Hypothesis
Should GPs refer patients with suspected internal derangement of the knee for MRI or to an orthopaedic specialist?
Conclusion
The DAMASK trial aims to determine the best referral pathway for patients with knee issues to improve outcomes and reduce costs.
Supporting Evidence
- MRI is an accurate diagnostic test for detecting meniscal and cruciate lesions.
- 85% of meniscal lesions and 90% of healthy menisci found at arthroscopy are detected with MRI.
- Negative MRI findings could allow GPs to reassure patients and avoid unnecessary referrals.
Takeaway
This study is trying to find out if it's better for doctors to send patients for an MRI or directly to a knee specialist when they think there's a problem with the knee.
Methodology
A multi-centre pragmatic randomised trial with two parallel groups comparing MRI access versus referral to an orthopaedic specialist.
Potential Biases
Potential biases in GP referral practices and patient selection may affect the outcomes.
Limitations
The trial may not account for all variations in waiting times and referral practices across different regions.
Participant Demographics
Participants aged 18 to 55 presenting with knee issues in general practice.
