Knee Joint

2.1K
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...

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Ankle Joint01:10

Ankle Joint

1.7K
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...

    Summary

    Unicompartmental knee arthroplasty (UKA) offers improved outcomes for knee osteoarthritis. Success hinges on careful patient selection, optimization, and advanced surgical techniques for better knee biomechanics and recovery.

    Area of Science:

    • Orthopedic surgery
    • Biomedical engineering

    Background:

    • Unicompartmental knee osteoarthritis is increasingly treated with Unicompartmental Knee Arthroplasty (UKA).
    • UKA success depends critically on patient selection and pre-operative optimization.
    • Advancements in prosthesis design and surgical techniques have enhanced outcomes.

    Purpose of the Study:

    • To discuss key factors for successful Unicompartmental Knee Arthroplasty.
    • To review indications and patient selection criteria for UKA.
    • To highlight surgical pearls for various UKA types.

    Main Methods:

    • Review of current literature on Unicompartmental Knee Arthroplasty.
    • Analysis of factors influencing patient selection and surgical technique.
    • Discussion of biomechanical principles and post-operative recovery.

    Main Results:

    • Appropriate patient selection is paramount for optimal Unicompartmental Knee Arthroplasty outcomes.
    • Improved prosthesis designs (fixed/mobile bearing, medial/lateral) enhance knee biomechanics.
    • Refined surgical techniques contribute to faster recovery and better functional results.

    Conclusions:

    • Unicompartmental Knee Arthroplasty is a viable option for select knee osteoarthritis patients.
    • Meticulous patient assessment and surgical technique are crucial for success.
    • Ongoing innovation in UKA continues to improve patient recovery and outcomes.
