Abstract
Nine patients have been reviewed at an average period of 22 years after a Watson-Jones tenodesis performed for chronic instability of the ankle. Only three patients had complete relief of symptoms. Two favourable early results deteriorated 7 and 10 years after operation. Radiographic examination revealed full correction of both anterior and lateral instability of the talus in only two cases. Talar tilt was controlled more successfully than increased anterior drawer movement. Long-standing instability was associated with the formation of marginal exostoses, the severity of which appeared proportional to the degree of instability.
