Research summary
VO2 max is the maximum volume of oxygen attainable to a person whilst exercising and is considered a strong indicator of cardiovascular fitness and aerobic endurance. Research has shown that VO2 max levels significantly improve post-surgery, once the patient resumes functional activities, and may be useful in accurately predicting post-operative outcomes.
This observational feasibility cohort study will measure VO2 max prior to and following routine robot-assisted hip arthroplasty surgery and examine its association with outcomes of recovery after surgery. VO2 max will be measured using the Seismofit® System, which is a new method of measuring VO2 max without the limitations of the gold standard cardiopulmonary exercise testing. The device is simply attached to the participant’s sternum using an adhesive patch, and measures vibrations arising from heart beats that are transmitted to the chest, taking around 45 seconds.
The study will also measure pain and functional ability via patient reported outcome measures and objective performance assessments. In addition, participants will be invited to wear activity monitors on their wrist prior to surgery, and for 12 weeks after discharge, to understand changes in physical activity and sleep patterns.
Patients undergoing a robot-assisted hip arthroplasty with Professor Middleton at the Nuffield Health Hospital will be invited to take part in the study. It is anticipated that it will take 12 months to recruit the 30 participants. Participants will have follow-up study visits on day 1 at Nuffield Hospital, and at 3-, 6-, and 12-weeks post discharge at the Orthopaedic Research Institute. Data relating to surgery, discharge and medication will also be taken from routine data collected at Nuffield Hospital. Participants will continue to be followed up clinically as per standard care. Findings from this feasibility study will inform the design of future interventions to improve cardiovascular fitness in patients undergoing hip arthroplasty surgery.
