Jean, I decided to read all of your posts before answering you. For one thing "normal" is different for everyone. Some people have a faster recovery and some a slower recovery. However, I feel your doctor has misled you.
Most of all I see that you played pickleball several times at 2 weeks. At that point your flexion was 115. That is the source of your current problem.
When you have surgeries, your muscles are disrupted and they do not work as well after surgery as they did before. My quad took two full weeks to recover from surgery. During those two weeks, I spent 80% of my time in bed or on the couch with my leg elevated so that the swelling would go down.
When you muscles are weak, they do not fully support your leg and the joint itself has to support the leg. You had a new joint, with soft tissue swelling and weak muscles when you played pickleball. So, no wonder your joint is still complaining. You simply cannot rush the healing after this major surgery. Your over activity has made your soft tissues angry and they are yelling at you to stop.
I cannot believe that your husband is trying to tempt you to play with a swollen, inflamed knee. If you want the fun, you can go there and talk to people, but keep your leg up on a chair. It is a bad idea to even think of playing right now. So, I suggest that you spend some time with your leg elevated and buy time. I mean hours, as many as you can so that the swelling and inflammation leave your leg. 4 hours in the am and four to five hours in the pm.
I used a stationery bike myself, but two days after surgery, i hopped onto it and My Pt said---what are you doing??? He let me ride for 5 min. Here was his formula: ride for 5 min. swelling? ride for 3 min. no swelling, ride for 7 min. As you can see, first, you have to bring down the swelling, then you have to GRADUALLY get back to your activities. I am a ski instructor, but I did not ski until 4 months post surgery. I skied better since I no longer had a wonky knee. But you will have to trade the next three months for your future sports life. There is no way at all that you are ready to run, stop, start, run.
If you stress the joint too much now, you risk tendonitis, which is no fun at all. So, major surgery, one year to full recovery, you will get back to playing sports, but you will have to move slower to get there. I am going to give you some articles from the library to read.
