Torn and Repaired Meniscus - thoughts/input - When can i climb again?!?

My husband had surgery for a bucket handle meniscus tear Oct 2022. They removed some of the meniscus.

We hiked up to Suicide rock 2 weeks after his surgery and he was climbing just fine. The hiking back down hurt.

Just 2 months later he sent a 5.13.

I’d start that rehab on it sooner rather than later. 2 years out and his knee is doing great.
