In algebra and number theory, Wilson's theorem states that a natural number n > 1 is a prime number if and only if the product of all the positive integers less than n is one less than a multiple of n.
Clement's congruence-based theorem characterizes the twin primes pairs of the form (, +) through the following conditions: [()! +] ((+)), +P. A. Clement's original 1949 paper [2] provides a proof of this interesting elementary number theoretic criteria for twin primality based on Wilson's theorem.

The Wilson quotient W(p) is defined as: = ()! + If p is a prime number, the quotient is an integer by Wilson's theorem; moreover, if p is composite, the quotient is not an integer. If p divides W(p), it is called a Wilson prime. The integer values of W(p) are (sequence A007619 in the OEIS): W(2) = 1

In number theory, a Wilson prime is a prime number such that divides ()! +, where "!" denotes the factorial function; compare this with Wilson's theorem, which states that every prime divides ()! +. Both are named for 18th-century English mathematician John Wilson ; in 1770, Edward Waring credited the theorem to Wilson, [ 1 ] although it had ...
Part of Wilson's theorem states that ()! for every prime p. One may easily prove this theorem by Sylow's third theorem. Indeed, observe that the number n p of Sylow's p-subgroups in the symmetric group S p is 1 / p − 1 times the number of p-cycles in S p, ie. (p − 2)!.
The sentence you keep changing doesn't say that every possible proof of Wilson's theorem uses Lagrange's theorem, it says that all the proofs in the Wikipedia article use it. So the parts of your comments about the necessity of use seem beside the point.
