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.

One constraint of preclinical research in the field of bone repair is the lack of experimental control over the local mechanical environment within a healing bone lesion. We report the design and use of an external fixator for bone repair with the ability to change fixator stiffness in vivo.
FAQs
The correction changes the limb’s mechanical axis, meaning the line through which body weight is transmitted during standing and movement. By repositioning that axis, the procedure reduces excessive force on the damaged knee compartment and directs more weight toward healthier cartilage. This redistribution addresses the mechanical source of uneven joint stress while retaining the patient’s native knee.
An opening wedge and a closing wedge are controlled ways to alter the shape and alignment of the upper tibia. Either approach changes the limb’s mechanical axis, which determines how weight crosses the knee. The resulting realignment can shift loading away from a damaged compartment and toward cartilage that remains healthier.
Varus or valgus alignment can concentrate mechanical stress unevenly across the knee, particularly when disease affects one compartment. Correcting that alignment changes the path of weight transmission and can reduce pressure on the damaged area. This principle explains why tibial osteotomy may relieve pain and support function in selected cases of unicompartmental osteoarthritis.
The procedure may be considered for selected patients with unicompartmental knee osteoarthritis, varus or valgus deformity, or malunion after an injury. These conditions share an alignment problem that can alter how forces pass through the knee. Correcting the tibial relationship may address that abnormal loading while preserving the native joint.
Expected goals include reducing knee pain and improving function by correcting the alignment responsible for uneven compartment stress. Because the native joint remains in place, the operation may also delay or avoid knee replacement in appropriate patients. These outcomes reflect a joint-preserving strategy rather than removal and replacement of the affected knee surfaces.
A malunion can leave the tibia in an abnormal alignment, changing the mechanical axis of the leg and the way forces reach the knee. Realignment through tibial osteotomy can correct that relationship and reduce uneven stress across the joint. In this setting, the procedure applies the same joint-preserving principle to a deformity arising after injury.
