LOST THE GAME. FIRST K.D. AND NOW KLAY.>>YEAH. WE’RE JOINED BY THE DOCTOR WHO WORKED THE TEAM FROM 2001 TO 2009. WE HAD YOU HERE TALKING ABOUT K.D.’S SITUATION. NOW IT’S KLAY. IF YOU’RE HERE ANYMORE, WE’LL HAVE TO GET YOU AN ABC7 PIN.>>WHAT WE HAVE HERE IS A MODEL OF THE KNEE. BASICALLY, THERE ARE FOUR BONES THAT MAKE UP THE KNEE. WE’LL FOCUS ON TWO, THE FEMALURE AND THE FIBIA. THEY ARE HELD TOGETHER BY THE FOUR MAIN LIGAMENTS. THE COLLATERAL LIGAMENTS ON EITHER SIDE AND THEN THIS HERE. THIS IS THE ONE THAT WE ALWAYS TALK ABOUT. THE ONE THAT’S SO IMPORTANT. PART OF THAT IS WHAT GIVES IT THE ATHLETE THE SENSE OF STABILITY. IF YOU WATCHED KLAY, HE SAID MY KNEE WENT LIKE THIS. IT IS A COMMON EXPENSE A PLAYER HAS WHEN THEY INJURE THEIR KNEE. WHAT KLAY DID WHEN HE WENT UP FOR THAT DUNK, HE GOT HIT FROM BEHIND. HE GOT OFF BALANCE AND FELL BACKWARDS. HIS FOOT CAUGHT JUST ENOUGH. AS HE PULLED ON HIS QUAD ACCEPT MUSCLE, THE TENSION JUST SNAPPED.>>WHAT IS TYPICAL RECOVERY TIME?>>TECHNICALLY MORE DIFFICULT THAN AN ACHILLES’ BUT IT IS THE SAME TIME. NINE MONTHS TO A YEAR. NINE MONTHS IS WHEN WE LET ATHLETES GET BACK TO PLAYING.>>IN THE CASE OF KEVIN DURANT, HE PREVIOUSLY A CALF INJURY. WE DON’T KNOW IF THERE IS ANY CAUSE AND EFFECT OF WITH KLAY, HE HAD A HAMSTRING INJURY. AND THEN THIS HAPPENS. ANY CONNECTION BETWEEN THE INJURIES?>>NO. I DON’T THINK SO. THERE IS NO CONNECTION WHATSOEVER. IF YOU LOOK AT THAT REPLAY, THERE IS CLEARLY A MECHANICAL DISADVANTAGE THAT HIS KNEE HAS WHEN HE LANDS AND IT HAS NOTHING TO DO WITH THE HAMSTRING NOT BEING STRONG ENOUGH.>>AN ACHILLES’ TENDON IS PRETTY RARE.>>IT’S AMAZING TO ME THAT BOTH OF THESE INJURIES DON’T HAPPEN MORE COMMONLY, CONSIDERING THE SIZE OF THESE PLAYERS AND THE SPEED AND ATHLETICISM THAT THEY’RE PLAYING THE GAME AT. A TREMENDOUS FORCE THROUGH THEIR BODIES. EVERY STEP OF THE GAME. ITS AMAZING THAT THEIR ARE NOT MORE INJURIES.>>WHICH IS MORE DIFFICULT, THE ACL REHAB OR THE ACHILLES’ TENDON? THEY’RE BOTH DIFFICULT IN THEIR OWN WAY. CERTAINLY THE ACL RECONSTRUCTION IS DIFFICULT. AFTER A COUPLE WEEKS THEY’RE BOTH DAUNTING. ONCE YOU GET BACK TO IT. THE LEVEL OF PLAY THAT THEY NEED TO BE PREPARED FOR.>>SOME PLAYERS ARE ABLE TO COME BACK MORE QUICKLY OF OTHERS WITH FOR INSTANCE DERRICK ROSE, HE TOOK LONGER TO GET HIS FEET UNDERNEATH HIM. THESE INJURIES ARE ALL VERY VARIABLE. IT IS UNIQUE FOR EVERY PLAYER. MY HOPE IS TO SEE THEM BACK ON THE COURT FOR THE PLAYOFFS.>>I HOPE WE DON’T SEE YOU ANY TIME SOON. WE LOVE WHEN YOU COME IN.>>AS A
