Sounds like a good plan. It ought to be a good deal better by then even if it may take even longer to fully heal.

I've had a small flap tear myself. Maybe still do, not fully sure. Initially I had a larger medial meniscus horizontal tear that was repaired (February 2023), but a small part of it ended up retearing after 8 months. The initial tear went from the red/vascular zone to the white/avascular zone and the retear is supposedly in the white/avascular end. Probably had just not become strong enough at that point, if it ever would've have. I was already cleared to lift heavy weights, run and do one legged plyometrics. But in hindsight I should've probably taken it easier and progress more slowly into these plyometrics and avoid deep flexion for a little longer. To give the repair more time to heal while strengthening the leg muscles. The retear happened when I put the knee in full flexion (which I had also done a number of times already). While the knee didn't feel normal yet at this point, this was unexpected.

Based on the MRI the retear was thought to be a flap tear. In the posterior horn. IIRC it was roughly the same size as yours. It bothered me a good while and even caused a mechanical issue. Whenever I would flex the knee past a certain point (as said this is how the retear also happened) sth would go/shift out of place. Like the tibia would shift or buckle a bit. And when I unflexed the knee it would pop back in place. This would happen at least for 1½ months until I stopped even testing this and waited to get an MRI and see the ortho. This ended up taking a good while, and in the meantime I experienced some inflammation and swelling. Finally after 4 months or so I got the MRI and saw the ortho for the results. He also tested the knee for this mechanical issue and it no longer happened. So some improvement had taken place during these 4 months. The ortho also said I would have no limitations at this point. This was in February 2024, 1 year after the repair and 4 months after the retear. After a month or so I then tried doing some relatively light sports and the knee became inflamed and swollen again. But this time the inflammation and swelling would not subside even with daily RICE. Ultimately after a few months I was given a cortisone shot on the knee and this took care of the inflammation in just a few days. This was end of May 2024. After that I was able to get back to the gym again to continue to strengthen the knee and things have slowly gone for the better. I've experienced some lesser inflammation here and there but those have subsided either with RICE or a topical anti-inflammatory gel. Occasionally I would feel sth inside the knee even if not necessarily painful, so I'm not sure if the tear has ever fully healed or not. But the knee is now working quite well. I can even do sports. I'm older than you (42 by the time of the injury) so probably not healing as quickly anymore either.

The one thing that may be different in your case is the "displaced" part. Hopefully it will not cause any problems. I have no knowledge on how well such cases can or cannot heal. My ortho said back then (in February 2024 when I got the MRI results for the retear) that small fragments might also be smoothed out organically, from using the knee. And then be flushed out by the body. Or alternatively they may also heal. If not, then the option is to go inside for a cleanup (debridement). This would've been the final move in my case if I would've continued to experience notable issues. Based on my own experience I reckon one thing you should try to avoid is very deep flexion, since that puts a good amount of stress on the posterior horn of the meniscus. And also avoid twisting the knee. For some time. Try to keep the tear stable and avoid placing much stress on it. But also continue various rehab exercises to maintain mobility and to strenghthen the leg/knee. This includes also stretches and potentially soft tissue massage, so that nothing is pulling the knee tight and you have max space for the joint to move.
