Surgeons participating in the Insall Scott Kelly Adult Reconstruction Fellowship at NYU Langone Health in New York review the evidence for various aspects of total hip and total knee arthroplasty management, summarizing what is known – and what still need to be known – about these practices.
Obesity and Its Effect on Outcomes in Total Joint Arthroplasty
Understanding how obesity may influence outcomes in total hip and total knee arthroplasty patients is important in order to lower the risk of complications in this population. Does that also mean there should be a BMI cutoff for total joint arthroplasty patients?

Pain Management in TKA: Periarticular Injections and Peripheral Nerve Blocks
Most multimodal pain control regimens for total knee arthroplasty patients include a combination of oral medications, periarticular injection of anesthetics and/or analgesics, and selective motor-sparing nerve blocks. What is the evidence for this approach?

The Hip-Spine Relationship: What Hip Surgeons Need to Know
Spinal deformities such as excessive kyphosis and degenerative lumbar spine disease and even prior lumbar fusion can have an impact on the success of a total hip arthroplasty. Here’s what surgeons need to keep in mind when planning and performing hip replacement in patients with spinal pathology.

Examining Orthopaedic Applications for 3D Printing
As the technology of 3D printing improves, it has the potential to revolutionize the practice of orthopaedic surgery. An institution's investment in this technology, the authors say, can allow its surgeons to preoperatively plan complex cases, develop implant designs, and enhance education of residents and fellows.
