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...

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...

Summary

Infratubercle anterior closing wedge osteotomy effectively reduced excessive posterior tibial slope in anterior cruciate ligament reconstruction patients. This procedure maintained coronal alignment and patellar height without compromising knee stability.

Orthopedic Surgery
Biomechanics
Radiology

Background:

Excessive posterior tibial slope (PTS) increases graft failure risk after anterior cruciate ligament reconstruction (ACLR).
Anterior closing wedge osteotomy (ACWO) can correct PTS but may affect coronal alignment and patellar height.

Purpose of the Study:

To evaluate radiological outcomes of infratubercle ACWO combined with ACLR.
Specifically assess the influence of infratubercle ACWO on perioperative patellar height changes.

Main Methods:

Included patients undergoing infratubercle ACWO with ACLR for PTS > 12°.
Radiological assessment included hip-knee-ankle angle (HKA), PTS, femoral patellar height index (FPHI), and Caton-Deschamps index (CDI) pre- and postoperatively.
Knee recurvatum was measured preoperatively and at final follow-up.

Main Results:

Significant PTS correction achieved (14.5° to 5.7°, p < 0.001) with no significant HKA change.
No significant change in FPHI or patellar height categories observed.
Knee recurvatum significantly increased (4.9° to 7.8°, p < 0.001).

Conclusions:

Infratubercle ACWO provides precise sagittal correction for PTS without altering coronal alignment or patellar height.
The procedure is effective in managing excessive PTS in ACLR patients.
