Most knee pain, including osteoarthritis and aches around the kneecap, gets better with targeted strengthening, sensible changes to activity and clear advice. Surgery is needed far less often than many people expect.
At Tylurs com, our physiotherapists start by working out what is driving your symptoms, whether that is osteoarthritis, irritation around the kneecap, an injured ligament or an overloaded tendon. You then get a plain explanation and a plan you can follow between sessions.
Key takeaways
- Most knee pain improves with strengthening and activity changes; surgery is needed far less often than people expect.
- Exercise is a core treatment for knee osteoarthritis and does not wear the joint out faster.
- Strong thigh and hip muscles take load off the joint and help control the kneecap.
- A hot, red, swollen knee with fever, or being unable to bear weight after an injury, needs urgent medical help.
Common symptoms of knee pain
Knee problems show up in different ways. These are the symptoms people most often describe:
- Ache around or behind the kneecap
- Stiffness after rest or first thing in the morning
- Swelling or puffiness around the joint
- Pain on stairs, squatting or kneeling
- Clicking, catching or locking
- Knee giving way or feeling unstable
What causes knee pain?
The knee takes a large share of your body weight every time you walk, climb stairs or squat, so it is prone to both sudden injuries and gradual overload. These are the causes we see most often.
Knee osteoarthritis
Osteoarthritis is the most common type of arthritis in the UK, and the knee is one of the joints it affects most. The cartilage lining the joint thins and the joint works harder to repair itself, causing pain, stiffness and sometimes swelling. It is not simply “wear and tear”: many people with X-ray changes have little pain, and symptoms often go up and down rather than steadily worsening.
Pain around the kneecap
Often called runner’s knee, patellofemoral pain is an ache around or behind the kneecap. It tends to flare on stairs, when squatting or kneeling, running downhill or after sitting for a long time. Our article on runner’s knee physiotherapy covers the training changes that help.
Ligament, meniscus and tendon problems
A twist or sudden change of direction can sprain the anterior cruciate ligament (ACL) or tear a meniscus. Clues include a pop, swelling within hours, giving way, or catching and locking. Pain just below or above the kneecap with jumping or running is more likely an overloaded tendon; our guide to tendinopathy explains why these respond to gradual loading rather than rest.
Pain from nearby joints
Not every case starts in the knee. A problem in the hip can refer pain down the thigh, and weak hip muscles change how load passes through the joint. If you also have groin or outer-hip symptoms, read our guide to hip pain.
What your symptoms can suggest
Where your knee hurts and what makes it worse give useful clues, although only a proper assessment can confirm the cause.
| What you notice | Possible cause |
|---|---|
| Ache around the kneecap, worse on stairs, squatting or long sitting | Patellofemoral pain |
| Stiffness after rest, pain on longer walks, gradual onset in middle age | Knee osteoarthritis |
| Pain just below or above the kneecap with jumping or running | Patellar or quadriceps tendinopathy |
| Twisting injury, rapid swelling, knee giving way | Ligament injury, such as the ACL |
| Pain on the joint line with catching or locking | Meniscus tear |
How we assess knee pain
We ask how the pain began, what eases and aggravates it, and what you want to get back to. We then watch you walk, squat, step down and balance on one leg, test thigh and hip strength, and gently examine the ligaments, menisci and kneecap.
For most people with suspected osteoarthritis, a scan is not needed. NICE guidance advises that it can be diagnosed clinically in people aged 45 or over with activity-related joint pain and no morning stiffness, or stiffness lasting no longer than 30 minutes.
Physiotherapy treatment for knee pain
Exercise is the foundation of treatment for most knee problems. For osteoarthritis, NICE describes therapeutic exercise and weight management (where appropriate), with information and support, as the core treatments. At the Tylurs com physiotherapy clinic, your programme is tailored to your knee, fitness and goals.
Strengthening the thighs and hips
Strong thigh muscles act as shock absorbers and help control the kneecap. We usually begin with sit-to-stands from a raised chair, straight-leg raises, step-ups and supported mini-squats, then progress them as the knee settles. Bridges, side-lying leg lifts and banded side steps build the hip muscles that stop the knee drifting inwards.
Adjusting activity without stopping
Complete rest rarely helps in the long run, because muscles weaken and the joint becomes less tolerant of load. Instead, we find the level your knee can handle now and build from there:
- shorten runs or walks, or split them into two
- swap some sessions for cycling or swimming
- add hills, stairs and deeper squats back gradually
- spread kneeling jobs, such as gardening, across the week
A little discomfort during exercise is usually acceptable, as long as it settles within about 24 hours and is not building from week to week.
Weight, supports and hands-on care
If you are carrying extra weight, losing some reduces the load through your knees with every step; NICE notes that any amount of weight loss is likely to help people with osteoarthritis. Taping, braces and insoles are short-term aids that we suggest only when they keep your programme moving. Manual therapy can ease stiffness and make exercise more comfortable.
When to seek urgent medical help
Most knee problems are not an emergency, but the NHS treats these as warning signs that need a doctor before physiotherapy:
- a hot, red, swollen knee with a high temperature or shivers, which can signal a joint infection
- being unable to put weight on the leg after an injury, or a knee that has changed shape
- a knee that locks, will not straighten or keeps giving way
- pain, swelling and warmth in the calf, especially after surgery or long travel, which can signal a blood clot
Get help with knee pain
You do not have to put up with a knee that limits your walks, sport or sleep. The Tylurs com team combines a thorough assessment with a progressive exercise plan and practical advice. If your problem started on the pitch, our sports injury rehabilitation service takes you from the first sore days back to training, and you can browse more conditions we treat.
Book your knee assessment and leave with a clear plan for your next steps.
Knee pain: frequently asked questions
Is it safe to exercise with knee osteoarthritis?
Yes. NICE lists therapeutic exercise as a core treatment for osteoarthritis, and it does not wear the joint out faster. Your knee may ache a little more at first, which is normal. Aim for activity where any extra discomfort settles by the next day, and build up gradually.
Should I wear a knee brace or support?
A brace can help for a short time, for example to give confidence after a ligament injury, but it is rarely a long-term fix. Relying on a support can let the muscles weaken. We suggest braces, sleeves or tape only when they help you stay active, with a plan to wean off them.
Why does my knee hurt more going down stairs than up?
Going downstairs asks your thigh muscles to control your body weight as they lengthen, and presses the kneecap firmly against the thigh bone. That is why kneecap pain and early osteoarthritis often show on the way down. Strengthening the quadriceps and hips usually helps, and using the handrail eases things meanwhile.
Will I end up needing a knee replacement?
Most people with knee osteoarthritis manage without surgery. Symptoms often stay stable or improve with regular exercise, weight management where relevant and good pain control. A replacement is usually considered only when pain and stiffness seriously affect your life despite non-surgical care, and being stronger beforehand makes rehabilitation smoother.
