Revision TKA with Sleeves

Description

In this surgical demonstration video, Eytan Debbi, a hip and knee replacement surgeon at the Hospital for Special Surgery, conducts a thorough walkthrough of a revision total knee replacement procedure using a cadaveric specimen. The video starts with an introduction, outlining the objectives of the demonstration, which includes removing a prior total knee prosthesis, assessing the patient's anatomy, and performing the revision with sleeves for improved fixation.



The procedure involves several key steps:

1. **Exposure Techniques**: The surgeon first focuses on exposure techniques to gain access to the knee joint, showcasing tips for effectively removing the previous implant using various surgical instruments to ensure adequate visibility and access.

2. **Assessment of the Prior Implant**: Eytan evaluates the stability and anatomical challenges presented by the current knee replacement, noting the condition of flexion and extension.

3. **Removal Process**: Detailed descriptions of the tools and methods for removing the existing prosthesis are provided, including the use of saw blades and osteotomes to carefully dislodge the implant while preserving surrounding bone.

4. **Reconstruction of the Knee**: After successful removal, Eytan details the reconstruction of the tibial plateau and femur, emphasizing the importance of having a strong foundation for the new implant.

5. **Broaching and Component Placement**: The surgeon describes the broaching process for the femoral sleeve and tibia, utilizing various tools designed to ensure proper alignment and fit of the new components. Throughout the video, Eytan emphasizes maintaining flexion gaps and assessing soft tissue integrity for optimal surgical outcomes.

6. **Final Evaluation**: After implant placement, the stability and range of motion of the knee are assessed, ensuring appropriate alignments and tension in flexion and extension before concluding.



Eytan wraps up the demonstration by discussing post-operative care and encouraging any inquiries for further learning. This demonstration highlights advanced techniques in knee replacement surgery, focusing on precision and anatomical understanding for effective patient outcomes.
