Fig. 1 A schematic representation of the classification of pain location into anatomical patterns of pain. (A) Participants indicated locations of pain on the Photographic Knee Pain Map (with permission from Elson et al.20). (B) Pain zones were identified using the transparency overlay of the photographic knee pain map, and (C) were subsequently combined into corresponding anatomical regions of pain, which were used to generate pain patterns (with permission from Van Ginckel et al.6). QT = quadriceps tendon, LP = lateral patella, MP = medial patella, PT=patellar tendon, MJLA = medial joint line area, SM=superior medial, LJLA = lateral joint line area, SL=superior lateral, T = tibia. Note that the posterior knee zone or regions are not depicted as a tick box, (A) enabling participants to report pain in the posterior knee (as present or absent).
