The anterior cruciate ligament (ACL) is one of the two strong cords that stabilise the interior of the knee. The ACL stops the tibia moving forwards on the femur and also preventing some twisting movements of the knee. Injury classically happens when the knee is twisted suddenly when changing direction.
Symptoms and Signs People will classically mention that the foot was fixed on the floor / landed awkwardly and then felt a pop or snap in the knee. This is often accompanied with large rapid swelling to the knee and an inability to continue the activity they are playing. Given time the swelling and pain […]
There are two menisci in the knee. One on the inside (medial side – where your knees touch one another) and one on the outer side (lateral side). In younger patients the menisci can tear due to a twisting injury during sporting activity and in older people may be a degenerate tear sustained from something […]
The ends of the bones are coated in a smooth, white lining called cartilage. This structure is highly specialised and creates an almost frictionless surface for the knee surfaces to glide against. Any injury to this smooth gliding surface alters these properties and will cause symptoms within the knee. Injuries to the cartilage can be […]
The patella is held in place by ligaments and muscles when your knee is fully straight. When the knee bends, the stability increasingly comes from the interplay between the shape of the bones, namely the patella and the deepened groove at the end of the thigh bone (trochlea). In simple visual terms the bottom of […]
Knee ‘osteoarthritis’ is a term for ‘wear and tear’ in the knee. This osteoarthritis is caused when the lining of the knee (articular cartilage) becomes thinner, fragments and wears away. You will be at a higher risk of developing arthritis if you have had a previous injury to your knee, particularly if you have injured […]
I have injured my knee, what next? We have recently done undertaken research that is ongoing in this area and are currently trying to promote the diagnosis of knee injuries amongst health care colleagues. A frustrating, recurring theme is the multitude of knee injuries that do seek out help initially only to be told that […]
