Bones of the Lower Limb: Tibia and Fibula

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Muscles of the Leg that Move the Foot and Toes

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

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...

Background:

The popliteus tendon is a key stabilizer of external knee rotation, often injured in posterolateral corner injuries.
Isolated popliteus tendon injuries are rare, typically caused by rotatory mechanisms, leading to instability and pain.
This case involved a concomitant injury to the proximal tibiofibular joint.

Purpose of the Study:

To describe a surgical technique for popliteus tendon and proximal tibiofibular joint reconstruction.
To restore external rotation stability and overall knee function in patients with these specific injuries.

Main Methods:

Preoperative examination under anesthesia to assess external rotation and pathology.
Peroneal nerve neurolysis followed by semitendinosus and gracilis autograft harvest.
Anatomical tunnel reaming and graft fixation for popliteus tendon and tibiofibular joint reconstruction, with anterior tibial traction.

Main Results:

Anatomic popliteus tendon reconstruction significantly reduced external rotation laxity in a cadaveric study.
The procedure also decreased varus laxity, anterior tibial translation, and internal rotation.

Conclusions:

This technique effectively restores external rotation knee stability through anatomical reconstruction.
Reconstruction of the popliteus tendon and proximal tibiofibular joint enhances static knee function and stability.
