“…Diagnostic imaging modalities had proven to be very useful in clinical practice to evaluate a wide range of musculoskeletal pathologies (66,67,68,69,70,71,72,73,74,75,76,77). The use of diagnostic imaging techniques such as US, CT and MRI to guide or to verify the effect of musculoskeletal intervention is also widespread (78,79,80,81,82).…”

This review aims to evaluate the role of anaesthetics, steroids and platelet-rich plasma (PRP) employed with ultrasound-guided injection in the management of musculoskeletal pathology of the extremities. Ultrasound-guided injection represents an interesting and minimally invasive solution for the treatment of tendon and joint inflammatory or degenerative diseases. The availability of a variety of new drugs such as hyaluronic acid and PRP provides expansion of the indications and therapeutic possibilities. The clinical results obtained in terms of pain reduction and functional recovery suggest that the use of infiltrative procedures can be a good therapeutic alternative in degenerative and inflammatory joint diseases.

Background Various diagnostic modalities are available to assess the problematic knee arthroplasty. Visualization of soft‐tissue structures in relation to the arthroplasty and bone remains difficult. Recent developments in MRI sequences could make MRI a viable addition to the diagnostic arsenal. Purpose To review the diagnostic properties of MRI, to identify certain causes of complaints that may be directly related to implant failure of total (TKA) or unicompartmental knee arthroplasty (UKA); infection, loosening and wear, instability, malalignment, arthrofibrosis, or patellofemoral problems. Study Type Systematic review. Population Twenty‐three studies were included: 16 TKA, four UKA, and three cadaveric studies. Causes of knee arthroplasty complaints analyzed were; infection (three), loosening and wear (11), malalignment (five) and instability (four). Field Strength and Sequences No field strength or sequence restrictions. Assessment PubMed, SCOPUS, and EMBASE were searched. Risk of bias was assessed using the COnsensus‐based Standards for the selection of health Measurement Instruments (COSMIN) and the QUality Assessment of Diagnostic Accuracy Studies‐2 (QUADAS‐2). Statistical Tests The results of the original research articles are stated. Results Fifteen studies assessed the reproducibility of analyzing infection, loosening and wear, and malalignment. Fourteen of 15 studies were deemed as adequate to good quality. Results showed a moderate to excellent agreement (ICC/K 0.55–0.97). Fourteen studies addressed the accuracy. For infection and loosening and wear the sensitivity and specificity estimates varied between 0.85–0.97 and 0.70–1.00, respectively. The accuracy for malalignment was excellent (r ≥ 0.81). For these studies QUADAS‐2 analysis suggested few risks of bias. A meta‐analysis was not possible due to the heterogeneity of the data. Data Conclusion This study supports that MRI can be used with overall reproducible and accurate results for diagnosing infection, loosening and wear, and malalignment after knee arthroplasty. Nonetheless, studies regarding the diagnosis of instability, arthrofibrosis or patellofemoral complaints using MRI are limited and inconclusive. Level of Evidence: 3 Technical Efficacy: Stage 2 J.

“…Our findings extend those of alignment studies in other patellofemoral pathologies such as patellofemoral pain or instability, and indicate that alignment in PF OA may be similar to that seen in these other populations. 18,19,21,22 In studies of patellofemoral pain or instability, under various conditions in terms of position and loading and across different knee flexion angles, lateral translation, lateral tilt, and proximal translation were greater compared to controls, with larger differences often seen in full extension. 19,20,40,41 Our results were similar, but did not show larger between-group differences in any measure in full extension.…”

Patellofemoral (PF) osteoarthritis (OA) is a prevalent and clinically important knee OA subgroup. Malalignment may be an important risk factor for PF OA. However, little is known about alignment in PF OA, particularly in an upright, weightbearing environment. Using a vertically‐oriented open‐bore MR scanner, we evaluated 3D knee alignment in 15 PF OA cases and 15 individually matched asymptomatic controls. We imaged one knee per participant while they stood two‐legged at four flexion angles (0°, 15°, 30°, 45°), and also while they stood one‐legged at 30° knee flexion. We calculated 3D patellofemoral and tibiofemoral alignment. Using mixed effects models, four of the five patellofemoral measures differed by group. For key measures, PF OA patellae were 6.6° [95%CI 5.0, 8.2] more laterally tilted, 2.4 mm [1.3, 3.5] more laterally translated, and at least 3.7 mm [0.2, 7.2] more proximally translated compared to controls (more with knees flexed). Alignment did not differ between two‐legged stance and one‐legged stance in either group. Statement of Clinical Significance: Our study demonstrated significant and clinically relevant differences in alignment between PF OA cases and controls in upright standing and squatting positions. Our findings were similar to those in previous studies of PF OA using traditional MR scanners in supine positions, supporting the clinical usefulness of existing methods aimed at identifying individuals who may benefit from interventions designed to correct malalignment. © 2019 The Authors.
