Background
The collapse of the tibial plateau surface or the change in the mechanical axis results in an increase in the pressure per unit area that exceeds the capacity for articular cartilage regeneration, which is known as traumatic arthritis.
Experiments prove that when the joint surface collapses by more than 1.5mm, the pressure in the joint changes obviously; when the thickness exceeds 3mm, the local pressure is obviously increased, and when the collapse and the varus and valgus deformity of the joint cause instability of the knee joint, the prognosis is worse.
Biomechanical properties of 4 different fixation systems were determined on the split-fracture depressed tibial plateau fracture model by cadaver experiments: the fracture specimen is respectively fixed by 4 internal fixing methods such as an L-shaped supporting steel plate, 4 subchondral screws with the diameter of 3.5mm combined with an anti-sliding steel plate, an L-shaped supporting steel plate combined with cancellous bone filling, and 4 subchondral screws placed on the steel plate. The results show that: the strength of the 4 fixing materials is not obviously different on the whole, and the local compressive resistance of the fixing system combined with the subchondral screw is obviously improved, so that a theoretical basis is provided for the application of the subchondral screw to the combination of the central depressed tibial plateau fracture.
The scholars at home and abroad find out through the biomechanical analysis of the subchondral screw of the collapsed articular surface that:
1. the internal fixation is closer to the articular cartilage, and the smaller volume can provide larger compressive stress resistance;
2. the plurality of small-diameter screws are superior to screws with larger diameters in the aspect of biomechanics of resisting the collapse of the tibial platform;
3. the multiple screws with small diameters can increase the fixing area of the fracture, disperse the fixing stress and improve the fixing effect;
4. the bamboo raft type fixation of the plurality of small-diameter screws is superior to the fixation of the large-diameter screws; and the double-row (even three-row) bamboo raft design has more biological advantages.
How to design a better support articular surface of novel shin bone platform outside coaptation board, especially to old age, osteoporosis, fracture smash with the displacement degree great, and can bear a burden the technical problem that shin bone platform coaptation board earlier is the urgent need to solve of wound orthopedics.

The proximal end of the incision extends proximally posteriorly along the inter-articular line, anteriorly around the Gerdy tuberosity, and laterally distally along the tibial tuberosity. The skin and subcutaneous tissues are cut open, the iliotibial band and the tibialis anterior are stripped in front of the fibula, the lateral column is exposed, the joint capsule is cut open, the meniscus is pulled up, the articular surfaces of the lateral column and the posterior lateral column are observed, the displaced articular surfaces are reset, and the kirschner wire is temporarily fixed. For those with the collapse of the joint surface, bone grafting is performed.

For the displaced fracture with crushed and collapsed tibial plateau lateral post, after the fracture is reset, a small incision at the posterior lateral side of the tibial plateau needs to be assisted, namely a longitudinal small incision with the length of 4.0-5.0 cm is made downwards along the inner side edge of the biceps femoris from the joint level, after skin and subcutaneous tissues are cut, the common peroneal nerve is touched along the inner edge of the biceps femoris and the rear part of the small head of the fibula, the common peroneal nerve is not exposed but protected, the outer edge of the lateral head of the gastrocnemius is retracted inwards, and a joint capsule and the tibial plateau lateral post are exposed.
