Karly Dawson, PA-C attended a Sports Medicine Physician Assistant Course hosted by Arthrex in Naples, FL this July. The conference brought in PAs from all over the U.S. to provide education and experience in treating common surgical knee and shoulder injuries.

The cadaver lab provided an opportunity to practice surgical techniques, including knee and shoulder arthroscopy, ACL and MPFL reconstruction, graft harvesting and preparation, meniscus repair, rotator cuff repair and bicep tenodesis, and AC reconstruction. Karly was very grateful and inspired to participate in this valuable learning opportunity.

Approximately 16-17 yrs ago Dr. Karch put my right hand back together. I fell off a roof from 20' & walked away with just a busted wrist, and partially separated AC joint. I continually think about how much I have to be thankful for from that accident.

Well I've had no issues, and have used this right hand in my daily construction trade. I am for ever grateful for your skilled hand -by giving me the ability to continue to passionately play my guitar, have a successful construction business all while still living an extremely dominate physical life style.

I've kept that x ray on my wall these last 16 years looking at it like a work of art all the while playing my guitar and reminding my self how quickly our lives can change and lose the ability to do what we love. As I've gotten older I've gained more perspective/appreciation on what's important and what I place value on. We all use our hands in this life, and with the work of your hands, my right one still gets to do what I love.

Here's a picture of your work, it always looked like art to me- just a little constant reminder to cherish what we can do and what we get to do in this world.

Thank you so much!!

Dr. Karch was also a co-recipient of the Adelina Award, the highest honor awarded for humanitarian work in the Philippines, for his work leading the Forward Surgical Team that deployed to Tacloban City in the Philippines just after the super storm Typhoon Haiyan (Yolanda) made landfall.4

Dr. Karch has received two letters of commendation from the President of the United States of America. Internationally, Dr. Karch is recognized for his instruction in mass casualty medicine based upon his real experiences in disaster zones.

MOI Team Publishes Study on Improved Pain Relief After Total Knee Replacement

September 21, 2016

Drs. Parisky, Harkins, Karch and Gilmer’s article titled as “Periarticular Liposomal Bupivicaine Injection Decreases Length of Stay, Pain Scores, and Opioid Usage After Total Knee Arthroplasty When Compared to Femoral Nerve Block” was accepted for publication in the Journal Progress in Orthopedic Science. The study confirmed the effectiveness of a new postoperative pain management regimen used at Mammoth Hospital to shorten length of hospital stay and decrease the need for narcotic pain medications after knee replacement surgery. Research associate Sarah Lang of the MOI Bishop team was fundamental in the success of the manuscript’s publication.

Mammoth Orthopedic Institute Hosts First Annual Sports Medicine Course

August 25-27, 2016

Mammoth Orthopedic Institute in partnership with Mammoth Hospital recently hosted its first annual course and lecture series on the practice of Orthopedics developed by orthopedic surgeons, Michael Karch, Timothy Crall, and Brian Gilmer.

This "meeting of the minds" for all things orthopedics included participants from all over the country - doctors, nurses, physician assistants, physical therapists, and athletic trainers.

The goal of the Mammoth Sports Course wasn't merely to rehash the same PowerPoint presentations given by experts at various meetings, but to critically evaluate the indications, techniques, successes, and failures involved in the treatment of complex problems in which no clear evidence-based guidelines exist.

Reviews are in and have been overwhelmingly positive by all attendees, so you can count on our Mammoth Orthopedic Institute surgeons to build on this course in the years to come! Great work team!

Bigger is not always better

Aug 30, 2016

Doctors usually think bigger hospitals offer better surgery. Turns out, we’re wrong.

During surgical training I got a call from my mother with an unusually focused question. She had just returned from the doctor’s office where she was told she needed to have her gallbladder removed. Her question to me was simple enough — “Where should I have my surgery?”

Like nearly every health care provider, I’m quite used to having family members ask for medical advice. Usually it is in other fields I do not practice, and I often guide them back to the doctor they’re already seeing.
