BACKGROUND: Around 20% of knee replacement have an unsatisfactory outcome. Pre-operative physiotherapy and education have been proposed to improve post-operative outcomes. OBJECTIVES: This systematic review evaluated whether these factors improved length of stay and patient reported outcomes after knee replacement surgery. DATA SOURCES: Medline, Embase, CINAHL, Cochrane Central Register of Controlled Trials, PsycINFO and PEDro were searched on the 1st January 2013. STUDY SELECTION OR ELIGIBILITY CRITERIA: Randomised or quasi-randomised studies assessing either pre-operative education or physiotherapy on patients undergoing a planned total or partial knee replacement were included in the review. Only studies with a control group receiving a defined standard of pre-operative care were included. RESULTS: Eleven studies met the inclusion criteria set. Two studies analysed the effect of pre-operative education, seven pre-operative treatment by a physiotherapist and two studies used both factors. No study found significant differences in validated joint specific patient reported outcome measures. The education studies found a decrease in pre-operative expectation and an improvement in knowledge, flexion and regularity of exercise. Two studies found an improvement in muscle strength in the group treated by a physiotherapist at three months. The combination of education and physiotherapy was shown to reduce patient length of stay and cost in one study. CONCLUSION: The evidence reviewed is insufficient to support the implementation of either pre-operative education or physiotherapy programmes. The combination of pre-operative education and treatment by a physiotherapist may reduce the medical costs associated with surgery.
