Just checked the records of such stuff that I keep here on my PC & we used Oxytetracycline, an old school antibitoic that according to our Vet is rarely used as a go to anymore... at least as far as fighting infection is concerned.
What it apparently does in a large intravenous dose/doses is act as a calcium blocker which in turn allows the spasming tendons to relax. While sometimes it does takes more than 1 or 2 shots to get the desired effect it always works.

Engemicin (? spelling) is a commercial brand of oxytetracycline so you're both referring to the same drug. It can work incredibly well on contracted feet and fetlocks along with splinting, not quite so effective on contracted knees but still helps
