Knee Arthritis

 

Knee Osteoarthritis Treatment in Princeton & Lawrenceville, NJ

Knee osteoarthritis is a common cause of knee pain, stiffness, and swelling. It develops gradually as cartilage within the joint wears down over time.

Many people assume arthritis means they must stop being active. That is not true. With the right plan, most individuals can stay mobile, strong, and engaged in the activities they enjoy.

At Princeton Sports and Family Medicine, P.C., we focus on reducing pain, improving function, and helping patients in Princeton, Lawrenceville, West Windsor, Plainsboro, Hopewell, Pennington, and Robbinsville maintain long-term joint health.

Who This Affects + Why It Happens

Knee osteoarthritis affects:

• Adults over 40
• Former athletes
• Active adults with prior knee injuries
• Individuals with higher body weight
• People with long-standing alignment differences

Why It Happens

Osteoarthritis is a degenerative joint condition. Over time:

• Cartilage thins
• Joint space narrows
• Bone spurs may form
• Inflammation increases

Previous ACL injury, meniscus tear, or cartilage injury increases risk.

Risk Factors

• Age
• Prior knee injury
• Obesity
• Repetitive high-impact loading
• Poor lower-extremity strength
• Genetic predisposition

Symptoms: What’s Normal vs. Not

Typical Knee Osteoarthritis Symptoms

• Gradual onset knee pain
• Morning stiffness lasting less than 30–60 minutes
• Pain with prolonged walking
• Swelling after activity
• Decreased range of motion
• Grinding sensation

Seek Urgent Care Now If:

• Sudden severe swelling
• Inability to bear weight
• Fever with joint swelling
• Significant redness and warmth
• Sudden locking

These may indicate infection, fracture, or other urgent conditions.

Diagnosis

Diagnosis combines history, exam, and imaging when appropriate.

What We Assess

• Pain pattern
• Activity limitations
• Range of motion
• Strength
• Alignment
• Functional movements

Imaging

• X-rays are commonly used to evaluate joint space narrowing and arthritis changes.
• MRI is usually not necessary unless another condition is suspected.

Importantly, imaging severity does not always match pain severity.

What to Expect at Your Visit

• Clear explanation of arthritis stage
• Discussion of contributing factors
• Activity and exercise guidance
• Long-term management plan

Treatment Options

Knee osteoarthritis treatment focuses on improving function and reducing pain.

Self-Care Basics

• Stay active
• Avoid prolonged inactivity
• Ice after flares
• Heat before activity for stiffness
• Supportive footwear

Rehab / Physical Therapy Focus

• Quadriceps strengthening
• Hip strengthening
• Glute activation
• Balance training
• Gait retraining
• Controlled impact progression

Strength is one of the most powerful treatments for arthritis.

Weight Management

Even modest weight reduction reduces joint load and pain.

Medications

• Acetaminophen may help mild pain
• Short-term NSAIDs may reduce inflammation
• Discuss risks of long-term NSAID use
• Topical NSAIDs may be appropriate

Injections

In certain cases, injections may be discussed for symptom management. These decisions are individualized.

Surgery

Surgical referral may be considered when:

• Severe pain limits daily life
• Non-operative care fails
• Significant joint degeneration is present

Many patients manage arthritis effectively without surgery for years.

Return to Activity Guidance

Movement is medicine.

Early Phase

• Low-impact cardio (cycling, swimming)
• Gentle mobility

Mid Phase

• Progressive strength training
• Controlled step work
• Light incline walking

Late Phase

• Return to recreational sports as tolerated
• Impact activities introduced carefully
• Ongoing maintenance strength

Common Mistakes to Avoid

• Avoiding all activity
• Relying only on medication
• Skipping strength training
• Training through severe swelling
• Ignoring footwear
• Assuming pain equals damage

Prevention / Slowing Progression

• Maintain healthy weight
• Strength train consistently
• Stay active
• Avoid rapid spikes in impact
• Address knee injuries early
• Improve hip strength
• Wear supportive shoes
