Biography
John T. Kroner, M.D.
General Orthopaedic Surgeon
Dr. John Kroner specializes in surgery and treatment of general orthopaedic problems, such as joint replacement surgery, arthroscopic surgery, fractures, and sports medicine.
Dr. Kroner works with each patient to understand the underlying orthopaedic issues and uses his expertise to treat them – or refer them to the most qualified clinician whose expertise he would entrust with a family member or himself.
I have enjoyed caring for patients with orthopaedic problems for over 30 years. My other interests are family, fishing, cooking, and music.
A Letter of Gratitude and Transition
Dear Patients, Colleagues, and Friends,
After much reflection, I am writing to share that I will be retiring from the practice of orthopaedic surgery. My last day will be
June 11, 2026.
This decision comes with deep gratitude and, admittedly, mixed emotions. Orthopaedics has been more than a career to me-it has
been a calling, a community, and a privilege that has shaped my life in ways I could never have imagined when I began this
journey.
I was fortunate to begin my education here in Milwaukee, attending Marquette University before earning my medical degree at
the Medical College of Wisconsin. I completed my internship and residency at MCW, where I also had the honor of serving as
Chief Resident. Those formative years instilled in me not only a love for orthopaedic surgery, but also the values of teamwork,
humility, and service–principles that have guided me ever since.
In 1987, I joined Orthopaedic Associates, and it has truly been my professional home. Over the years, I have been privileged to
practice alongside exceptional colleagues, and staff, who share a commitment to putting patients first. The 2015 merger with
Blount Orthopaedic Specialists was especially meaningful to me. I was fortunate enough to have met Dr. Blount as a resident, so I
was excited to become part of that legacy. More recently our merger with Wisconsin Bone & Joint, S.C. has continued that
tradition of growth, collaboration, and excellence in care.
One of the greatest joys of my career has been practicing alongside my son, who joined the group 13 years ago. To watch him
care for patients with skill, compassion, and integrity has been among my proudest experiences, both as a physician and as a
father.
To My Patients: thank you for placing your trust in me during some of the most vulnerable moments of your lives. It has been an
honor to care for you and your families. The relationships built over decades–often across generations–are what I will miss the
most.
To My Colleagues And Staff: you are the heart of this practice. Your dedication, kindness, and professionalism are what make it
such a special place to work. I am endlessly grateful for the teamwork, laughter, and support we have shared. You have made
even the most challenging days meaningful.
While I may be stepping away from the exam room, I leave with immense confidence in the future of this practice, and in the
people who will continue to provide outstanding care. I will miss the daily connections, the shared purpose, and the privilege of
serving this community more than words can fully express.
Thank you for allowing me to be a part of your lives and for making my career so fulfilling. It has truly been the honor of a
lifetime.
With sincere gratitude,
John Kroner, MD
