Study Arms:
- Hyperbaric oxygen therapy (Type: EXPERIMENTAL): Hyperbaric oxygen therapy consists of 30-40 treatment sessions (1 session per day during 5 days per week). During the hyperbaric oxygen (HBO) sessions the pressure will be raised to 2.4 atmospheres absolute in a hyperbaric chamber and patients breath in 100% oxygen during 4 times 20 minutes.
- Usual care (Type: NO_INTERVENTION): Usual care may consist of physiotherapy, analgetics, edema therapy

Based on this trial design, predict the completion outcome and termination type (if applicable).
