Review Case ReportsRemoval of a bent intramedullary nail in lower extremity: report of two cases and review of removal techniques.
Removal of a bent intramedullary nail (IMN) is a rare but challenging orthopedic problem. Several removal techniques have been described up to date; however, there is no extensive review and no algorithm to manage these cases in current literature. The purpose of this paper is to present two cases that presented with bent IMN and provide an algorithm for management of this rare complication.

Early clinical and radiological results of total knee arthroplasty using patient-specific guides in obese patients.
Total knee arthroplasty (TKA) is a challenging procedure in patients with a high body mass index (BMI). The aim of our study was to assess the outcome and accuracy of restoration of mechanical alignment in TKA using patient-specific guides (PSG) involving patients with high BMI. ⋯ Patient-specific guides technology restores the coronal mechanical axis reliably in obese patients without adversely affecting outcomes. Our short-term follow-up has shown favorable outcomes. Surgeons should use these customized jigs as a guide and adjust the size of components, alignment and rotation according to normal surgical principles.

MRI-associated classification to evaluate the outcome after autologous reconstruction of the medial patellofemoral ligament: a preliminary study.
Purpose of this study was to establish and validate an MRI-associated classification to graduate postoperative results of MPFL reconstructions. ⋯ We were able to establish and validate an MRI-associated classification to graduate the postoperative outcome after MPFL reconstructions. Foresighted, the presented classification might support further decision making in case of unsatisfying postoperative results.

Prospective clinical and radiostereometric analysis of the Fitmore short-stem total hip arthroplasty.
Uncemented short, curved femoral stems may help save proximal bone stock during total hip arthroplasty (THA) and facilitate insertion in minimal invasive surgery. The aim of this 2 year, prospective, single-center study was to examine the stability and migration of the Fitmore (®) stem in THA using model-based radiostereometric analysis (RSA), and thus predict the implant's long-term survival. In addition, we evaluated the stem's clinical performance using standard clinical measures. ⋯ We conclude that the Fitmore Hip Stem stabilizes after 3 months and achieves good short-term clinical results in most cases.

Meniscal degeneration in human knee osteoarthritis: in situ hybridization and immunohistochemistry study.
Meniscus injury is one of the causes of secondary osteoarthritis (OA). However, the role of meniscus is still unclear. Human meniscal distribution of cells and cartilage oligomeric matrix protein (COMP) and their changes in advanced OA were analyzed. ⋯ Our results show a decreased cell population, with low COMP and altered matrix organization in osteoarthritis menisci that suggest an altered meniscal scaffold and potential impairment of meniscal function. These meniscal changes may be associated with the development of knee osteoarthritis.
