Hypothesis
To find out the determinants of a reduced quadriceps strength and to establish a score to screen for it.
Conclusion
A low performance in one of the selected field physical tests associated with age and BMI allows screening for those in whom a measurement of quadriceps strength could be of interest before arthroplasty.
Supporting Evidence
- 58% of patients had reduced quadriceps strength.
- Patients with reduced strength had higher BMI and altered physical test results.
- The predictive model for reduced strength had an AUC of 0.87.
Takeaway
This study found that many patients with knee or hip osteoarthritis have weak thigh muscles, and certain tests can help identify who needs further evaluation before surgery.
Methodology
An observational prospective study measuring various physical and health parameters in patients with knee or hip osteoarthritis before surgery.
Potential Biases
The population studied could be biased by the severity of osteoarthritis at a surgical stage.
Limitations
The study is monocentric, which may limit the generalizability of the results.
Participant Demographics
Mean age was 67 years, with 66% having knee osteoarthritis and 34% having hip osteoarthritis.
