Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Sports Medicine
Knee Biomechanics

Background:

Posterolateral corner (PLC) injuries are complex knee ligament injuries.
Current surgical techniques for PLC reconstruction can be invasive or complex.
There is an ongoing need for simpler, effective PLC reconstruction methods.

Purpose of the Study:

To introduce and evaluate a novel, mini-invasive surgical technique for knee posterolateral corner reconstruction.
To demonstrate the feasibility of using a single tendon graft for simultaneous reconstruction of multiple PLC structures.

Main Methods:

A mini-invasive technique utilizing a single tendon graft for simultaneous reconstruction of the lateral collateral ligament, popliteofibular ligament, and popliteal tendon.
Emphasis on precise tibial, fibular, and femoral tunnel creation and graft placement.
Attention to protecting the peroneal nerve during the procedure.

Main Results:

The described technique is technically straightforward to perform.
Clinical experience suggests the technique is effective for PLC reconstruction.
The method offers a potentially simpler and effective surgical option.

Conclusions:

This mini-invasive, single-tendon PLC reconstruction technique provides a viable and effective alternative for patients requiring surgical repair.
The procedure simplifies the reconstruction of complex PLC injuries.
Further adoption of this technique may enhance treatment options for PLC injuries.
