Knee pain is one of the most common reasons patients seek advice from an orthopaedic surgeon.
It can develop gradually through wear and tear, or appear suddenly following an injury or twist. Understanding the underlying cause is the first step toward effective treatment, and toward getting back to the activities you enjoy without pain.

ToggleBelow, Mr David Stitson, Consultant Orthopaedic Surgeon at The Nuffield Hospital in Plymouth, explains six of the most common conditions that can lead to knee damage, what causes them, and the symptoms to look out for.
If the knee is locking, there is instability, accompanied by significant pain and reduced mobility, a total knee replacement may be recommended if conservative measures haven’t helped.
Six of the most common conditions that can lead to knee damage
1. Osteoarthritis
Osteoarthritis is the most common cause of long-term knee pain. Over time, the cartilage that cushions the joint gradually wears away, leaving bone to rub against bone. This causes pain, stiffness and swelling that typically worsen with activity and age, particularly from the mid-40s onwards.
2. Rheumatoid Arthritis
Unlike osteoarthritis, rheumatoid arthritis is an autoimmune condition. The immune system mistakenly attacks the lining of the joint, causing chronic inflammation, swelling and, over time, damage to both cartilage and bone. It can affect people of any age and often involves several joints at once.
3. Meniscus Tears
Each knee has two C-shaped discs of cartilage, called menisci, which cushion and stabilise the joint. These can tear suddenly during a twisting movement or a sports injury, or gradually as part of normal wear and tear. A meniscus tear often causes pain, swelling, locking or a catching sensation when moving the knee.
4. Anterior Cruciate Ligament (ACL) Tears
The ACL is one of the key ligaments that keeps the knee stable. A sudden twist, pivot or direct impact, (common in sports such as football, rugby and skiing) can tear it. This usually causes immediate swelling and a feeling of instability, and increases the risk of early arthritis if left untreated.
5. Patellofemoral Pain Syndrome
Often called ‘runner’s knee’, this condition develops when the kneecap does not track smoothly over the thighbone, usually due to repetitive stress or muscle imbalance. It typically causes an ache around or behind the kneecap that becomes more noticeable with running, squatting or climbing stairs.
6. Bursitis
Small fluid-filled sacs called bursae cushion the knee joint and reduce friction between moving parts. Repeated kneeling, overuse or minor trauma can cause these to become inflamed, leading to localised swelling, warmth and tenderness, a condition known as bursitis.
When Should You See a Knee Specialist?
Occasional knee stiffness after exercise is common and often nothing to worry about. However, you should consider seeing an orthopaedic specialist if you experience:
- Knee pain that persists for more than a few weeks or keeps returning
- Swelling, warmth or redness around the joint
- A feeling of instability, or the knee giving way
- Locking, catching or an inability to fully straighten the knee
- Pain that disturbs your sleep or limits everyday activities
Early diagnosis often means simpler, less invasive treatment. In many cases, physiotherapy, activity modification or targeted injections can resolve symptoms without the need for surgery, but the right diagnosis is essential to choosing the right treatment.
Solutions: What Can Be Done About a Damaged Knee?
Physiotherapy is often the first step, particularly for instability related to muscle weakness or patellar tracking issues. A tailored strengthening and proprioception programme can significantly improve symptoms.
Activity modification and bracing can help manage symptoms while a longer-term plan is developed, particularly for milder cartilage issues or early arthritis.
Arthroscopic (keyhole) surgery is commonly used to trim or repair a torn meniscus, remove loose bodies or address certain cartilage damage. Recovery from a knee arthroscopy is generally quicker than open surgery, with many patients returning to light activity within a few weeks.
Ligament reconstruction, such as ACL reconstruction, may be recommended if instability is significant, particularly for those wanting to return to sport or physically demanding work.
Realignment procedures can address recurrent patellar instability by correcting how the kneecap tracks.
Knee joint replacement may be considered for advanced osteoarthritis. If the knee is locking, there is instability, accompanied by significant pain and reduced mobility, a total knee replacement may be recommended if conservative measures haven’t helped. A partial knee replacement is an alternative to total knee replacement for some people with osteoarthritis and is limited to a single compartment of the knee.

About Knee Surgery
Knee replacement surgery replaces the worn out, painful and stiff knee joint with a new prosthetic joint. This procedure which may be a partial or a total replacement is normally performed under spinal anaesthesia and is usually followed by a night or two in the hospital.
