Hi i have read your question and understood your concerns. Seems that the initial injury has done quite a bit of damage to your leg. The main issues that i can see are: 1. fracture of the right tibia 2. fracture of the left femur 3. dislocation of the right hip 4. dislocation of the knee In the initial part the main objective is to reduce the dislocation and treat the fractures, which was performed as you stated. I will also assess for any nerve or circulation damage which does not seem to be there. However, it will take a few weeks to months for the bone to regain adequate strength to allow for weightbearing. Once bones are healed and you are ambulating without any aid, you will notice that the knee is more loose than usual or compared to the other side. With a history of knee dislocation there is a high likelihood that you have injured at least two or more of the ligaments around the knee. The treatment will basically depend on your level of daily activities and also your symptoms. However, performing the surgery will not be as urgent as the initial surgeries to treat your fractures. You can opt to go for physical therapy and strengthen your muscles which can help in stabilising your knee and reduce your symptoms. Some ligaments do eventually scar down and you will have less symptoms of a loose knee. However, if you are a very active person who does demand a lot from your knee than I do suggest you go ahead with the reconstruction. Earlier stabilisation will lead to earlier rehabilitation and better function.
