Leg wound not healing. Completely?

Hi Doc, Following with my previous post. Is it advisable to apply Betadin and keep it open? Since I applied turmeric powder it has accumualted on top of the wound, I didnt try to clean since it may pull off healed portion. Please suggest Prev Post I got injured in leg as bike skidded off and my leg hit footpath. This was 1.5 months back. Area of wound was large. Now the wound has healed 90%. A wound just as finger tip is still raw. I see that watery liquid (Not yellowish) is getting generated daily and hence delaying healing (Yellow circle in picture). Though it dries off again this liquid gets generated and the dried surface becomes watery. I consulted Dr. Prashanth BN in Vijayshree hospital. I have been dressing regularly and pain has reduced quite a bit. I used Augmentin D as antibiotic and betadin as ointment before dressing. I also used turmeric powder as its ayruvedic. What should I do now to get the wound healed completely?
