Based the following report, KD appeared to have been seeing an orthopedic surgeon who thought it was only Grade I tear in his calf. Apparently, he did not need surgery if his diagnosis was correct. Therefore, I keep wondering who is in charge of KD's treatment plans and what kind of medical care has been rendered since then. Based on my 30+ years of clinical experience involving treating hundreds of calf tears, I believe KD should have been back on court at least by Game 4 if not earlier had he received timely and adequate physical therapy, massage therapy, or acupuncture, etc.
An orthopedic surgeon might be knowledgeable and effective for bones and ligaments. KD's strained calf was originally diagnosed as Grade 1, now maybe a Grade 1-plus, or a Grade 2. I'm not trying to be judgmental, however, this really doesn't sound a typical expert opinion with any confidence and assertiveness.
Therefore, in my opinion, KD would better start to seek someone who has more experience in soft tissue injuries if he'd want to return to this Finals and continue to advance his career.
