Hip replacements are one of the NHS's highest volume procedures, with ~14,000 operations per month before the onset of the COVID-19 pandemic. Delays to surgery can have significant implications; meaning increasing levels of pain and worsening quality of life. As of January 2021, following the initial waves of the COVID-19 pandemic, 58,000 people had waited an average of 25 additional weeks for their total hip replacement. The results of the study will hopefully help treating clinicians identify patients in whom there may be further deterioration if surgery is significantly delayed.

---|---|---|---|---|
Primary | The primary aim of this study is to evaluate the factors, including obligate external rotation, that are associated with risk of progression in hip OA. | The Deterioration Index (mm/week) will be calculated as the difference in average joint space width for the affected hip in AP X-Ray images taken at least 12 weeks apart, divided by the number of weeks between the X-Ray images assessed. The relationship with the parameters collated (age, BMI, KL grade, presence of OER) and DI will be evaluated to work out a cut-off value for high or low DI as part of the validation study.
The DI will also be evaluated as regards a relationship to the OHS and EQ5D to assess if there is a correlation with metrics used to assess subjective outcome in this patient cohort. |
Participants attend clinic for a one-time clinic visit. | |
Secondary | 1-Develop a simple grading system based on the aforementioned results, to evaluate the feasibility of aiding clinicians in prioritising patients for THR. | The secondary aims of the study will be evaluated by analysing the suitability of a grading system for risk of progression of hip OA, based on factors that lead to the highest DI values.
The presence of OER will be evaluated and evidence of correlation to the photographic internal rotation angle, as well as quality of life scores will be assessed. |
For approximately for 1 year, through study completion. | |
Secondary | 2-Validate the assessment of obligate external rotation remotely using a camera. | Participants will first be examined for their maximum hip internal rotation possible when supine with hip and knee flexed at 90 degrees.
They will then be asked to sit in front of a camera placed at a height 2 to 3 feet (0.6 to 0.9 m) off the ground and stand 6 feet (1.8 m) away(6). Patients will be asked to spread their feet as far apart from each other whilst sitting straight with hips and knees at 90 degrees. A photograph will be taken of their neutral position, and another with their best attempt at internal rotation. The internal rotation angle obtained along with the photo number will be documented on a data collection sheet with a hospital sticker, BMI, oxford hip score and EQ5D score completed that day. At the end of the day, this information shall be collated & transcribed onto an excel spreadsheet for subsequent x-ray and photo review & measurement, anonymisation and analysis. |
For approximately for 1 year, through study completion. |
