Physiotherapists in Oxford treat many different conditions including the issues profiled below.

Meniscal Tears

Each knee has a pair of interesting structures inside it known as the menisci, more commonly called the knee cartilages. They are cartilaginous structures a bit like banked tracks and attached to the top of the tibia on each side of the knee. Their upper curves surfaces accommodate the large curved condyles of the end of the femur which otherwise would have to articulate solely with the flat upper tibial surface. The function of the menisci is not entirely clear but they may have to do with distributing synovial fluid around the joint, giving the brain feedback on where exactly the knee is during activities or easing force transmission across the joint as it fills in the gaps between the two joint surfaces.

During movements of the knee the large femoral condyles can pinch the menisci against the tibial surfaces and cause tears in the substance of the meniscus. A small tear from the outside of the structure can cause a flap which is called a .parrot beak. tear. If the tear is horizontal along the plane of the meniscus and does not reach the edge then a flap can be produced which is known as a .bucket handle. tear.

The Sacro-Iliac Joint

The sacro-iliac joints are a pair of large irregular joints at the base of the spine which connect the sacrum, the triangular bone below the lumbar vertebrae, with the ilium, the large wings of the pelvis. It is a synovial joint like the fingers or knees but has very limited movement and functions to transfer the weight of the upper body from the spine to the hips. The sacro-iliac joint has very strong ligaments which travel the very short distances between the two highly irregular joint surfaces. There are no muscles which can act to produce real movements of the joint as other joints move and it functions as the weight transmitting and stress relieving pelvic joint.

The sacro-iliac joints are designed to absorb the torsional stresses which occur in the pelvis during gait and do have small degree of movement to help them manage this function. The irregular joint surfaces with its depressions and prominences allow the sacrum to lock between the iliac bones so that it cannot be driven downwards by the weight of the body. The irregular joint surfaces also prevent the sacrum being rotated inappropriately, with its strong ligaments being responsible for absorbing pelvis stresses during walking.
