Common Knee Conditions That We Treat

The knee, as one of the body’s primary load-bearing joints, is susceptible to a variety of complications and disorders. This can be resolved with the correct medical examination and care. Our clinic offers services for the following conditions:

Common Causes of Knee Pain

Knee pain may arise from a variety of conditions affecting any of the complex structures of the knee joint, including bones, cartilage, tendons, ligaments, and muscles.


  • Ligament Injuries: Tears in the knee’s ligaments often occur during activities that involve twisting or overextending the knee.
  • Meniscus Injuries: The meniscus can be torn during activities that put pressure on or rotate the knee joint, leading to pain and swelling.
  • Fractures: The patella or the bones forming the knee can fracture from falls or direct impacts. High-impact trauma is a common cause, especially in road traffic accidents or sports.
  • Tendon Tears: Sudden, sharp movements can result in tears of the quadriceps or patellar tendons, particularly in middle-aged individuals engaging in jumping sports.

Degenerative and Mechanical Issues

  • Osteoarthritis: Age-related wear and tear of the cartilage of the knee can lead to osteoarthritis, a common cause of knee pain in older adults.
  • Rheumatoid Arthritis: An autoimmune condition that can affect the knee, causing swelling and pain.
  • Patellofemoral Pain Syndrome: Also known as ‘runner’s knee’, this condition is characterised by pain arising from the contact between the patella and the femur.

Other Conditions

  • Bursitis: Inflammation of the bursae, which are small fluid-filled sacs around the knee, often due to repeated pressure on the knee or kneeling for long periods.
  • Gout: Caused by uric acid crystal accumulation in the joint, leading to intense pain and swelling.
  • Infections: Infections within the knee joint, such as septic arthritis, can cause severe pain and swelling.

Risk Factors

  • Overuse: Repeated stress on the knee, especially during high-impact sports, can lead to pain and inflammation over time.
  • Obesity: Excess body weight puts additional pressure on the knee joints, increasing the risk of degenerative changes and pain.
  • Muscle Weakness or Imbalance: Weakness or lack of flexibility in the muscles supporting the knee can lead to pain and injury.

Symptoms and Signs

Symptoms from knee conditions can range from mild to severe, affecting mobility and quality of life. These are some common symptoms that may indicate that you have a knee condition.

  • Pain – Pain in the knee can vary from mild discomfort to severe, sharp sensations. This symptom is common in various knee conditions such as osteoarthritis, ligament injuries (like ACL or MCL tears), and meniscal tears.
  • Swelling and Inflammation – Swelling and inflammation around the knee joint often indicate an acute injury or an inflammatory condition such as rheumatoid arthritis, bursitis, or gout.
  • Stiffness and Limited Range of Motion – Stiffness and a reduced ability to fully bend or straighten the knee are typical in degenerative conditions like osteoarthritis, and may also occur after prolonged periods of inactivity or injury.
  • Instability or Feeling of Giving Way – If the knee feels unstable or like it might buckle, this could be due to ligament damage (such as an ACL tear) or a sign of a weakening joint as seen in chronic conditions like osteoarthritis.
  • Clicking or Popping Sounds – Clicking or popping sounds during movement, without accompanying pain, might be harmless. However, if painful, it could indicate a meniscal tear or cartilage injury.
  • Difficulty Bearing Weight or Walking – Trouble with weight-bearing or walking can be a sign of a severe injury such as a fracture, a torn ligament, or severe arthritis.
  • Redness or Warmth in the Affected Area – Redness and warmth, especially when accompanied by swelling and pain, might indicate an infection or inflammatory conditions like rheumatoid arthritis or gout.
  • Deformity of the Knee Joint – Visible changes in the shape of the knee joint, such as bowing in or out, can occur in advanced stages of arthritis or after a significant injury like a fracture.
  • Tenderness Along the Joint Line – Pain upon touching along the sides of the knee could indicate a meniscal injury or collateral ligament damage.
  • Locking of the Knee – A knee that locks or gets stuck in a particular position might indicate a meniscal tear or loose bodies (small fragments of bone or cartilage) within the joint.


