Objective: To compare efficacy of PRP v/s hyalonuric acid administration in cases of osteoarthritis of knee. Method: Analysis of two goups of 30 patients each who were administered PRP and Hyalonuric acid respectively. Results: Result was analysed in terms of VAS and WOMAC scores, with PRP showing better results all together. Conclusion: Local administration of PRP gives better long term outcome.

We had evaluated our experience in the treatment of Morrey Modified Masons type III and IV radial head fractures with radial head prosthesis. Materials and Methods: From April 2014 to September 2017, modular radial head prostheses were performed in thirty patients. There were twenty female and ten male with mean age of forty years. The follow-up was a mean of 25 months. Fractures of the radial head have been classified by Morrey Modified Masons classification. The indications for a radial head replacement were type III fractures in 24 cases, type IV fractures in 6 cases, and comminuted radial fracture associated with disruption of the medial collateral ligament in 3 cases. Patients were assessed postoperatively and on follow-up based on Mayo Elbow Performance Index (MEPI) Score. Results: By using the MEPI, out of thirty cases, twenty cases had excellent results, seven cases had good results, two cases had fair results, and one case had poor result. Twenty-eight cases had no complications, one case had infection, and one case had implant failure. Conclusion:Modular radial head prosthesis can be used successfully for treatment of the Morrey Modified Masons type III and IV radial head fractures.
