What Researchers Did
Researchers retrospectively evaluated the efficacy of hyperbaric oxygen therapy (HBOT) in 37 patients with osteonecrosis of the knee (ONK).
What They Found
After 30 sessions of HBOT, 86% of patients experienced improvement in their Oxford Knee Scores (OKS), with all patients showing improvement after 50 sessions. Magnetic resonance imaging one year post-HBOT revealed that edema at the femoral condyle had resolved in 36 out of 37 patients.
What This Means for Canadian Patients
Hyperbaric oxygen therapy may offer a non-invasive treatment option for Canadian patients suffering from osteonecrosis of the knee, potentially reducing pain and improving mobility. This therapy could help resolve edema and improve knee function, providing an alternative to more invasive procedures.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or participants.
Study Limitations
As a retrospective study with a relatively small sample size, these findings may be subject to selection bias and lack a control group for comparison.
