Humerus fracture. Continue my workouts?

Sir, I had fall in while playing in a mall 2 years ago at humerus. Doctor called it as Supra Condylar humerus fracture. I am 42 years now. Surgery was done 2 years before. X-rays of pre-surgery, post-surgery and present are enclosed. I can extend and fold my right hand. For past ten months, I am doing regular workouts which include lunges, squats, burpees, knee push-ups, dips, elbow plank, mountain climbers, inch worms, jumping jacks, sit-ups, crunches, leg raises, punches etc. in 4 days a week for30 to 40 minutes. I do not feel any pain , rather these workouts did lot of good to me in reducing cholesterol level etc. Sir, while doing knee push-ups, I can hear a 'tik' sound from elbow of my fractured right hand. Also I feel little pain while doing pushups. All other exercises are ok for me. I am worried about the sound and fear if any screws in plates are loose? Could you kindly advise if there is any cause of worry? Can I continue my workouts? Thank you.
