Hi, guys first of all I would like to thank you for great informations you put up. Few days ago I tweaked my back, couldn’t deadlift at all, so I just did some tempo squats and tempo rack pulls in folllowing days (as you often recommend).Three days after “injury” I hit PR (162,5 kg x 4) for paused squat. 
Finally my question. In this study The locked knee - PubMed about the locked knee and lack of evidence for mechanical block. Actual quote from abstract: 16% of the knees remained locked following the induction of anaesthesia. What type of rehab would you recommend for patients whit locked knee? Would surgery be a good option?
Thank you, Filip
Historically, mechanical symptoms, or “locking” have been indications for knee arthroscopy. More recent research calls this practice into question:

Hey @Filip_the_Ortho-doc , glad to hear you are feeling better with your back. Great question regarding the “mechanical symptoms” conundrum. I discussed this issue here: Loading....
Mechanical symptoms is a rather abstract phrase that we don’t have a good definition for. Currently, my clinical stance is to intervene with appropriately dosed exercise to the area and then load to tolerance. I’ll need time to review the article you linked but @Matthew_Rupiper_PT , linked several relevant recent articles on the topic.

Filip,
I would also look at this article.

Just because 16% of knees remained “locked” under anesthesia does not imply that there still would not have been progression with conservative care.
