Common causes
- Osteoarthritis, the slow wear and repair of the joint, often in both knees
- Pain at the front of the knee (patellofemoral pain), common in younger and active people
- Meniscus or ligament injury, often after a twist
- Tendon pain below or above the kneecap
- Weak thigh and hip muscles, which put more load on the knee
- Less common causes such as inflammatory arthritis, gout or infection, which the doctor checks for

When to get help urgently
Common questions
Is walking bad for knee osteoarthritis?
No. Walking and strengthening exercise are among the most helpful treatments. Start with short walks and build up. Pain that settles within a day is usually safe.
Can knee osteoarthritis be reversed?
The changes in the joint do not reverse, but pain and function often improve a lot with exercise, weight loss and good pain control.
Do knee injections help?
Steroid injections can ease a flare for some weeks. Other injections, such as hyaluronic acid or PRP, have mixed evidence. The doctor will explain the options and whether any are suitable for you.
Will I need a knee replacement?
Many people do not. If pain and function stay poor despite good treatment, the doctor will discuss a referral to an orthopaedic surgeon.
Does losing weight help my knees?
Yes. Even a small weight loss reduces the load on the knee and often reduces pain.
