Brief Summary

This study is looking at the impact of giving patients precautions, or restrictions for movement, when undergoing a total hip replacement. Have of the participants will receive precautions, while the other half will not receive any precautions.

Detailed Description

Patients undergoing hip replacements are often told by health care providers to avoid specific positions and activities to decrease the risk of their hip dislocating following their surgery. This, however, results in patients becoming more fearful of moving and leads to limitations in their function and decreased quality of life. Previous research has shown that hip dislocations following surgery are most commonly attributed to poor implant position rather than the actions of the patients. Teaching precautions takes up healthcare resources and may use finances that are not necessarily required. This study aims to compare groups with half receiving precautions and half not receiving precautions, to assess the impact of precautions on the patients' quality of life.

Primary Outcome Measures

Name	Time	Method
Change in Oxford Hip Score	Week before surgery to 6 months after surgery	Assess function of the hip

Secondary Outcome Measures

Name	Time	Method
Canadian Patient Experience Survey - Inpatient Care (CPES-IC)	At 2 weeks after surgery	This will measure the patients' experience.
Change in Tampa Scale for Kinesiophobia	Week before surgery to 6 months after surgery	This assesses kinesiophobia, using a 17 item scale with each item using a 4 point Likert scale . The final score is the sum of all questions except for 4, 8, 12 and 16 which has their score inverted before being added. The final score ranges from from 17-68 points with 68 being the highest degree of kinesiophobia.
Change in Forgotten Joint Score	6 weeks after surgery to 6 months after surgery	This measures awareness of a replaced joint
Change in EQ-5D-5L	Week before surgery to 6 months after surgery	This measures general health
