Knee arthritis is a common condition that can severely impact mobility, joint function, and quality of life. Whether caused by degenerative joint disease like knee osteoarthritis, or inflammatory arthritis such as rheumatoid arthritis, early diagnosis and treatment are crucial to manage symptoms and slow progression.
At Rytel Sports Medicine, our team, led by Dr. Michael Rytel, works closely with patients to diagnose arthritis in the knee, assess the severity of joint damage, and tailor treatment options to reduce pain, preserve joint function, and protect long-term health.
In this guide, we explore how an orthopedic specialist identifies knee arthritis symptoms that need treatment, what diagnostic tools are used, and the best treatment strategies for each stage of arthritis.
Recognizing Early and Advanced Symptoms of Knee Arthritis
Knee arthritis symptoms can develop gradually or suddenly, depending on the cause and severity. Recognizing early signs allows patients to seek timely treatment and prevent further degeneration of the knee joint.
Early Symptoms
- Intermittent knee pain during or after physical activity, such as walking long distances, climbing stairs, or standing for extended periods.
- Stiffness in the morning or after rest, often lasting less than 30 minutes.
- Mild swelling around the knee, indicating irritation of the joint lining or soft tissues.
- Grating or crunching sensation (crepitus) during movement, reflecting wear on the articular cartilage.
- Reduced knee range of motion, especially after activity.
These symptoms may point to early-onset osteoarthritis or mild knee injury causing gradual cartilage wear.
Advanced Symptoms
- Persistent, severe pain even at rest or at night, interfering with sleep and daily activities.
- Severe joint stiffness that limits walking, bending, or weight-bearing activities.
- Visible deformity, such as knock knees or bow-legged posture, due to joint space narrowing or bone spurs.
- Joint instability, where the knee feels like it may give way.
- Muscle weakness and reduced ability to support body weight.
When knee arthritis symptoms reach these stages, orthopedic specialists may consider surgical interventions like total knee replacement surgery to restore function and relieve pain.
How Orthopedic Specialists Evaluate Knee Pain and Arthritis Symptoms
A detailed evaluation by an orthopedic specialist is essential for accurate diagnosis and treatment planning. The assessment includes:
Medical History
- Review of current knee pain, duration, intensity, and activities that trigger or worsen symptoms.
- Previous knee injuries, surgeries, or trauma.
- Personal or family history of rheumatoid arthritis or other autoimmune diseases.
- Discussion of lifestyle factors, including weight, physical activity, and occupational demands.
Physical Examination
- Inspection of knee alignment, checking for deformities or leg-length discrepancies.
- Palpation for tenderness, warmth, or swelling around the joint capsule.
- Assessment of range of motion, joint stiffness, and crepitus.
- Strength testing of surrounding muscles.
- Evaluation of joint stability, looking for signs of ligament laxity or joint instability.
This hands-on assessment helps distinguish knee osteoarthritis, inflammatory arthritis, and other joint problems, guiding the need for further diagnostic testing.
Diagnostic Tools Used for Knee Arthritis
To confirm a knee arthritis diagnosis and assess the degree of joint damage, orthopedic specialists may use the following diagnostic tools:
X-rays
- Identify joint space narrowing, bone spurs, and joint deformities.
- Detect poor alignment of the knee joint, contributing to wear and tear.
- Visualize bone density and signs of degeneration of the knee joint.
Magnetic Resonance Imaging (MRI)
- Provides detailed images of soft tissues, including cartilage, joint lining, and ligaments.
- Detects early degenerative changes not visible on X-rays.
- Assesses the entire joint, especially in younger patients or those with complex knee injuries.
Joint Aspiration and Blood Tests
- In cases of suspected inflammatory arthritis, fluid may be drawn from the joint to check for infection, crystals, or inflammation.
- Blood tests can help confirm autoimmune conditions like rheumatoid arthritis.
These tools assist in developing an accurate, stage-specific treatment plan and assessing the need for surgical interventions like knee replacement surgery or arthroscopic surgery.
Treatment Options for Different Stages of Arthritis
Management of knee arthritis depends on the stage of the disease, patient goals, and overall health.
Early to Moderate Arthritis Treatments
- Physical therapy to strengthen surrounding muscles, improve joint range of motion, and reduce stress on the knee joint.
- Anti-inflammatory medications and pain relievers to control arthritis pain with fewer gastrointestinal side effects.
- Joint injections, such as corticosteroids or hyaluronic acid, to reduce inflammation and provide short-term relief.
- Assistive devices, like braces or orthotics, to improve alignment and offload weight-bearing joints.
- Lifestyle changes, including weight loss, to reduce joint load and slow degeneration of the knee joint.
- Dietary supplements, such as glucosamine or chondroitin, though results vary by patient.
Advanced Arthritis Treatments
When nonsurgical treatments no longer control symptoms, surgery may be recommended:
- Arthroscopic surgery for debridement or repair of damaged cartilage in select patients.
- Knee osteotomy to realign the leg and shift weight off damaged parts of the joint (used in select younger patients).
- Total or partial knee replacement surgery to replace damaged parts of the knee with an artificial knee joint, reducing pain and restoring mobility.
Orthopedic specialists like Dr. Rytel carefully evaluate each patient’s condition, lifestyle, and risk factors to determine the most effective course of action.
Lifestyle Adjustments to Manage Arthritis Symptoms
Beyond medical treatment, lifestyle modifications play a vital role in managing arthritis in the knee:
- Maintain a healthy weight to reduce pressure on knee joints.
- Focus on low-impact exercises, such as swimming, cycling, and walking on even surfaces, to maintain fitness without overloading the knees.
- Implement specific exercises prescribed by a physical therapist to strengthen supportive muscles and improve joint stability.
- Use assistive devices as needed to reduce strain during daily activities.
- Apply cold or heat therapy to manage joint stiffness and flare-ups.
These adjustments can help reduce pain, preserve mobility, and delay the need for surgical interventions.
