Bethlehem • Kutztown • Lehigh Valley

Dr. Michael D. Hendel, MD, PhD, is a board-certified orthopedic surgeon and Assistant Professor of Orthopedic Surgery at St. Luke’s University Health Network. He completed both his residency and his fellowship in Sports Medicine & Shoulder Surgery at Hospital for Special Surgery in New York — ranked the nation’s #1 orthopedic hospital by U.S. News & World Report for more than 14 consecutive years.

He served as Assistant Team Physician for the NFL New York Giants (2017–2018) and spent five years on faculty at the Mayo Clinic College of Medicine (2018–2023), where he also served as Research and Education Chair (2019–2023), before returning to the Lehigh Valley. He remains on the sidelines today as team physician for the Reading Royals (ECHL professional hockey), the Lehigh Valley IronPigs (Triple-A baseball), and Liberty & Freedom High School football (PIAA District XI), and serves as tournament physician for the PIAA State Wrestling Tournament.

Dr. Hendel holds a PhD in Cardiac Physiology from the University of Minnesota, completed a postdoctoral fellowship there, and earned his MD from the Cleveland Clinic Lerner College of Medicine on a full academic scholarship. He has authored 18 peer-reviewed publications in journals including JBJS, JSES, American Journal of Physiology, and Clinical Orthopaedics and Related Research, plus three book chapters in ISAKOS ACL Surgery. He is a reviewer for the American Journal of Sports Medicine and the HSS Journal, and a member of AAOS, AOSSM, the Orthopaedic Research Society, and the American Physiological Society.

“I believe patients deserve a clear understanding of their condition and a well-defined plan to get them back to the activities that matter most to them.”

1ACL Reconstruction

Arthroscopic reconstruction using BTB, hamstring, or quadriceps tendon autograft with rigid fixation and milestone-based rehab.

2Meniscus Repair

Tissue-preserving arthroscopic repair — prioritized over meniscectomy in appropriate candidates to protect the joint long-term.

3Partial Meniscectomy

Outpatient arthroscopic treatment for irreparable tear patterns with an accelerated return to activity.

4Cartilage Restoration (OATS / MACI)

Osteochondral autograft transfer and cell-based cartilage restoration for focal articular defects, preserving the native joint.

5PCL & Multi-Ligament Reconstruction

Frequently Asked Questions

Referral requirements vary by insurance plan. Many plans allow direct access to orthopedic specialists, while others require a referral from your primary care physician. Our office staff can verify your specific plan requirements when you call to schedule at (484) 526-1735.

Recovery follows a structured, milestone-based protocol: independent walking by 4–6 weeks, jogging at 3–4 months, sport-specific training at 5–6 months, and return to competition at 8–12 months. Dr. Hendel monitors objective criteria at each stage before advancing activity. Individual timelines vary based on graft selection, sport demands, and biological healing.

Yes. Non-operative management is the first line of treatment for the majority of musculoskeletal conditions — physical therapy, corticosteroid and hyaluronic acid injections, PRP therapy, bracing, and activity modification. Surgery is discussed only when conservative treatment has not achieved adequate improvement or when the injury warrants operative management for the best functional outcome.

HSS has been ranked the #1 orthopedic hospital in the United States by U.S. News & World Report for over 14 consecutive years, with one of the highest surgical volumes in the country and subspecialty-focused faculty. Dr. Hendel completed both his five-year residency and his sports medicine fellowship at HSS — a depth of training at a single elite institution that is uncommon among surgeons practicing in the region.

New patient consultations are typically available within one to two weeks, and acute injuries and fractures can often be accommodated within 24–48 hours — same-day appointments are often available when Dr. Hendel is in the office. Call (484) 526-1735, schedule online through St. Luke’s, or submit a request through the form below. Please bring any existing imaging (X-rays, MRI) to your appointment.

Yes. Dr. Hendel evaluates and treats athletes across all age groups. Injuries in pediatric and adolescent patients require particular attention to skeletal maturity and growth plate status — his sports medicine fellowship training and professional-athlete experience ensure a high standard of care at every age and competition level.

Dr. Hendel participates with most major carriers through St. Luke’s University Health Network, including Aetna, Blue Cross Blue Shield/Highmark, Cigna, Geisinger Health Plan, Medicare, United Healthcare/Optum, TRICARE, and Workers’ Compensation.
