Rotating Hinge Knee ( RHK ) for Dislocated Spacer by Dr. Anoop Jhurani

Description

This video features Dr. Anoop Jhurani discussing the revision of a spacer to a rotating hinge prosthesis (RHK) for a patient with a persistently infected knee joint. The presentation highlights the complex case of a knee that has undergone multiple surgical interventions, including explantation and the placement of a spacer that has dislocated. Dr. Jhurani emphasizes the importance of meticulous soft tissue dissection and careful management of neurovascular structures during the procedure, particularly due to the complications stemming from the dislocated spacer and the patient's obesity.



The surgical steps are detailed, from the medial parapatellar incision made to access the knee, to the careful removal of the dislocated spacer, which requires a deep understanding of the anatomy to prevent further damage to surrounding tissues. The protocol also covers the preparation of the tibial and femoral components of the RHK prosthesis, ensuring a snug fit and correct alignment to accommodate the gaps created by previous surgeries and ligament compromise. The video showcases the practical application of techniques to achieve an optimal fit and proper alignment of the new prosthesis, with a focus on minimizing additional surgical trauma, particularly in revision scenarios.



Final assessments of the surgical outcome reveal good alignment and stability of the newly placed prosthesis, accompanied by negative cultures for infection - a vital indicator after two prior infections. The aim of the operation is not only to restore function but also to prevent future complications from infection, which Dr. Jhurani describes as a critical concern given the patient's history. He wraps up the video expressing hope for a successful recovery and stable joint function.
