hi doctor I am a 30 year old male, i suffered sports injury to my knee while playing Basket ball. neglected it for almost a year then finally underwent Arthroscope in which damaged cartilage was cut. it reduced my pain a lot but not fully. now i have started getting the same kind of pain in my other knee. It pains badly while climbing steps and certain movements of the knee joint is painful. can any medicine help in repair building cartilage? i was a very active person before this injury but now i am leading a sedentary life because of the pain. i was told by some one about Cartigen Forte. is it of any help for my age.?
I strongly suggest you to visit physical therapist and do some treatment with them.  As well also do MRI once again for the knee and check the level of damage based on that the therapist will be able to guide you well how much time it can take to recover.  As well also take glucosamine tablets which help for healing of cartilage in knee. Here you have given name of cartilage fort tablet even this one is also helpful.  But I suggest taking something from Natural supplement range. And also do good enough of knee strengthening exercises.  Progress gradually in that.  And I am sure you will be fine. Hope this was useful.  Take care.
