This meta-analysis is aimed to analyze the efficacy of bisphosphonates in the management of Perthes disease. A total of 8 animal and 7 human studies have been shortlisted for this analysis. In human studies, common variables for pain, Harris Hip Score (HHS), propensity for femoral head collapse, and total hip arthroplasty (THA), were assessed. In contrast, in animal studies, the data was recorded for epiphyseal quotient, trabecular volume, trabecular separation, trabecular thickness, and trabecular number. Meta-analysis of human studies on ONFH (Osteo-Necrosis of Femoral Head) revealed a statistically significant outcome in HHS [p<0.001; (95% CI: 4.79 – 8.87)], collapse of the femoral head [p=0.079; (95% CI: -0.16 – 0.01)], and THA [p=0.002; (95% CI: -0.19 – -0.04)] whereas the pain score showed an insignificant outcome [p=0.067; (95% CI: -0.62 – 0.04)]. The meta-analysis of selected variables in animal studies revealed a noteworthy outcome in bone volume (p<0.001, 95% Cl), trabecular number (p<0.001, 95% Cl), trabecular thickness (p<0.013, 95% Cl) and trabecular separation (p<0.026, 95% Cl) but not in epiphyseal quotient. Further, analysis of stratified datasets in animal studies revealed a contradictory outcome with significant observations described later in the paper. The use of bisphosphonates holds a promising treatment option in Perthes disease. Although, good quality RCTs are needed to validate it further.
