Hi Mifsuddk - welcome to the RPT thread - from what you have described and shown on the photographs, it looks like you have sustained a RPT tear as against a Ruptured Patella Tendon, where the tendon is torn from the patella (kneecap). Am surprised that no surgery was required to put the tendon together.
I have meanwhile sent you a set of documents which I have compiled over the years, although the rehab maybe to strenuous if you have sustained a partial tear. I would have thought that you could obtain a better opinion in Copenhagen, which is not too far from Jutland.
Keep posting
Take care
