Effect of combined hyperbaric oxygen therapy on anterior cruciate ligament reconstruction

Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedanterior cruciate ligament injury
Date of first enrollment01/12/2021
Target sample size80
Countries of recruitment
Study typeInterventional
Intervention(s)Hyperbaric oxygen (HBO) therapy. For the HBO combination group, HBO will be started the day after ACL reconstruction. A total of 10 times in a row excluding Saturdays and Sundays. The HBO protocol should be 2.0-2.5 ATA for 60-120 minutes, and a protocol that can reduce oxygen toxicity and other complications as much as possible and ensure efficacy will be adopted. We will use the HBO protocol implemented at our hospital, that is, "15 minutes pressurization, 60 minutes 2.0 ATA oxygen, 15 minutes decompression" with extremely few adverse events. The scientific basis is based on "Physiology and Medicine of Hyperbaric Oxygen Therapy". HBO discontinuation shall meet the discontinuation criteria.


Primary OutcomeEvaluation of maturation of the anterior cruciate ligament by MRI
Secondary OutcomeQuantitative evaluation of peripheral blood bone marrow-derived cell., Physical findings (knee joint swelling, muscle atrophy, range of motion, anterior movement amount, half-month movement amount over time), knee function evaluation, patient-standing knee function evaluation., Safety (adverse events, side effects)

Key inclusion & exclusion criteria

Age minimum>= 14age old
Age maximum<= 45age old
Include criteria1) Men and women aged 14 to 45 at the time of consent, 2) Patients with traumatic anterior cruciate ligament injury (whether fresh or old), 3) Patients with consent from the substitute
Exclude criteria1)Patients with inflammatory disease 2) Patients with intra-articular fracture and osteochondral injury 3) Patients using bone metabolism regulators 4) Patients receiving hyperbaric oxygen therapy within 1 month prior to obtaining consent 5) Patients with compound ligament injury who require surgical treatment for ligament injuries other than the anterior cruciate ligament 6) Patients with a history of surgical treatment on the affected knee 7) Patients with physical or mental illness who cannot perform MRI examination 8) Chronic lung disease, chronic sinusitis, nasal polyps, upper respiratory tract inflammation and other sinus stenosis have been pointed out, pneumothorax history, other laryngological diseases, etc. 9) When it is judged that HBO continuation is not preferable due to the exacerbation of the underlying disease 10) Patients found to be pregnant
