“…Specific cartilage sequences, such as dGEMRIC (delayed gadolinium-enhanced MRI of cartilage) and T2 mapping, may have a role in the diagnosis and management of patellofemoral cartilage injuries in the future, 49 - 51 as may newer technologies, such as delayed quantitative CT arthrography (dQCTA) 52 and SPECT/CT (single photon emission computed tomography with conventional computed tomography). 53 , 54 …”

Objective:Patellofemoral instability is common and affects a predominantly young age group. Chondral injury occurs in up to 95%, and includes osteochondral fractures and loose bodies acutely and secondary degenerative changes in recurrent cases. Biomechanical abnormalities, such as trochlear dysplasia, patella alta, and increased tibial tuberosity-trochlear groove distance, predispose to both recurrent dislocations and patellofemoral arthrosis.Design:In this article, we review the mechanisms of chondral injury in patellofemoral instability, diagnostic modalities, the distribution of lesions seen in acute and episodic dislocation, and treatments for articular cartilage lesions of the patellofemoral joint.Results:Little specific evidence exists for cartilage treatments in patellofemoral instability. In general, the results of reparative and restorative procedures in the patellofemoral joint are inferior to those observed in other compartments of the knee.Conclusion:Given the increased severity of chondral lesions and progression to osteoarthritis seen with recurrent dislocations, careful consideration should be given to early stabilisation in patients with predisposing factors.

“…By a combination of 3-D analysis of component position, mechanical and anatomical axes as well as the pattern of distribution and intensity of bone tracer uptake SPECT/CT offers a richer source of diagnostic data to the radiology, the nuclear medicine and finally the orthopaedic fraternity [2,3,[5][6][7][8][9]. Hence, SPECT/CT is considered as one important diagnostic part of their routine algorithm in patients with pain, stiffness, swelling or instability after TKA.…”

“…A more profound insight into the relationship of TKA component design and position, alignment and physiological remodelling within the bone-prosthesis interface could help to establish new diagnostic algorithms and a significant improvement of specificity and sensitivity of SPECT/ CT in patients after TKA [2,3,[5][6][7][8][9].…”

Zusammenfassung Seit Einf?hrung in die klinische Routine in den 70er Jahren stellt die Skelettszintigrafie eines der h?ufigsten nuklearmediznischen Untersuchungsverfahren dar. Ihre Sensitivit?t bei der Detektion skelettaler L?sionen ist sehr hoch, Spezifit?t als auch r?umliche Aufl?sung sind hingegen limitiert. Dies gilt auch, wenn die Skelettszintigrafie durch eine Einzelphotonenemissionscomputertomografie (SPECT) erg?nzt wird. Hybridkameras, welche die Akquisition eines SPECT und einer R?ntgencomputertomografie (CT) in einem Untersuchungsgang erlauben, stehen seit ca. 10 Jahren kommerziell zur Verf?gung. Die SPECT/CT verbessert die Genauigkeit der Knochenszintigrafie beim Staging von Tumorerkrankungen erheblich. Auch bei der Diagnostik gutartiger Ver?nderungen des Skeletts ergeben sich gegen?ber der konventionellen nuklearmedizinischen Bildgebung deutliche Vorteile der Hybriddiagnostik. Die M?glichkeit der Quantifizierung des regionalen Traceruptakes in absoluten Einheiten und sog. multimodale Rekonstruktionstechniken stellen j?ngste methodische Fortschritte dar.
