DoDMERB Past Surgery Question

My son had small portion Meniscus removed from his knee in the 10th grade. He wrestled the same year and has played soccer and wrestled his Junior year. My question is, should I get a letter from his Orthopedic surgeon stating he has no physical limitations from his surgery? We don’t want anything to delay or hold him back medically on this physical.

Does anyone have Suggestions or went through this and can help?

Thanks in advance!
