J.R. Smith’s mysteriously wretched season continued against the Bulls Wednesday night and Knicks coach Mike Woodson acknowledged the reigning NBA Sixth Man award winner may never get back to last season’s form.

Smith is coming off surgery on a chipped patellar tendon and torn meniscus in his left knee. He hasn’t shown enough quickness on defense and offensively can’t find a rhythm on his jumper or an ability to get to the free-throw line.

“J.R. has had his struggles,’’ Woodson said Thursday on his ESPN Radio show. “I don’t think he’s still 100 percent. I don’t know if he’ll ever be this season based on the surgery he had this offseason. I have to be patient with him. I still expect him in the minutes he plays, he’s got to contribute more.”

Smith is averaging just 11.1 points in 30 minutes — his production down seven points per game from last season. He’s shooting 34.4 percent. During Chicago’s comeback on Wednesday, Smith also committed a silly foul in blatantly shoving Kirk Hinrich to the floor while fighting through a pick.

Woodson, who tried starting Smith for three games last month, has recently talked about reducing his minutes because he has complained of knee soreness. There is also a movement to have Amar’e Stoudemire on the court in crunch time to aid Carmelo Anthony as Smith’s shooting struggles continue. Stoudemire hit the go-ahead, tiebreaking shot to key the win over the Bulls, and after the game said his goals are “through the roof.’’
