I am concerned you may be developing a "cyclops" lesion, or scar tissue in the front of the knee following ACL reconstruction.  This may be a result of incomplete resection of the residual ACL stump, or the postoperative scar tissue. Either way, this forms a block to extension.  You should see your surgeon, who may modify your PT or suggest a minor arthroscopic procedure to remove the cyclops.
