- Revision DL: revision arthroplasty via the direct lateral approach; Revision posterior: revision arthroplasty via the posterior approach; Primary THA (OA): primary total hip arthroplasty due to osteoarthritis; Primary THA (fracture): primary total hip arthroplasty due to femoral neck fracture. N, number of fibrils in areas showing transversely sectioned collagen fibrils; significant p value in bold. Pair-wise comparison showed statistical significance of p < 0.001 except for primary THA vs fracture (p = 0.43)
