When will I be back to full strength after a 270 degree torn labrum?

6-9 months is common. We often tell patients undergoing more significant labral repair surgery in the shoulder that an extended period of time may be required to reach full functional strength. The rehabilitation process is necessarily a bit slower than would be the process forand isolated anterior repair.
I agree. Recovery time will take about 6 months. If you are returning to a throwing sport, or heavy overhead lifting/activity this may take a bit longer. Be sure to follow the protocol from you surgeon and recommendations from your physical therapist.
4-6 months. Assuming this was a 270 degree repair, it will be four to six months before you could expect full strength.
