Linde KN, et al. - In this prospective cohort study, researchers ascertained if bone quality and other preoperative predictive factors can affect implant migration and the survival of knee arthroplasty. They examined preoperative predictors of postoperative tibial component migration in cemented and cementless total knee arthroplasties or cemented unicompartmental knee arthroplasty. Study participants included 100 consecutive patients (65 women) at a mean age of 67.7 years (range 39-87 years). In terms of systemic BMD, bone turnover markers, and OA grade in the knee, migration of tibial components inserted with or without bone cement was not impacted by the preoperative bone quality.
