Research summary
The study aims to explore the impact on function of a rehabilitation pathway with no restrictions in patients following total hip replacement (THR).
Following THR, patients are advised to follow a restricted rehabilitation pathway. This involves avoidance of movements increasing the risk of hip dislocation, commonly known as ‘precautions.’ These are;
• No bending past 90 degrees at the hip
• Use raised chair
• No twisting in either standing or sitting
• No crossing legs
• Sleep on their back
• Use elbow-crutches / mobility aidHowever, emerging evidence casts doubt on the impact of precautions on dislocation. Previous research has explored factors influencing dislocation, such as surgical technique, type of hip replacement and precautions. The evidence is mixed in terms of what exactly constitutes an unrestricted pathway with many studies being selective regarding which of the precautions were omitted.
In existing research there is no consideration that patients find adherence to precautions challenging with potential non-adherence. However in patient forums they report difficulties managing activities of daily living due to the imposed precautions. A shift away from precautions will have the potential to improve patient function, pain and quality of life.
Present research suggests further work is required due to a lack of evidence enabling traditional precautions to be excluded following THR.
The proposed research plans to explore the differences in two randomised groups of patients using questionnaires and patient diaries for 12 weeks after surgery.
One group will follow usual care of a restricted pathway following precautions, and the second an unrestricted pathway with no precautions.The study sites are two specialist Elective Orthopaedic Centres in Greater Manchester. The study will involve patients admitted for THR in the care of a surgeon agreeing to participate.
The study is unfunded however is endorsed by the British Orthopaedic Society and The Association of Trauma and Orthopaedic Chartered Physiotherapists.
