Knee Pain Without Injury: What’s Going On?
Have you ever been wondering why does your knee hurt, even though you didn’t have any injuries in past or recently? The fact is your knee doesn’t need any traumatic event to have the pain. Non-traumatic pain can be caused by gradual soft tissue changes, Biomechanical stress on the joint or chronic joint or soft tissue conditions like, arthritis.
What Non-Traumatic Knee Pain Is
Non-traumatic knee pain refers to discomfort without a specific injury such as a fall, twist, or blow.
Common conditions include:
● Patellofemoral pain syndrome (PFPS)
● Knee osteoarthritis (OA)
● Tendinopathies and soft tissue dysfunction
● Activity-related pain patterns
These conditions are common in any age except kids. And they can get worse if not treated properly.
1. Patellofemoral Pain:
Patellofemoral Pain Syndrome (PFPS) is an umbrella term for pain arising from the patellofemoral/Knee joint or adjacent soft tissues. It is a chronic condition that worsens with activities such as squatting, sitting, climbing stairs, and running. The pain can be felt in all aspects of the knee, and symptoms can develop slowly over time or be brought on acutely
Common signs and symptoms:
● Gradual onset of pain, usually located around kneecap
● Worsens with joint loading activities like, stairs, running uphill
● Can be one sided or both sided
2. Knee Osteoarthritis: Non-Traumatic Degeneration
Knee osteoarthritis (OA), also known as degenerative joint disease, is typically the result of wear and tear and progressive loss of articular cartilage. It is most common in elderly people. Primary OA is articular degeneration without any underlying cause, whether secondary OA can be caused by post-traumatic or abnormal articular cartilage changes.
Common signs and symptoms:
● Intermittent or constant knee pain
● Worsens with activities
● Morning stiffness for less than 30 mins and swelling
● Pain after prolonged sitting, resting
● Cracking sound with joint movements
● Knee locking or giving away
● Difficulty walking, using stairs, performing household chores
3. Patellar tendinopathy:
Patellar tendinopathy, commonly referred to as jumper’s knee, is a frequent cause of anterior knee pain in athletes exposed to repetitive high-load jumping and running activities. The condition is most common in men, with a higher incidence among adolescents and young adult
Common signs and symptoms:
Localized pain in inferior pole of the patella (bottom part of the kneecap)
Pain with prolonged sitting, squatting, stair climbing
Pain relief shortly after load is removed/non-weight bearing positions
Physiotherapy Treatment
The evidence supports physiotherapy as a core non-operative intervention for non-traumatic knee pain:
Manual Therapy:
● Specific joint mobilizations improve the joint mobility and reduce discomfort with movements
Exercise Therapy
● Strengthening (quads, hip abductors/externals) and movement retraining are central to PFPS and OA management.
Biomechanical Interventions
● Footwear modifications and insoles may reduce joint loads during gait
Other modalities
● Treatments like shockwave therapy, Dr needling and Acupuncture have emerging evidence, especially for tendinopathies and chronic pain.
OA-Specific Strategies
● Physiotherapy for OA emphasizes exercise, education, and self-management as the cornerstone of care.
If you’re experiencing persistent knee pain, don’t wait for it to “just go away.” Early assessment and targeted rehabilitation can significantly shorten recovery time and prevent the condition from becoming chronic.
