Patient-specific implants are considered as one of the new treatment solutions in the reconstruction of complex bone defects. As shown in the animation below, the use of personalized cones in revision total knee arthroplasty surgeries will be a suitable option to reconstruct bone defects and achieve better fixation.
The doctor referred the patient to Fanavaran Jarah Yar Sharif Company and the process of designing a custom Cone for the patient will be done using the CT scan image, in order to pre-operation planning, to accurately assess the patient’s defect size, according to the treatment plan and the surgeon’s opinion. After the final approval of the surgeon, it will be made of titanium.
The advantages of using custom made cones include the following:
- The design is tailored precisely to the patient’s anatomy and bone contours, eliminating issues such as size mismatches commonly observed in commercially available products (off-the shelf cones).
- Pre-surgical planning and assessment of the existing bone defect size allow potential challenges during surgery to be anticipated in advance. This helps reduce surgery time, reduce surgeon stress, and enhance surgical accuracy.
- The use of diaphyseal and metaphyseal cones enhances the fixation of the knee prosthesis in these regions and allows for the use of shorter stems.
- he porous surface of these implants enhances osseointegration, promotes long-term fixation, and helps prevent stress shielding and loosening.
These implants are made from medical-grade titanium alloy, which offers excellent strength, biocompatibility, and proven osseointegration properties.
