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...

Area of Science:

Orthopedic Surgery
Sports Medicine
Biomedical Engineering

Background:

Bone-patellar tendon-bone (BPTB) grafts are standard for anterior cruciate ligament (ACL) reconstruction.
Graft thickness variability impacts ACL reconstruction biomechanics.
Current techniques lack consistent graft thickness control.

Purpose of the Study:

To present the novel "BPTB-plus" technique for arthroscopic ACL reconstruction.
To describe a method for augmenting BPTB grafts to improve consistency.
To address the challenge of unpredictable graft thickness in ACL reconstruction.

Main Methods:

Arthroscopic surgical technique description.
Utilizing a bone-patellar tendon-bone (BPTB) autograft or allograft.
Augmenting the BPTB graft with the gracilis tendon.

Main Results:

The BPTB-plus technique provides a method to enhance graft dimensions.
This technique aims to improve the predictability of graft thickness.
Potential for improved biomechanical properties of the ACL graft.

Conclusions:

The BPTB-plus technique offers a novel approach to ACL reconstruction.
Augmenting BPTB grafts with gracilis tendon may enhance graft consistency.
This technique addresses a key limitation in current ACL reconstruction methods.
