Purpose
Due to age and gender, patients awaiting total knee or hip arthroplasty (TKA/THA) are at a higher risk of osteoporosis. In joint arthroplasty, low bone mineral density (BMD) is a risk factor for implant osseointegration, durability, and prosthesis complications. This study aims to investigate the prevalence and treatment rate of osteoporosis in patients undergoing total joint arthroplasty (TJA).
Methods
We applied a comprehensive literature search through PubMed, Cochrane Library, and EMBASE from inception to July 10, 2021, for studies investigating the prevalence and treatment rate of osteoporosis in TJA patients. The aggregated prevalence was calculated with the random-effects model, and the heterogeneity between studies was checked by Cochran’s Q test and quantified by the I2 statistic. We performed subgroup analyses and meta-regression analyses to determine the source of heterogeneity. Publication bias was assessed by a funnel plot and verified by Egger’s test. Anti-osteoporosis treatment for TJA patients was described qualitatively and quantitatively.
Results
Of 4561 citations identified by the search strategy, 11 studies including 3462 patients were eligible for inclusion. The pooled prevalence of osteoporosis and osteopenia in TJA patients was 24.8% (95%CI: 14.1–37.2%) and 38.5% (95%CI: 29.3–48.0%), respectively. The prevalence of osteoporosis/osteopenia in TJA patients was 64.0% (95%CI: 45.8–80.3%). In terms of gender, the pooled prevalence of osteoporosis in males, females, and postmenopausal females were 5.5% (95%CI: 1.5–11.4%), 29.0% (95%CI: 18.3–41.1%), and 38.3% (95%CI: 13.2–67.1%), respectively. The treatment rate of osteoporosis in TJA patients was 32.9% (95%CI: 15.2–53.1%) by a random-effects model.
Conclusions
Osteoporosis is highly prevalent in patients undergoing TJA, especially in postmenopausal females. However, the treatment rate of osteoporosis is low. Considering the possibility of surgical complications, clinicians should strengthen their awareness of pre-operative BMD assessment and manage osteoporosis in high-risk patients.
