Does a hyperbaric oxygen chamber help with recovering from a PCL injury?

PCL Hyperbarics. Hyperbaric medicine is not used for this type of injury. There is no proof that it will help you in this case.
No. There is no good evidence that hyperbaric oxygen helps from recovering from a PCL tear. The PCL is a very stout ligament with tremendous scarring capability. It will heat its just that it may not heal tightly.
No. Hyperbaric oxygen promotes the healing of open wounds when the tissue is devitalized or has a poor blood supply because of diabetes, infection, radiation, or trauma. Although it helps with delayed or compromised healing of open wounds, it won't accelerate the normal rate of healing of a PCL injury if you already have a good blood supply with none of the above risk factors for poor healing.
