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...

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...

Muscles that Move the Leg

Muscles that Move the Leg

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

Summary

Rotating hinge knee prosthesis shows positive short-term outcomes for severe knee deformities. Further long-term studies are needed to confirm sustained benefits and safety in total knee arthroplasty patients.

Area of Science:

Orthopedic Surgery
Biomedical Engineering

Background:

Severe knee joint deformity and instability often necessitate complex reconstructive procedures.
Total knee arthroplasty (TKA) aims to restore function and alleviate pain in patients with debilitating knee conditions.

Observation:

This study evaluated 17 patients with severe knee deformities undergoing TKA with a rotating hinge knee prosthesis.
Preoperative assessments included pain levels, disease duration, underlying diagnoses (osteoarthritis, rheumatoid arthritis, traumatic arthritis), and functional scores (HSS).

Findings:

The rotating hinge knee prosthesis demonstrated significant improvements in HSS scores and range of motion postoperatively.
No major complications such as deep vein thrombosis, pulmonary embolism, or nerve palsy were observed, with one case of superficial infection managed successfully.

Implications:

The rotating hinge knee prosthesis appears to be a safe and effective option for managing severe knee joint deformities in the short term.
Long-term follow-up is crucial to fully ascertain the durability and sustained efficacy of this prosthesis.
