Source: Brakkee, E. M., et al. Surgery and Behavioral Testing in the Tibial Neuroma Transposition Model in Rats. J. Vis. Exp. (2023).This video demonstrates a procedure to generate a rat tibial neuroma transposition (TNT) model. After exposing the tibial nerve in the hind leg of an anesthetized rat, transect the nerve. Next, create a subcutaneous tunnel, thread the severed nerve through the tunnel, and suture it in place. In the absence of a target for reinnervation, disorganized axonal...

Currently any kind of vascularized composite allotransplantation depends on long-term-immunosuppression, difficult to support for non-life-critical indications. We present a new porcine tibial VCA model that can be used to study bone VCA and demonstrate the use of surgical angiogenesis to maintain bone viability without the need of long-term immune-modulation.

The Trial Balance

A trial balance is a fundamental financial statement that provides a snapshot of a company's accounts and their balances at a specific point in time. It serves as an essential tool for verifying the accuracy of financial records by ensuring that the total debits equal the total credits. Typically prepared at the end of an accounting period, a trial balance lists all ledger accounts in the order they appear, with debit balances in the left column and credit balances in the right column. The two...

Its main value is that it lets the surgical team evaluate the prepared tibial side together with a matching femoral trial before choosing the permanent implant. This combined assessment reveals whether alignment, joint-line position, soft-tissue balance, stability, range of motion, and patellar tracking work together. The findings provide a functional basis for refining component selection.
Each adjustment changes how the trialed components relate to the surrounding knee structures and to one another. Altering size, rotation, or thickness can help the surgeon address findings related to alignment, stability, joint-line position, motion, or patellar tracking. This flexibility allows problems to be identified and corrected during the operation rather than after permanent implantation.
A need for adjustment may be indicated when the trial assessment shows poor alignment, an inappropriate joint-line position, inadequate soft-tissue balance, instability, restricted range of motion, or unsatisfactory patellar tracking. These findings are evaluated with the matching femoral trial, so the decision reflects overall knee mechanics rather than the tibial side in isolation.
The tibia is first prepared, after which the temporary tibial component is inserted and assessed with a matching femoral trial. The surgeon then evaluates alignment, joint-line position, soft-tissue balance, stability, range of motion, and patellar tracking. If the mechanics are not satisfactory, the trial’s size, rotation, or thickness can be changed before selecting the permanent implant.
Surgeons use the assessment after preparing the tibia and before selecting and implanting the permanent component. This timing is important because it creates an opportunity to test the proposed reconstruction under intraoperative conditions. Adjustments can therefore be made while component choices remain changeable, helping address mechanical problems before they become part of the final replacement.
In total knee arthroplasty, tibial trialing supports more accurate component selection and helps optimize the reconstructed joint’s mechanics. By checking alignment, stability, motion, soft-tissue balance, joint-line position, and patellar tracking before implantation, it may help reduce the risk of postoperative instability, malalignment, or restricted movement. Its relevance is therefore both procedural and functional.
