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 neck...

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

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 group...

Summary

Treating fractures near total knee replacements is challenging due to implant interference and bone condition. This review covers incidence, classification, and treatment for these difficult periprosthetic knee fractures.

Area of Science:

Orthopedic Surgery
Biomedical Engineering
Trauma Management

Background:

Periprosthetic fractures of the knee, particularly around the distal femur, proximal tibia, and patella, present significant treatment challenges.
Factors like compromised fixation, comminution, osteoporosis, prior surgeries, and the knee implant itself complicate management.

Purpose of the Study:

To review current concepts on the incidence, classification, treatment options, and outcomes of periprosthetic knee fractures.
To provide a comprehensive overview for orthopedic surgeons managing these complex cases.

Main Methods:

Literature review of existing studies on periprosthetic knee fractures.
Synthesis of current knowledge on epidemiology, diagnostic criteria, and therapeutic strategies.

Main Results:

Fractures adjacent to total knee arthroplasty implants are difficult to manage due to anatomical and biological factors.
Various fixation techniques and surgical approaches exist, each with specific indications and limitations.

Conclusions:

Effective management requires careful consideration of fracture pattern, bone quality, and implant status.
Optimizing outcomes for periprosthetic knee fractures necessitates a tailored treatment approach based on current evidence.
