Femoral condyle insufficiency fractures: associated clinical and morphological findings and impact on outcome

“…In particular, meniscal tears appear to be frequently encountered with these lesions, although existing studies are limited by small numbers and low-fieldstrength magnetic resonance (MR) imaging systems [7]. Though treatment options vary widely and include oral/ intravenous bisphosphonate treatment, high tibial osteotomy, unicompartmental knee arthroplasty, and total knee arthroplasty (TKA), no studies to date have explored the ways in which MR findings of FCIF lesions can be used to predict the longitudinal evolution of these lesions and how they are associated with treatment [11][12][13][14][15][16]. Our objectives were therefore to (i) analyze MR characteristics of FCIF, (ii) describe associated cartilage, bone marrow, and ligamentous abnormalities, and (iii) correlate these findings with concomitant clinical symptoms, risk factors, and longitudinal outcomes.…”

Defining the role of bisphosphonates for osteonecrosis of the knee: a systematic review

“…50--57 A flow diagram of studies is presented in Figure 1. One randomized controlled trial was included 51 as well as five case series, 50,52,53,56,57 and two case reports. 54,55 The overall population comprised 89 patients, and concise details of the clinical studies are given in Table 2.…”

Gait Assessment of Patients with Spontaneous Osteonecrosis of the Knee: A Retrospective Case Controlled Study

“…Outcome measures to assess the effect of treatment often include repeated MRI and use of self-reported pain levels [8,32]. These assessment tools have some limitations: MRI is an expensive test that requires a relative long waiting time, and self-reported pain assessment is a subjective one that should be supported with objective tools.…”
