Ligaments will not heal together the knee will kind of remodel itself and maybe stabilize a little. The knee will never be 100%. esp if the meniscus is damaged. Just stay away from any strenuous activity as that joint will be very prone to arthritis. watch the other knee as the majority of dogs will injure the other one in the next year or 2. I had my 11 yr old dog done about 10 yrs ago(she passed away last year at 20 1/2 yrs) The vet I work with has had tplos done on her shorthair, both knees within a year or so of each other.
