Knee Pain Resolved

I am a female age 67 and I have suffered from knee pain and problems such as knee buckling since age 30. I managed it for years by watching my weight, strengthening supporting muscles with targeted exercises, knee braces, use of a cane, pain medication, RICE (rest, ice, compression, elevation) and so on. About twelve years ago I saw a knee specialist who said I had some bone on bone, but not enough for surgery. He recommended RICE (nothing else). Almost two years ago I was having increasing difficulty walking down stairs (up was fine) so I saw another knee specialist who prescribed physical therapy sessions. He said the next step would be either gel or steroid injections. After physical therapy I was better for a while, and I continued the exercises but over time I started to have issues once again. Two months ago I was ready to get some kind of injections and made a follow-up appointment with the doctor. Later that week, but prior to the appointment I was waiting for a prescription at the drug store and began a conversation with another woman who was also waiting. She shared that she had nearly died from sepsis following knee injection. The next day I was working out at the health club and noticed for the first time in my life that when using the leg press my ankles turned inward (over pronation). Later that day I had an appointment for plantar war removal and mentioned my ankles to the podiatrist. He confirmed overpronation, and recommended orthotics, beginning with the over-the-counter kind. A few days later I started using them, and I have had no knee pain or problems since that time. I have no problem going down stairs, I can vary my stride in length and speed, I can do squats with ease. I have had no knee pain whatsoever. I don't know if this will solve things long term, but I'll take the win.
