Hypothesis
Does the release of short rotator tendons affect intracapsular pressure and pain in osteoarthritic hips?
Conclusion
The study found that short rotator tendons do not significantly affect intracapsular pressure or correlate with pain in severe osteoarthritis.
Supporting Evidence
- Release of the short rotators did not change intracapsular pressure in most positions.
- The only significant change was an increase in pressure at 45° flexion after release.
- No correlation was found between intracapsular pressure and pain.
Takeaway
The study looked at whether cutting some tendons in the hip would change the pressure inside the joint or make it hurt less, but it didn't find any big changes.
Methodology
Intracapsular pressure was measured in patients undergoing total hip arthroplasty before and after short rotator release.
Limitations
The study was limited to patients with severe osteoarthritis, which may affect the generalizability of the findings.
Participant Demographics
Patients with severe osteoarthritis undergoing total hip arthroplasty.
