CAD files describing testing jigs and clamps compatible with simVITRO biomechanical platform.
PTFJ testing jig: CAD files of the testing jig used in the study of the patellofemoral joint.
Femoral clamp:
- Base: Interface between the ATI loadcell and the femoral ring clamps. Comes in two version: a flat version and an oblique for added flexibility to perform deep knee bend.
- Rings: Rods will need to go through the rings and the femur for added stability. A minimum of four are required to secure the femur. Two M8 bolts are required to fix the two section of a ring together and one is used to secure half a ring to the base.
Tibial clamp:
- Base: Interface between the memory clamp of the simVITRO platform and the tibial clamp.
- Half cylinder clamp: Two halves are required to clamp the tibia. M8 bolts are inserted in the threaded holes until making secure contact with the tibia bone. A minimum of four M4 bolts are required to fix the two sections together. Two M8 bolts are used to secure the formed cylinder and the base.
Patella tracker:
- Plate: Fixed to the patellar bone using two self-taping small screws. Hosts two 5x1mm magnets.
- Tracker holder: hold a marker set using one M4 screw. Hosts two 5x1mm magnets (Warming!!! Poles of holder magnets need to match those of the plate)
- Marker set: 6 unique marker set clusters receiving four reflective markers. Can be replaced by QR code trackers.
ACJ testing jig: CAD files of the testing jig used in the study of the Acromion Clavicle joint.

Clavicle clamp:
- Cylinder clamp: M8 bolts are inserted in the threaded holes until making secure contact with the clavicle. We recommend using a minimum of 6 bolts to secure the clavicle.
Scapula clamp:
- L clamp: An L shaped aluminium bracket is equipped with two M8 bolts. The latter are used to press the scapula against two rotating jaws to accommodate the curvature of the bone. We recommend placing two M8 nuts between the L clamp and the bone against the metal plat to mitigate the bending of the bolts and avoid damaging the testing apparatus.
Hip Resurfacing Implant Loading Cup: CAD files of the testing jig used in the study of the femur flexion under load after femoral head resurfacing.
- Spherical cup: the cylinders interface with the simVITRO memory clamp and have half a sphere indent to fit hip resurfacing implants of the following diameters: 36, 38, 40, 42, 44, 46, 48, 50, 52, and 58mm. We recommend machining these parts using polyethylene or nylon block.
