Description

These surgeries require specialized implants (like long stems or hinged components) and increased operative time to reconstruct the joint, manage soft tissue deficiencies, and restore stability. Key Aspects of Complex TKR Indications: Severe arthritis, severe valgus/varus deformities, failed prior knee surgery, ligamentous instability, or bone loss. Techniques: Specialized techniques include using longer stems for stability, metal augments to manage bone loss, and specialized Rotating hinge prostheses for severe ligamentous laxity. Procedure: Involves removing existing hardware, addressing structural defects, and potentially using bone grafts. Recovery: Often involves a longer rehabilitation period than primary surgery.
