A North East knee specialist has earned international recognition for his expertise in treating complex sports injuries.
Mr Andrew Cattell, an orthopaedic surgeon at University Hospitals Tees, received the Certificate of Excellence in arthroscopic knee surgery from the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA).
He is the first surgeon in Britain—and one of only six worldwide—to achieve the full ESSKA certification.
Mr Cattell said: "I am deeply honoured to achieve a certificate of excellence from ESSKA.
"This milestone represents years of hard work, intense assessments and the invaluable opportunity to work alongside leading European surgeons who developed the very techniques being examined.
"It has been a highly rewarding journey, and I am excited to bring these innovative techniques to our hospitals to directly benefit our patients and enhance their long-term recovery outcomes."
The certification required completion of five advanced courses, each covering a different area of knee surgery.
These included anterior cruciate ligament (ACL) reconstruction, multifilament reconstruction, meniscal surgery, patellofemoral surgery and osteotomy.
Each course involved a written postgraduate exam, a detailed case study and surgical video, and a two-day practical assessment in an arthroscopic cadaveric laboratory.
Mr Cattell has already introduced several advanced procedures at University Hospitals Tees.
These include performing the first meniscal transplant at the University Hospital of Hartlepool in 2025.
He is also working on introducing arthroscopic trochleoplasty, a minimally invasive technique to reshape the front of the knee without major surgery.
Mr Cattell said: "The ESSKA certification process has equipped me with the advanced knowledge, surgical precision, and clinical insight needed to treat the most complex sports knee injuries."
Named North East Orthopaedic Trainer of the Year in 2024, Mr Cattell has also qualified as an ESSKA Certified Teacher and secured a place on the ESSKA faculty.
This new role will enable him to mentor junior consultants internationally.
He now hopes to gain ESSKA accreditation for University Hospitals Tees, aiming to establish a world-class teaching centre in the region.
