Partial Knee Arthroplasty helps you optimize outcomes using the latest best-practice techniques for this increasingly popular procedure. Drs. Keith R. Berend and Fred D. Cushner discuss recent advances and hot topics - such as custom guided implants, biologics, failed PKA, TKA conversion, and more - along with the challenges of choosing the right technique for each patient. The clear focus on surgical techniques, bulleted key points, and procedural videos on DVD and online at website make this comprehensive, practical reference ideal for learning how to achieve the best results.

This title focuses on such area as joint replacement and hip, knee & lower extremity. Efforts to enhance the surgical technique of total knee arthroplasty while avoiding the negative aspects of computer navigation have led to the development of patient-specific cutting guides. In this study, the authors examine the results of 50 TKAs. Detailed MR imaging of each patients knee is obtained along with several slices through the hip and ankle. From these images, proprietary software creates and orients (in space) virtual 3D models of the femur and tibia. Appropriate implant sizes are determined with the help of the software, and virtual bony resections are mapped to help the surgeon accomplish accurate position and alignment. A preoperative plan with visual images is sent to the surgeon for review. Upon approval, rapid prototyping technology is used to fabricate actual models of the patients distal femur and proximal tibia. Also developed are disposable custom guides that will fit precisely on the patients bone to determine accurate pin placement for the standard resection instrumentation of the implant manufacturer. Preliminary results in 50 TKAs show accurate femoral component sizing and restoration of alignment of 4-8 of valgus in all cases. TKA can be performed with custom jigs in truly patient specific fashion, allowing the surgeon to achieve optimal alignment without violating the intramedullary canal.
