: To repair meniscus tears or remove damaged tissue
- Image-guided injections: Cortisone or viscosupplementation for inflammation and joint lubrication
Surgical Care:
When advanced arthritis or ligament damage limits function, our surgeons offer:
- Partial and total knee replacement
- Robotic-assisted procedures for improved precision and faster recovery
When Knee Pain Requires Urgent Evaluation
- Seek immediate care if you notice:
- Inability to walk or bear weight
- Visible deformity or sudden swelling
- Severe pain following an injury
- Signs of infection (fever, redness, warmth)
- Early diagnosis can prevent long-term complications and preserve your joint health.
