About twelve weeks ago i was playing football and jumped up and landed on my knee, it popped quite loudly but after about 5 minutes i could stand a hobble. The next day my knee was swollen but not dramatically and i was limping quite severely for about 3 weeks, i didn't see a doctor until after about 5 weeks and they told me it was simply soft tissue damage, i have been having physio and was going really well, i can run, jump and turn without it feeling unstable and i have full quad contraction and can extend my leg fully, but over the last two weeks my knee still has a bit of swelling and i can also feel a tightness behind my knee which doesn't really hurt but it is uncomfortable. Could anyone please help?
