“…The authors found that a hot patella was significantly correlated with anterior knee pain [22]. A normal bone scan following TKA surgery is reassuring and suggests that a patellofemoral problem is unlikely [22].…”

“…Patellofemoral problems such as progression of OA, instability and maltracking are considered to be one of the most frequent causes for revision after TKA without primary patellar resurfacing [15,16]. Approximately one third of patients revised in the first 5 years after TKA are attributed to instability or patellofemoral complications [15].…”

BackgroundThe purpose of our study was to evaluate the clinical value of hybrid SPECT/CT for the assessment of patients with painful total knee arthroplasty (TKA).MethodsTwenty-three painful knees in patients following primary TKA were assessed using Tc-99m-HDP-SPECT/CT. Rotational, sagittal and coronal position of the TKA was assessed on 3D-CT reconstructions. The level of the SPECT-tracer uptake (0-10) and its anatomical distribution was mapped using a validated localization scheme. Univariate analysis (Wilcoxon-Mann-Whitney, Spearmean`s-rho test, p < 0.05) was performed to identify any correlations between component position, tracer uptake and diagnosis.ResultsSPECT/CT imaging changed the suspected diagnosis and the proposed treatment in 19/23 (83%) knees. Progression of patellofemoral OA (n = 11), loosening of the tibial (n = 3) and loosening of the femoral component (n = 2) were identified as the leading causes of pain after TKA.Patients with externally rotated tibial trays showed higher tracer uptake in the medial patellar facet (p = 0.049) and in the femur (p = 0.051). Patients with knee pain due to patellofemoral OA showed significantly higher tracer uptake in the patella than others (p < 0.001).ConclusionsSPECT/CT was very helpful in establishing the diagnosis and guiding subsequent management in patients with painful knees after TKA, particularly in patients with patellofemoral problems and malpositioned or loose TKA.

“…Die Autoren kamen zu dem Ergebnis, dass die SPECT/CT insbesondere bei Verdacht auf patellofemorale Probleme und bei Lockerung oder schlecht positionierter tibialer Komponente sehr hilfreich ist. Auch bei der Abklärung postoperativer Probleme der Patella hat die SPECT/CT ein großes Potenzial [1]. Erste Studien mit noch kleinen Fallzahlen deuten auch bei der Frage nach Infekten von Kniegelenkprothesen auf einen Nutzen der Entzündungs-SPECT/CT im Vergleich zur herkömmli-chen planaren Szintigraphie hin [13,23].…”
