If subject to the same treatment as the whole specimen, that is the same hydration and freeze and thaw cycles, the tissue may reflect the overall level of tissue degradation. The candidate tissue may be a cartilage sample (with the bone) from the ankle joint. The whole foot will be retained and the cartilage sample tested everyday throughout the whole protocol. A simple compression test may suffice for this purpose. * Pressure sensors need to be calibrated and equivalenced. Robb and Jason will accomplish that this week. Related specifications will need to be populated, including what computer and hardware will need to be used. * Snehal will remove the knee from the freezer on Sunday at an appropriate time (see specifications). * Tara will take care of specimen preparation on Monday. * Craig will take the lead on MRI specimen preparation. * Tara will lead the specimen potting and tibiofemoral testing. The related trajectories will be created before next week. Gravity compensation will also be taken care of this week. One related concern that Ahmet brought up is the reproducibility of the testing. Robb noted the compensation also includes machine effects, including friction induced by the mechanical setup. One option to overcome this issue is to mount the tibia up for the tibiofemoral testing and reverse the knee for the patellofemoral testing only. The patellofemoral testing only needs a passive flexion cycle. It was decided inverting the knee for tibfem testing is the best way to go. * Katie will be in charge of taking pictures and documentation of how the protocols are followed, as well as changes to specifications as they are determined. * Helpers for each task were decided on. * Pilot testing data will populate the OKS004 (or lower if the specimen has not been bought yet), in which the metadata will describe this as a pilot test. Snehal will verify what specimens we currently have. |
