In his current clinical practice, Mr Calciu offers a tailored approach, addressing each patient's specific knee problems, such as sports-related injuries and degenerative knee pathology. He specialises in a wide range of knee surgeries, including biological knee surgery (such as tibial and femoral knee osteotomy, ligament reconstruction, meniscal surgery, and cartilage restoration) in selected cases, as well as knee arthroplasty (partial and total knee replacement) for advanced arthritis, joint preservation surgery and knee arthroscopy.

Throughout his career, Mr Calciu has successfully performed over 820 partial and total knee replacements, more than 400 knee arthroscopic procedures (including meniscectomy, meniscus repair, and ACL reconstruction), and 76 osteotomies around the knee (such as high tibial osteotomy, distal femoral osteotomy, and tibial tubercle transfer). Mr Calciu's work is validated by a National Joint Registry feedback, confirming a commendable five-year revision rate of 0.66% for partial and total knee replacements, showcasing his commitment to delivering high-quality surgical outcomes and patient satisfaction.
