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...

Area of Science:

Orthopedic Surgery
Musculoskeletal System
Surgical Procedures

Background:

Knee joint fusion (arthrodesis) is a salvage procedure for severe knee destruction.
It aims to eliminate pain and provide a stable, plantigrade limb.
Indications include infection, instability, and post-traumatic arthritis.

Purpose of the Study:

To provide a comprehensive video guide on knee arthrodesis techniques.
To illustrate critical steps for successful surgical outcomes.
To serve as an educational resource for orthopedic surgeons.

Main Methods:

The video details patient positioning and surgical approach.
It highlights techniques for bone preparation and joint surface management.
Methods for achieving stable fixation and bone grafting are shown.

Main Results:

The procedure aims for solid bony union of the knee joint.
Successful fusion leads to pain relief and functional limb restoration.
Post-operative management and rehabilitation are crucial.

Conclusions:

Knee arthrodesis is an effective option for managing debilitating knee conditions.
Mastery of surgical techniques is essential for optimal results.
This video serves as a valuable training tool for surgeons.
