I do my best to keep rehab as simple as possible .
Rebuild capacity any way you can initially, with consideration to stages of healing, pain tolerance and what’s enjoyable too! .
Once capacity has been restored to the tissue, aim to rebuild the whole system AKA The Kinetic Chain
This isn’t achieved through some complex, fandangled single exercise or piece of equipment - it’s done through replicating the meaningful movements you as an individual need to be happy, healthy or competitive
That’s what functional exercise should be!
