PowerShell strings are just .NET strings, so you can:

PS> $x = '-foo-'
PS> $x.Replace('-', '&')
&foo&

...or:

PS> $x = '-foo-'
PS> $x.Replace('-foo-', '&bar&')
&bar&

Obviously, if you want to keep the result, assign it to another variable:

PS> $y = $x.Replace($search, $replace)

But this solution also match for -content and replace it to &content.

The built-in -replace operator allows you to use a regex for this e.g.:

C:\PS> '-content-' -replace '-([^-]+)-', '&$1&'
&content&

Note the use of single quotes is essential on the replacement string so PowerShell doesn't interpret the $1 capture group.

If you DO need your expressions inside double quotes, like when combining with $variables, you can escape the capture group dollar signs ($) by preceding them with a backtick (`)
