For post injury &/or surgery I recommend Vibrant Health Joint Vibrance. It's the most comprehensive & well dosed formula (powder) I've found to date. It's not cheap, but it works if you pump it in.
For tendon injury &/or inflammation try cissus &/or Joint Fixx - keep in mind cissus doesn't seem to have the same benefit for everyone. Joint Fixx is: avocado - soybean oil, turmeric & hyaluronic acid.
For joint support & controlling inflammation Infinite Labs Joint Support is great as it contains Boswellia, cayenne & turmeric + building blocks.
For daily maintenance & joint lubrication Vital Labs Joyful Joints - contains building blocks + cissus & Hyaluronic acid.
For connective tissue repair & joint maintenance Now Joint Support Powder as it contains collagen + building blocks.
MK-677 I would also recommend, if it doesn't cross your HGH line. Also Ostarine is great for connective tissues (don't be fooled into thinking you've healed before time though) & Stemtech SE3 (this has worked for me before).
For ointments Christophers range is amazing...and I've tried a few. Use the Complete Tissue & Bone ointment after physio sessions to help draw out the bruising & clear the damaged cells, this will speed up the healing process by allowing fresh cells to proliferate in the repair zone faster & in greater numbers. Use with either of:
Sen Sei Menthol cooling balm, for cool heat, or
Cayenne heat balm for warmth, to help with stretching to increase range of motion and boost circulation.
Sombra is an Aloe Vera based cooling gel, get the heat one with cayenne in it for added anti-inflammation. Keep it in the fridge & if you overdo it or are experiencing pain slap some of that on, especially before bed - it works a treat for pain relief (if it's cold where you are use the Cayenne balm instead...it also clears sinus pretty quickly!)
Aside from that, as Jiigzz mentioned, slow & steady strengthening exercises, lots of stretching & range of motion movement.
