Tape all broken bone (7)
I believe the answer is:
patella
'bone' is the definition.
(I've seen this before)
'tape all broken' is the wordplay.
'broken' is an anagram indicator.
'tape'+'all'='tapeall'
'tapeall' with letters rearranged gives 'PATELLA'.
(Other definitions for patella that I've seen before include "A pallet (anag.)" , "Knee bone" , "Kneecap (anatomy)" , "The formal kneecap" , "positioned on each knee" .)
