Articular cartilage
Cartilage covers the ends of the bones and helps the knee move smoothly. Explore arthritis and cartilage treatment.
How are cartilage and the meniscus different? →Does the X-ray grade always match the pain? →Do hyaluronic acid injections regenerate cartilage? →Meniscus
The menisci distribute force between the thighbone and shinbone. Treatment depends on the type of tear.
Does a degenerative meniscal tear require surgery first? →Why are meniscal root tears discussed separately? →Why is rehabilitation different after meniscal repair? →Anterior cruciate ligament
The ACL supports stability inside the joint. After injury, we assess instability and your activity goals together.
When is ACL reconstruction considered, and when is rehabilitation appropriate? →What does an ACL tear on an MRI report mean? →Return to sport after ACL surgery is not a calendar decision →Posterior cruciate ligament
The PCL limits backward movement of the shinbone. Learn how posterior and side ligament injuries differ.
Posterior and Side Ligaments: Different Injuries, Different Roles →What tissues are inside the knee? →Collateral ligaments
The collateral ligaments support the sides of the knee. We assess which side is injured and whether other tissues are involved.
Posterior and Side Ligaments: Different Injuries, Different Roles →Is pain on the inside of my knee osteoarthritis? →Kneecap and tendons
The kneecap and tendons at the front of the knee help transmit muscle force. Explore pain on stairs and when standing from a chair.
Anterior knee pain: assess the kneecap and muscles together →Why is going downstairs harder on my knee? →What happens to the kneecap during replacement? →Bones and alignment
Leg alignment relates to the path of forces through the knee. Explore X-rays and osteotomy.
Bone healing and weight bearing after osteotomy →Does the X-ray grade always match the pain? →What does a total knee replacement replace? →Synovium and joint fluid
The synovial lining and joint fluid help explain knee swelling and effusions.
What does fluid in the knee mean? →A lump behind my knee: could it be a Baker’s cyst? →What can a steroid injection achieve? →Iliotibial band
A band of tissue runs down the outer thigh. Explore outer knee pain during running and how to manage training load.
Outer Knee Pain: Is the Iliotibial Band Involved? →Returning after injury: use function and the next-day response →Exercise, medicines, surgery and recovery
Start with your question
What does fluid in the knee mean?
Identify why fluid has increased before deciding whether it should be removed.
Do all painful knees need an MRI?
First ask which treatment decision the test could change.
If I have arthritis, can I exercise?
Learn how to start strengthening, walking and cycling, and adjust the amount to your symptoms.
What should I check when knee pain disrupts sleep?
Include the pattern of night pain and its effect on sleep in treatment decisions.
Why is going downstairs harder on my knee?
Consider controlled lowering, strength and safe movement together.
What materials are used in a knee replacement?
Understand the roles of metal, polyethylene and bone cement, and what matters when discussing implant materials.
How long can a knee implant last?
Duration depends on the implant, fixation and the individual course.
How should partial and total knee replacement be compared?
The extent of arthritis and ligament function matter before incision size.
Exercise and daily preparation before knee replacement
Maintain feasible movement and prepare for recovery rather than training through pain.
When can I drive or travel after knee replacement?
Being able to sit in a car is different from being able to brake in an emergency.
