The treatment, which was devised by the hospital's inpatient clinical lead physiotherapist Jackie Stayton, has reportedly cut the average length of stay by ten per cent.
It involves special exercises both before and after the operation, as well as regular assessment of the patient's walking.
Ms Stayton commented: "Clinical evidence shows that fit, strong patients get better more quickly than patients who are less fit so we decided to invite patients to an exercise class six weeks before the operation."
The clinical lead revealed that exercises have to be tailored to suit individuals, as each patient progresses at a different speed.
"We also helped them perfect a normal posture and gait, which is sometimes quite difficult after surgery," she added.
