“…To our knowledge, there is only one surgical clinical trial specifically in a PF OA population, with this study evaluating the effectiveness of patellar resurfacing compared with patellar retention in a PF OA population with KL grade 4 [100] . Despite the different methods of surgery, postoperative radiological assessment outcomes (patellar tilt, mechanical femorotibial angles and congruence angle) between the two groups were almost identical.…”

We recommend to develop clear clinical criteria for PF OA and to reach consensus on the definition of PF OA by both radiographs and MRI. Additionally, more understanding is necessary to be able to distinguish PF symptoms from those arising from the tibiofemoral joint. More insight is needed on effective treatment strategies for PF OA; specifically, tailoring nonpharmacological treatments to individuals with PF OA, and determining whether isolated PF OA requires different treatment strategies than combined PF and tibiofemoral OA.

Upregulation of microRNA‑590 in rheumatoid arthritis promotes apoptosis of bone cells through transforming growth factor‑β1/phosphoinositide 3‑kinase/Akt signaling

The aim of the present study was to further define the role of microRNA (miR)-590 in osteoarthritis (OA) and to investigate the underlying mechanism. In brief, reverse transcription-quantitative polymerase chain reaction was used to analyze miR-590 expression in bone tissue samples from rats with OA. Results indicated the expression of miR-590 was increased. miR-590 upregulation induced apoptosis in bone cells, whereas miR-590 downregulation reduced apoptosis of bone cells. Furthermore, miR-590 upregulation suppressed the protein expression levels of transforming growth factor (TGF)-β1, phosphoinositide 3-kinase (PI3K) and phosphorylated (p)-Akt in bone cells. However, downregulation of miR-590 induced the protein expression levels of TGF-β1, PI3K and p-Akt in bone cells. In addition, TGF-β1 attenuated the effects of miR-590 upregulation on bone cell apoptosis and the inactivation of PI3K inhibited the effects of miR-590 downregulation on bone cell apoptosis. Taken together, the present data suggested that miR-590 promoted apoptosis in bone cells from rats with OA by regulating the TGF-β1/PI3K signaling pathway.

“… 41 Miller et al reported that following an increase of the ACO between 2 and 4 mm, the flexion decreases by 1.8° and 4.4°, respectively. 42 Patellar height (can be measured using different techniques): 43 Insall-Salvati Index (ISI) ( Figure 3C ): it is the ratio between the patellar tendon length (measured from its origin at the patellar lower pole to its insertion in the tibial tuberosity, line B) and the length of the patella (measured as the longest diagonal line across the patella, line A). Normally, the ratio is about 1.02, with a variation of less than 20%.…”

Although total knee arthroplasty (TKA) is considered one of the most successful procedures, however, a subset of patients are unsatisfied with the results, even with the introduction of new technologies and implant designs. Radiological assessment of TKA is still considered the most prevalent imaging modality for evaluating the knee joint pre-and postoperatively. Assessment of various angles and indices which could be measured in different radiographic views of the knee provides valuable information about the alignment of the entire limb and the individual prosthetic components, more so in the light of recent nuanced concepts of technique, alignment, and balance. This review article aims to present a comprehensive yet systematic approach to the most useful radiographic parameters for assessing the knee preoperatively and post-TKA by explaining the tools and techniques used for measuring various angles, indices and ratios in the coronal, sagittal and axial planes for diagnosis, preoperative planning, postoperative assessment, and routine follow-up. The protocol we followed in this review entailed first reporting the possible applications and software which could help in measuring these variables, then we mentioned the required series of knee radiographs. For the desired variables, we divided the assessment according to each plane, and in each, we reported the optimum position of the desired radiographic view followed by determining the axis and lines which will later form the desired angles to be measured; finally, we collected all the measurements in a table with the native knee values and the most accepted values after TKA.
