Yes, although if you have a few million and access to a daily MRI you can even heal a PCL this way. See the Connor McDavid documentary "Whatever it Takes". For my wife, it was strict bracing at specified angles with forced stretching to retear the tendon at periodic intervals as it healed. She was on advil and a cryo cuff immediately after injury which really helped. I'd recommend having a cryo cuff on hand or a plan to quickly get one if knee injuries are likely in your future. Look into red light therapy for ankle, for example: https://a.co/d/7CPLFkl https://a.co/d/7CPLFkl
