My 7-year-old son was kicked in the knee while playing soccer. He complained of pain and swelling, which caused him to limp. After one week the knee pain and swelling are now gone. Is it safe for him to resume his soccer activities?

Resolution of pain and swelling following a trauma to a knee joint is one sign of recovery. In addition, the child should be able to bear weight and move the knee without pain before resuming his soccer activities. If any of these symptoms persist, he should be examined by a physician.
