Sir I had the revision acl reconstruction with Prtellar tendon graft from my un-injured knee 6 weeks back (no LET and meniscus repair) done due to tunnels mal position in first surgery (1st surgery done 2 years back). 1.  I started weight bearing walking from 3 days  I'm getting sharp pain at anterior medial corner with click and loud pop up while starts flexing and remove weight from operated knee while walking.( Clicks observed in every step). 2. There is a laxity in my knee with negative pivot shift. Is there any serious issue???
