Surgical Outcome Score (SOS) data was collected from May 2017 through January 2019:
- The Visual Analog Pain Scale (VAS) records a patient’s self-reported pain level on a scale from 0-10, where 0 is no pain and 10 is the worst pain possible.
- The ASES Shoulder Index Score records a patient’s self-reported outcome using a combination of pain level and shoulder function on a scale from 0-100, where 0 represents maximum pain and inability to perform 10 activities of daily living and 100 represents no pain and no difficulty performing 10 activities of daily living.
Scores are recorded prior to surgery and at designated intervals following surgery. Ideally, graphs using the Visual Analog Pain Scale should show a downward trend over time (as pain decreases) and graphs using the ASES Shoulder Index Score should show an upward trend over time (as shoulder function increases and pain decreases).

IN THE NEWS
Dr Hartzler has been an incredible advocate and partner in my care and recovery.- TSAOG Patient Survey
I saw Dr Hartzler after I thought I'd strained my R shoulder while tugging my seat belt too hard. He told me I tore my rotator cuff and would require surgery. He performed procedure in August 2015 and walked me through entire, 6-week recovery process and what to expect during that time. I'd recommend Dr Hartzler to anyone!- Elsa M., Healthgrades
I saw Dr. Hartzler for severe shoulder pain and the inability to basically function with my left arm. His initial diagnosis was frozen shoulder. For several months we tried injections and ultimately determined that surgery was the best option. I found him to be an excellent doctor - both in terms of listening and not pushing for surgery immediately. His surgical skills and team are exceptional and the results are fantastic. Within a week I was a able to start physical therapy and am very pleased with my progress. I would highly recommend Dr. Hartzler to anyone requiring shoulder or elbow guidance and help.- Linda Caldwell, Vitals
Had shoulder surgery 4 years ago. ROM was shot and I was in constant pain. Went to see other orthopedic surgeons and was told I would need a shoulder replacement. Pain management doctor suggested Dr. Hartzler. Said he was the " Michael Jordan" of shoulders. He was wrong. He is actually the Michael Jordan and Dr. J of shoulders. Dr. Hartzler placed skin graft between joint in place of my worn away cartilage. He also repaired my SLAP repair by doing tenodesis. Everything has worked out great.- Scott Y., Healthgrades
