Introduction: Avascular necrosis (AVN), most commonly affects femoral head. Etiology may be traumatic or non-traumatic. The goal of treatment is preservation of head of femur in early stages I and II by different hip preserving methods & to delay hip arthroplasty. Aims and Objectives: To evaluate and discuss the results of iliac crest cancellous bone graft enhanced with platelet rich plasma and core decompression in of AVN head of femur grade I and II. Method and Materials: This study was done in Deptt of Ortho., RNT MC & Hospital, Udaipur from 1 Oct. 2016 to 30 Sep. 2018. 25 Patients (38 hips) of both sex and aged between 25 to 50 years with AVN head of femur grade I and II were treated by core decompression with platelet rich plasma enhanced cancellous bone graft. Final results were graded according to Harris hip score. Results: Final Results were 10 hips (26.3%) had excellent, 17 hips (44.7%) good, 7 hips (18.4%) had fair and 4 hips (10.5%) had poor result. There was improvement in mean Harris Hip Scores by 10.1 points (73.1 to 83.2). Conclusion: Pain relief was achieved and probably due to decompression, and curettage of necrotic area. Improvement in Harris hip score and delay the need for THR.