Clinical Assessment
  • Patient History: Gathering details about the pain and any related injury.
  • Physical Examination: Checking for signs of injury, movement range, and joint stability.
Imaging Studies
  • X-rays: Show bone changes and can indicate arthritis.
  • MRI: Offers a clear view of soft tissues, ligaments, and cartilage.
  • CT Scan: Provides detailed bone images and is used for complex cases.
  • Ultrasound: Used for real-time imaging of the knee during motion or procedures.
Laboratory Tests
  • Blood Tests: Detect signs of infection or inflammation.
  • Joint Fluid Analysis: Checks knee fluid for infection, gout, or inflammation.
Functional Assessment
  • Observation: Assessing walking and movement to understand the knee’s role in pain and mobility.

Non-Surgical Treatment Options


  • Analgesics: Pain relief through over-the-counter or prescription medications.
  • Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Reduce inflammation and alleviate pain.
  • Corticosteroids: Administered via injections to reduce severe inflammation.

Physical Therapy

  • Strengthening Exercises: Enhance muscle support around the knee.
  • Flexibility Workouts: Increase range of motion.
  • Modalities: Such as heat, ice, and ultrasound for pain management.

Lifestyle Modifications

  • Weight Management: Reducing body weight to lessen pressure on the knee.
  • Activity Alterations: Avoiding movements that exacerbate knee pain.

Assistive Devices

  • Braces: Provide support and stability to the knee joint.
  • Orthotics: Custom shoe inserts to improve alignment and distribute pressure.

Injection Therapies

  • Hyaluronic Acid: Supplements joint fluid to improve mobility and reduce pain.
  • Platelet-Rich Plasma (PRP): Uses a patient’s own blood components to promote healing.

Surgical Treatment Options

Surgical intervention may be considered when non-surgical treatments fail to relieve knee pain or when structural damage to the knee joint is significant.

  • Arthroscopy
    Arthroscopy is a minimally invasive technique that provides a detailed view of the interior of a joint, enabling diagnosis and treatment of joint issues. It may be suitable for patients with unresolved joint pain or suspected internal damage where non-invasive methods have failed.
  • Partial Knee Replacement
    This surgery involves replacing only the damaged section of the knee, preserving much of the natural joint.  Patients with localized knee damage may be suitable for this procedure.
  • Total Knee Replacement
    In total knee replacement, the entire knee joint is substituted with an artificial joint. This procedure may be recommended for severe arthritis or extensive joint damage where less invasive treatments are inadequate.
  • Osteotomy
    Osteotomy entails cutting and realigning the knee bones to redistribute stress and alleviate joint pressure. Younger patients with early-stage arthritis or knee deformities may consider this procedure to delay the need for total knee replacement.
  • Ligament Reconstruction
    This procedure, often involving ACL reconstruction, rebuilds torn ligaments to restore knee stability. Ligament reconstruction may be more suitable for physically active individuals or athletes who seek to regain full knee function.
  • Meniscus Repair
    Meniscus repair involves surgical correction or trimming of the torn meniscus to stabilize the knee and restore its functionality. This treatment may be recommended for patients with meniscal tears, particularly those wishing to avoid long-term joint degeneration.
  • Cartilage Repair
    Cartilage repair techniques, such as microfracture or autologous chondrocyte implantation, aim to repair or regenerate damaged knee cartilage.

Prevention Strategies

Knee pain can be prevented by integrating the following strategies into daily life:

  • Maintain Healthy Weight: Reduces stress on the knee joints, decreasing the risk of osteoarthritis and injuries.
  • Regular Exercise: Strengthens the muscles supporting the knee, improving joint stability.
  • Proper Technique and Equipment: Ensures activities such as sports or physical work do not strain the knees.
  • Flexibility Training: Enhances range of motion and prevents stiffness.
  • Adequate Nutrition: Supports joint health, with a focus on calcium and vitamin D for bone strength.
  • Ergonomic Workplace: Arrange physical spaces to avoid repetitive strain on the knees.
  • Avoiding High-Impact Activities: Reduces the risk of trauma and degenerative changes in the knee.
  • Wearing Appropriate Footwear: Cushions the knees and provides proper alignment during movement.
