<p>A device for measuring the lateral position of the patella relative to the femur of an individual comprising a patella calliper with a first pair of jaws comprising a first jaw with a first jaw face and a second jaw with a second jaw face, said first and second jaws being capable of movement towards and away from each other, to allow said jaw faces to contact, in use, the outer edges of a patella a femur calliper with a second pair of jaws, comprising a first jaw with a first jaw face and a second jaw with a second jaw face, said first and second jaws being capable of movement towards and away from each other, to allow said jaw faces to contact, in use, the outer edges of a femur, adjacent the patella, the first pair of jaws being movably attached to the second pair of jaws and measuring means to measure the lateral displacement of the first pair of jaws relative to the second pair of jaws. The device is best illustrated by figure 1 of the drawings. Also, a kit comprising the device and a further calibration device comprising two forms, one of a greater diameter than the other, collocated in such a way that the forms share a common axis.</p> |
