ABSTRACT:
A knee joint laxity measuring and displaying apparatus includes a housing 1 and a strap holder 2 interfixed by rods 3 and connectible to the lower leg by straps 15 and 16. A clinometer 11 mounted in the housing 1 measures internal-external rotation of the tibia with reference to the vertical. Electrical circuitry including the clinometer 11 compares actual readings with a zero reading and displays the difference. In a more advanced form of the apparatus, flexion and/or glide and glide force are measured and displayed.
