CORRECTION
==========


Young M A, Cook J L, Purdam C R, *et al*. Eccentric decline squat protocol offers superior results at 12 months compared with traditional eccentric protocol for patellar tendinopathy in volleyball players ([Br J Sports Med 2005;39:102–5](http://bjsm.bmj.com/lookup/volpage/39/102)). The total percentage scores in the final line of figure 4A are incorrect; the correct totals are 6% and 94%. We apologise for this error.
