What We Know about Knee Injuries in Hockey, and What We Do and Don't Know about Miro Heiskanen's Return

Let's all learn something today

On January 28, Mark Stone collided with Miro Heiskanen’s left knee. Initially, the hope was that Heiskanen wouldn’t be out for an excessive amount of time, but after some imaging was done, Heiskanen had knee surgery in New York on February 4.

While the Stars haven’t given specifics about the nature of the knee injury, there are some pretty logical deductions you can make from watching the hit itself. .

Here’s what we know for sure:

• This injury (or injuries, if damage was done to multiple parts of the knee) was caused by a hit to the outside of the knee

• Surgery was required

• Jim Nill said last week in an interview with the DLLS crew that the plan is for Heiskanen to return “sometime in the first round.”

• Heiskanen was not yet skating as of last week

To supplement that knowledge, we can refer to a still image from that injury showing just how far Stone bends Heiskanen’s knee inwards:
