Wrightington Hospital's status as a Centre of Excellence in the treatment of musculo-skeletal disease has its origins in the seminal work of Professor Sir John Charnley , who pioneered hip replacement surgery involving the techniques of low-friction arthroplasty and also innovative advances to counter post-operative infection.The first ever hip-replacement operations were performed at Wrightington in the early 1960s. Wrightington as grown and now performs more joint replacement and revision surgery than any other hospital in the UK. ( see data section)
