Effects of PRP injection combined with intersecting femoral head decompression versus combined with multiple core decompression in the treatment of avascular necrosis of femoral head—a single-center retrospective cohort study

Unlike conventional core decompression, PRP can penetrate slowly into the cancellous bone of the femoral head through drilled pores in patients treated by intersecting femoral head decompression, thus extending duration of action of PRP. Compared with PRP injection combined with MCD, PRP injection combined with intersecting femoral head decompression had better functional and radiographic outcomes in our study.
