Dr. Thomas J Joyce possesses a rich background with 30 years of experience in the field of artificial joints. His extensive research encompasses a broad spectrum of topics within this domain. His contributions range from the inception of artificial joint designs to the creation of innovative testing apparatus for artificial joints where none had existed before. He has also delved into the exploration and evaluation of novel orthopaedic biomaterials and conducted in-depth examinations of artificial joints that have undergone the ultimate test – within the human body. Throughout his career, Dr. Joyce has maintained a close collaboration with orthopaedic surgeons. His pivotal role in identifying and elucidating engineering issues associated with metal-on-metal hips stands out prominently. This began with the scrutiny of the ASR metal-on-metal hip, which has been described as a ‘tragedy for many patients’ in the New England Journal of Medicine. His commitment to this area extended to other iterations of artificial hip joint designs. Driven by his expertise, he contributed substantially to the UK government's select committee inquiry into the regulation of medical implants. This investigative work, aimed at ensuring patients' access to the safest implants, remains ongoing. Presently, his research is highlighted by high-profile endeavours in spinal implants, knee joint replacements, and wrist joint replacements, all driven by the overarching goal of enhancing patient safety and implant efficacy.
