Posture Guy- After your first accident on the go kart - Any injury is not that well know - its exact structure and the tissue/cartilage strength are not know from an MRI. That structure and strength depends on where splits are in the cartilage. These splits can be difficult to see in MRIs. With a labrum tear why should a person expect that it would function for tennis which is stressful to the shoulder?
In 2011, I kept playing when I knew my knee was having joint issues. I left the courts a few weeks later from sudden pain unable to play - a meniscus injury. That was my turn for a dumb move in order to play tennis.
If someone has a labrum tear how should they interact with their Dr and, in your opinion, what should they do about playing tennis?
