42
What is genu valgum?
when the knees move inwards (medially)
43
What is genu varum?
when the knees move outwards (laterally)
44
What is Osgood Schlatter's?
traction periostitis of the tibial tuberosity
45
What is the mechanism of Osgood Schlatter's?
overuse/repetitive stress
46
What is the management for Osgood Schlatter's?
- RICE - NSAIDs - progressive rehabilitation
47
What is the presentation of Osgood Schlatter's?
- local pain at the tendon attachment to the tibia (during and after exercise) - tenderness and swelling at the point of attachment - xray may show bone fragmentation at the tibial tuberosity
48
What are the complications of Osgood Schlatter's?
- reinjury - possible avulsion fracture
49
What is a patellar tendon rupture?
rupture or partial rupture to the patella tendon (often at the point of attachment to the patella) - may be called jumpers knee
50
What is the mechanism of a patellar tendon rupture?
repetitive and high amount of jumping and lunging activities (classed as high impact)
51
What is the management for a patellar tendon rupture?
- RICE - NSAIDs - progressive rehabilitation - possible imbolisation
52
What is the presentation of a patellar tendon rupture?
- pain and tenderness over the patella tendon at point of attachment (distal aspect of patella) - aching and stiffness after exertion
53
What is the complications of a patellar tendon rupture?
- reinjury - reduced performance
54
What is the Q (quadricep) angle?
angle between the line of quadriceps (ASIS to midpoint of patella) and the line of the patella tendon to the tibial tuberosity
