The mystery quadriceps weakness has alluded us for decades. Traditionally femoral nerve block has been vilified as the sole perpetrator. The rediscovery of the forgotten truths around Arthrogenic Muscle Inhibition (AMI) and the influence of surgery and trauma of muscle function has shed new light on this issue. Long-term continuous femoral nerve block may even block the neurological pathway of AMI and enhance recovery of, for example, quadriceps muscle function after total knee arthroplasty. DR. Hari Parvataneni and his colleagues…

Dr. Hari Parvataneni, a prominent orthopaedic surgeon who specializes in joint replacement surgery wrote this interesting editorial on liposomal bupivacaine and separates pseudo-science from real science. He argues that the market penetration of this drug far exceeds the scientific evidence behind it. For at least the past 30 years since 1988 companies sought for this magic bullet, but because not only the effects but also the side effects of such long-acting local anesthetic agents would linger.

Dr. Boezaart wrote this editorial on the sensitive topic of the opioid epidemic that is upon us.

Outpatient shoulder and elbow replacement surgery has been practiced since the early 1990’s. Now, there is a big push for outpatient total joint replacement surgery of the hip and knee as well. Because the patients need their lower extremities to ambulate, this pose some unique and complicated problems. This is the protocol used by the University of Florida orthopaedic surgeons to manage these.
