Strong center with jelly knees?

Pinhead setback for Sixers'Bynum by John Smallwood, Daily News Sports Columnist

The main idea of this article is that 76er's center Andrew Bynum got hurt while bowling. He was out from practice and plays with the sixers because he injured his right knee and couldnt play on it. Despite that fact Bynum went bowling and after bowling he hurt his good knee and claims he doesn't know how it happened.
 

Details/Evidence I have on this article is when Bynum answered a question for interviewers he said "I didn't do anything [while bowling]. I didn't twist it or fall or nothing. [The left knee] got big [after bowling]." He may be telling the truth and really didn't do anything, Then again he could be hiding something he doesn't want to tell interviewers. Another detail i picked up from this article is when Bynum told interviewers that his doctor told him that both of his knees were in a "weakened cartilage state." However of course on Friday, Bynum left out the small detail that he had hurt the left knee while bowling a week earlier.
 

In my opinion I think the center was foolish for going bowling for many reasons but I'll only state 3. My first reason is because the sport of bowling requires bent knees in proper form for one thing and Bynum knew he had a bad knee already yet he decided to play anyway. My second reason is because if you're supposed to be at home resting and trying not to damage that knee anymore why would you even think about going bowling? In my opinion that was a rediculous move. My third and final reason is that if I was him I would've just stayed at home trying to rest and allow my knee to heal a bit unless I have to go in for a check up or something but other than that I'd rest as much as possible so I could get back on the court as fast as possible.

 
Honestly there isn't any connections I can make because I've never went through anything like this before.

 
However this article did help me to think more deeply about the topic because I just think to myself with someone with such a critical condition in his knee why would Bynum go bowling just to mess up his other knee instead of just staying at home like I said and resting."
 
My only question now is what is Bynum and the 76ers going to do about Bynum and his weakened knees? Because that isn't a good way to step out on the court unless you're just looking to hurt yourself.
