Key result
HPV-77DK12 rubella vaccination was associated with recurrent episodes of knee stiffness in 11 children, providing evidence that chronic joint disease can be a sequela of rubella immunization.

Does HPV-77DK12 rubella vaccination cause chronic arthropathy in children?
This case series provides evidence that chronic joint disease can be a sequela of rubella immunization.
Answers are grounded in this paper and cite their sources.
Case series links rubella vaccine to synovial hypertrophy and chronic arthropathy; leaves open causality and relevance to modern formulations.
Eleven children suffered recurrent ipisodes of knee stiffness ("catcher's crouch syndrome") after receiving HPV-77DK12 rubella vaccine. One was evaluated by arthroscopy and the synovium was found to be hypertrophied posteriorly and to protude in folds into the intercondylar notch and lateral joint space. Culture for rubella virus was unsuccessful. The author's observations provide evidence that "catcher's crouch syndrome" is a synovial disease and that chronic joint disease can be a sequela of rubella immunization.

Spruance et al. (1977) conducted a case report in Recurrent episodes of knee stiffness ("catcher's crouch syndrome") (n=11). HPV-77DK12 rubella vaccine was evaluated on Recurrent episodes of knee stiffness ("catcher's crouch syndrome"). HPV-77DK12 rubella vaccination was associated with recurrent episodes of knee stiffness in 11 children, providing evidence that chronic joint disease can be a sequela of rubella immunization.
