After completing his basic medical training at the University of Adelaide in 1986, Dr Penta entered the Family Medicine Program, working as a General Practitioner for two years before embarking on a career in orthopaedic surgery. He returned to study and was awarded the higher degree of Master of Surgery in 1996, and obtained a Fellowship of the Royal Australasian College of Surgeons in 1997. Dr Penta then travelled extensively in 1998, visiting centres of orthopaedic excellence in the UK, Sweden, Germany and Italy before commencing private practice. He is a Fellow of both the Royal Australian College of Surgeons and the Australian Orthopaedic Association, applying best practice by accessing and contributing to resources of these organisations.

NOTICE: Orthopaedics SA is closing soon

Doctors will cease consulting patients at Orthopaedics SA from 1 June 2026 and Orthopaedics SA will also be closing down permanently from this date. We want to make sure all of our patients understand what this means for their ongoing care and any medical records held by Orthopaedics SA.

What is happening to my records? Your records will transfer to your surgeon’s new practice on 1 June 2026, so they remain accessible to them as your treating doctor. If your surgeon is retiring, we will transfer your records to the new practice and surgeon they have nominated to continue your care.

What if I don’t want my records transferred? You have the right to opt out. To do so, please contact our rooms:

  1. on 8267 8267 during our business hours of 9.00 am to 5.00 pm (SA time), Monday to Friday; or
  2. by replying to this email: info@orthosa.com.au; or
  3. in person, at your usual Orthopaedics SA clinic,

on or before Friday, 1 May 2026 to discuss your options. We will need to verify your identity, before discussing your records with you. If we do not hear from you by that date, we will proceed with the transfer as described above. We encourage you to speak with your surgeon well ahead of this date, to obtain details of the new practice and how it will handle your personal information.

What if I have more questions? Please contact our clinic directly using the number you already have on file.

Thank you for being a patient of Orthopaedics SA.
