5 Signs Your Knee Pain Is More Than Just Wear and Tear
Written by Mamdouh Sarhan, MSc, MCSP, HCPC Reg.'It's just wear and tear' is one of the most common — and most unhelpful — things people are told about their knee pain. While osteoarthritis does involve structural changes in the knee joint, the relationship between those changes and pain is far more complex than most people realise. Many patients with significant structural changes on their X-ray have little or no pain, while others with minimal structural changes have severe symptoms. Here are five signs that your knee pain is more than just wear and tear — and that physiotherapy can make a real difference.
Sign 1: Your Pain Is Worse After Sitting for Long Periods
Pain that is worse after prolonged sitting and improves with movement is a classic sign of patellofemoral pain syndrome (PFPS) — sometimes called 'runner's knee' or 'cinema sign.' This is a highly treatable condition that responds very well to physiotherapy. It is caused by poor tracking of the kneecap in its groove, often due to weakness in the hip and quadriceps muscles. This is not 'wear and tear' — it is a biomechanical problem with a clear solution.
Sign 2: Your Knee Locks, Catches, or Gives Way
Locking, catching, or giving way of the knee suggests a mechanical problem within the joint — most commonly a meniscus tear or a loose body. These symptoms are not typical of straightforward osteoarthritis and warrant a proper assessment. A physiotherapist can assess the likelihood of a meniscal injury and advise whether imaging or an orthopaedic referral is appropriate. Many meniscal tears respond well to physiotherapy without surgery.
Sign 3: Your Knee Is Swollen
Persistent swelling in the knee — particularly if it came on after a specific incident — suggests an inflammatory process or structural injury. This could be a ligament sprain, a meniscal tear, or an inflammatory arthritis flare. Swelling is the knee's response to injury or irritation, and it is not something to ignore. A physiotherapy assessment can determine the likely cause and guide appropriate management.
Sign 4: Your Pain Is Only on One Side of the Knee
Pain that is localised to one specific area of the knee — the inner side, the outer side, or directly below the kneecap — is more likely to have a specific structural cause than generalised 'wear and tear.' Inner knee pain may indicate medial collateral ligament involvement or pes anserine bursitis. Outer knee pain may suggest iliotibial band syndrome or lateral meniscal pathology. Pain below the kneecap in younger patients may indicate patellar tendinopathy. Each of these conditions has a specific treatment approach.
Sign 5: Your Pain Has Changed or Worsened Recently
If you have had knee pain for some time that was previously stable, and it has recently changed in character, location, or severity, this warrants reassessment. A change in symptoms may indicate a new injury superimposed on existing arthritis, a change in your activity level or biomechanics, or a different pathology altogether. Do not assume that worsening knee pain is simply 'more wear and tear' — get it properly assessed.
What Can Physiotherapy Do for Knee Pain?
Physiotherapy is the most evidence-based treatment for knee pain — including knee osteoarthritis. A structured physiotherapy programme that includes targeted strengthening of the quadriceps, hamstrings, and hip muscles, combined with manual therapy and activity modification, has been shown to reduce pain and improve function as effectively as surgery in many cases. The key is a proper assessment to identify the specific factors driving your pain, followed by a targeted treatment plan — not generic exercises from the internet.
