Hyperbaric oxygen for bone, muscle and tendon: where it helped and where it did not, across 19 studies
A systematic review published in August 2026 pooled 19 clinical studies with 612 patients. The most consistent improvements were in avascular necrosis and bone marrow edema. For muscle soreness after exercise, randomized trials found no benefit.
What was studied
The authors searched for clinical studies in people, published from 1996 to January 2026, that used the hyperbaric chamber for bone, muscle, tendon or ligament injuries. They left out studies that combined the chamber with other therapies, transplants, radiation injuries, osteomyelitis, and spine and oral surgery. That left 19 studies with 612 patients.
The studies measured different things, so the authors did not combine the results into a single number. They reviewed them one by one and rated each one’s risk of bias. That is why this review says where improvements are consistent, but not how large they are.
What it found
Avascular necrosis and bone marrow edema: studies reported consistent improvements in imaging, pain and function, especially with longer protocols. Bone injuries used 20 to 80 sessions.
Muscle soreness after exercise: the evidence is limited, and randomized trials found no significant benefit.
Ligaments: limited evidence suggesting a possible benefit for healing. Tendons: inconclusive results.
Safety: adverse events were rare and mild. Most sessions lasted 60 to 90 minutes, breathing 100% oxygen.
What it means for you
Avascular necrosis is the death of an area of bone from lost blood supply, and bone marrow edema is fluid built up inside the bone that shows on an MRI. Those two diagnoses are where the review found the most consistent results, and avascular necrosis is already on the list of 15 indications recognized by the Undersea and Hyperbaric Medical Society.
If what you want is faster recovery after training, the trials that exist found no clear benefit.
For bone, the protocols that worked were long: 20 to 80 sessions. Before you plan a short trip, ask in your evaluation how many sessions your case would need and over how many days.
What it does not say
It gives no effect size, because it did not combine results in a meta-analysis. And while most randomized trials had a low risk of bias, the non-randomized studies had serious or critical bias from confounding and measurement problems.
The authors present the chamber as an add-on to other treatments, and call for better trials in ligaments, muscle recovery and tendons before drawing conclusions.
How it connects to BMC
BMC’s chamber is multiplace, up to 2 atmospheres, with 60 to 90 minute sessions, the same length most of these studies used. Bone necrosis is a hospital indication that BMC Clinic does not treat; if that is your case, discuss it with your treating physician.

Does this apply to you?
A study says what happens on average. What makes sense for you comes out of the evaluation, with your history and your lab work.
