Top 10 Causes of Knee Pain and How to Treat Them

Knee pain affects millions globally, limiting mobility and daily activities. Understanding the causes and treatments prevents chronic damage and accelerates recovery. Dr. Mufaddal Gombera, MD, an Orthopedic Surgeon at Mufaddal Gombera, MD / Fondren Orthopedic Group, emphasizes:

"Early diagnosis and individualized treatment plans are crucial to restoring knee function and preventing long-term joint deterioration."

Dr. Gombera is a Board-Certified Orthopedic Surgeon and Sports Medicine specialist. He completed Medical School at Baylor College of Medicine, Orthopedic Surgery residency at University of Michigan, Ann Arbor, and a Sports Medicine & Shoulder Fellowship at Northwestern University, Chicago. He has served as Assistant Team Physician for Northwestern Football, Chicago Cubs, and Chicago Blackhawks, and currently is Director of the Hip Preservation Center at Texas Orthopedic Hospital and Clinical Assistant Professor at UTMB. He is an active member of the American Academy of Orthopedic Surgeons (AAOS), Arthroscopy Association of North America, and American Orthopedic Society for Sports Medicine.

1. Osteoarthritis: Why Does Your Knee Degenerate?

Osteoarthritis (OA) occurs when cartilage wears down, causing bone friction. Common in adults over 50, OA triggers swelling, stiffness, and pain.

Treatment:

  • Physical therapy strengthens supporting muscles.
  • NSAIDs reduce inflammation.
  • Corticosteroid injections relieve flare-ups.
  • Joint replacement for advanced degeneration.

Example: 60% of adults with knee OA experience daily activity limitations.

2. Meniscus Tears: How Do You Know If You’re Injured?

Meniscus tears result from twisting or sudden impacts. Symptoms include swelling, locking, or clicking.

Treatment:

  • RICE for mild tears.
  • Physical therapy restores range of motion and stability.
  • Arthroscopic surgery repairs or removes damaged tissue.

Note: Athletes have higher risk due to pivoting movements.

3. Ligament Injuries: Which Ligament Causes the Most Pain?

ACL (anterior cruciate ligament) and MCL (medial collateral ligament) injuries are common in sports. ACL tears cause instability; MCL tears cause localized pain.

Treatment:

  • Bracing and activity modification for partial tears.
  • Surgery reconstructs ACL in high-demand athletes.
  • Rehabilitation strengthens muscles and improves balance.

Statistic: ACL injuries affect approximately 200,000 people annually in the U.S.

4. Tendinitis: Can Overuse Lead to Chronic Knee Pain?

Patellar tendinitis, or “jumper’s knee,” occurs from repetitive stress. Pain appears below the kneecap, especially in athletes.

Treatment:

  • Ice and anti-inflammatory medications reduce discomfort.
  • Eccentric strengthening exercises improve tendon resilience.
  • PRP injections for persistent cases.

Example: Basketball and volleyball players show 20–30% prevalence.

5. Bursitis: What Causes Swelling in the Knee?

Bursitis inflames fluid-filled sacs (bursae) cushioning joints. Causes include repeated kneeling or trauma.

Treatment:

  • Rest and ice reduce inflammation.
  • NSAIDs control pain.
  • Aspiration or corticosteroid injections for severe swelling.

Observation: Prepatellar bursitis is common among construction workers and carpet layers.

6. Gout: Can Diet Trigger Sudden Knee Pain?

Gout forms uric acid crystals in the knee, causing intense pain, redness, and swelling.

Treatment:

  • NSAIDs or colchicine reduce acute flare-ups.
  • Lifestyle adjustments limit purine-rich foods.
  • Long-term medications lower uric acid levels.

Statistic: 25% of gout cases involve the knee joint.

7. Rheumatoid Arthritis: How Does Autoimmunity Affect Knees?

Rheumatoid arthritis (RA) is an autoimmune disorder attacking joint linings, causing symmetrical pain, swelling, and morning stiffness.

Treatment:

  • DMARDs slow disease progression.
  • Physical therapy maintains joint function.
  • Biologic therapies target specific immune pathways.

Fact: Early intervention reduces irreversible joint damage by up to 50%.

8. Iliotibial Band Syndrome: Why Does the Outer Knee Hurt?

IT band syndrome occurs in runners or cyclists, causing lateral knee pain. Friction between the IT band and femur triggers inflammation.

Treatment:

  • Stretching and foam rolling relieve tension.
  • Strengthening hip abductors improves alignment.
  • Activity modification reduces repetitive stress.

Data: Up to 12% of runners report IT band syndrome annually.

9. Patellofemoral Pain Syndrome: What Makes Kneecaps Ache?

This syndrome causes anterior knee pain due to cartilage misalignment or overuse. Symptoms worsen with stairs or prolonged sitting.

Treatment:

  • Quadriceps strengthening improves tracking.
  • Orthotics correct biomechanical misalignments.
  • Activity modification prevents aggravation.

Example: Adolescent athletes show higher incidence due to growth-related changes.

10. Knee Fractures: When Is Surgery Necessary?

Knee fractures involve the patella, tibial plateau, or femur. High-impact trauma or falls are common causes.

Treatment:

  • Immobilization stabilizes minor fractures.
  • Surgery fixes displaced fractures.
  • Rehabilitation restores mobility and strength.

Statistic: Tibial plateau fractures occur in 10–20 per 100,000 people annually.

How to Protect Your Knees

Preventive measures reduce knee pain risk:

  • Maintain healthy weight to reduce joint load.
  • Strengthen quadriceps, hamstrings, and hip muscles.
  • Use proper techniques in sports and daily activities.
  • Incorporate low-impact exercises like swimming or cycling.

Dr. Mufaddal Gombera, MD, advises: “Customized exercise programs and early imaging can prevent minor injuries from becoming chronic knee problems.”
