Presentation 1:
Osteoarthritis Knee
Definition:
Osteoarthritis (OA) is a condition in
which the cartilage between the joints
is wears away leading to pain and
stiffness.

Anatomy of the knee
Source: WebMD
The knee joins of femur to the tibia, fibula and also patella.
Tendons that stabilize the knee are:
(a)Anterior Cruciate Ligament: prevent femur from sliding backward on the tibia (or tibia sliding backward on the femur).
(b)Posterior cruciate ligament: prevents the demur from sliding forward on the tibia (or the tibia sliding backward on the femur).
(c)Medial and Lateral collateral ligaments: prevent from sliding side to side.
Two C-shaped of cartilage that called medial and lateral menisci that act as absorber.

SIGN
Reduced range of joint movement.
Pain on movement of the joint or at
extremes of joint movement.
Joint swelling/ synovitis (warmth,
effusion, synovial thickening).
Periarticular tenderness.
Crepitus.
