Srikanth, who had reached the quarterfinals at Rio Olympics in August, had injured himself in Japan and aggravated a stress fracture on his right ankle during his loss in the Korea Super Series last September.
"My ankle is fine and my body is also totally fine but I can't say I am 100 per cent fit, but still I am fit enough. Of course, I can't really compare my fitness with what I was before the Rio Olympics," the world number 15 Srikanth told PTI.
Srikanth, who had reached a career-best world ranking of three in 2015, had a good run at the PBL where he defeated the likes of World No. 2 Jan Jorgensen and World No. 3 Viktor Axelsen in his four wins for Awadhe Warriors, besides losing to compatriot Ajay Jayaram.

"I am playing well and some of my on-court strokes are at per with the best players but because of the too much rest after the Olympics, I think I need to concentrate on my off-court training to get back my endurance so that I can be there throughout the three games in a match," he added.
"I am really excited because I am playing international tournament after four months or something. I didn't get a four- month break in last 4-5 years so it is a really big break for me. I feel the match practice for PBL is good enough for Syed Modi tournament," he said.
"It is a tough competition for sure. Not only for the foreign players but also for the Indian players who are playing well. I don't have too much expectations from the tournament, I just want to get back my confidence."
"After Lucknow, I will be playing the German and then the All England Championship, so I will get enough time to train for the big tournament," he said.
