“…Combining other constraints of cosmetic surgeries [IW,It1,De], the cosmetic surgery conjecture has been confirmed for many cases, such as, knots with at most 17 crossings [De], composite knots [Ta2], cable knots [Ta1], 2-bridge knots [IJMS], pretzel knots [SZ]. In fact, the number of purely cosmetic surgeries, even if exists, is finite in the following sense; for a given b > 0, there are only finitely many knots that admit a purely cosmetic surgery whose braid index is less than or equal to b [It3].…”
