TLDR
The intensity of SPECT/CT tracer uptake in the medial and lateral knee compartment significantly correlated with varus or valgus alignment of the knee, which is related to the degree of osteoarthritis.About:

Journal ArticleDOI

TL;DR: For the majority of applications, SPECT/CT should be a routine imaging technique, fully integrated into the clinical decision-making process, including oncology, endocrinology, orthopaedics, paediatrics, and cardiology.
Journal ArticleDOI
Maximum standardised uptake value of quantitative bone SPECT/CT in patients with medial compartment osteoarthritis of the knee
TL;DR: The SUVmax of quantitative bone SPECT/CT was highly correlated with traditional imaging parameters for medial compartment OA severity of the knee and is a promising imaging technique for the objective assessment of knee OA.
Journal ArticleDOI
Clinical value of SPECT/CT in the painful total knee arthroplasty (TKA): a prospective study in a consecutive series of 100 TKA.
TL;DR: The diagnostic benefits of SPECT/CT in patients after TKA have been proven and typical pathology-related BTU patterns were identified, which will improve reporting quality.

Medial malleolar osteotomy for the treatment of talar osteochondral lesions: anatomical and morbidity considerations
André Leumann,André Leumann,Monika Horisberger,Olaf Buettner,Magdalena Mueller-Gerbl,Victor Valderrabano +5 more
TL;DR: Anatomically, there is an optimal location for the medial malleolar osteotomy at the medial ankle edge involving minimal cartilage damage, and clinical results showed no short- or mid- term morbidity and little long-term morbidity.

Effect of high tibial osteotomy on joint loading in symptomatic patients with varus aligned knees: a study using SPECT/CT
Armin Mucha,Milos Dordevic,Anna Hirschmann,Helmut Rasch,Felix Amsler,Markus P. Arnold,Michael T. Hirschmann +6 more
TL;DR: In patients with medial compartment, overloading due to varus malalignment HTO led to a significant decrease in BTU in the medial joint compartments, and SPECT/CT could be used for assessment of adequate correction and healing after HTO.

Journal ArticleDOI
The Role of Knee Alignment in Disease Progression and Functional Decline in Knee Osteoarthritis
TL;DR: This is the first demonstration that in primary knee OA varus alignment increases risk of medial OA progression, that valgus alignment increased risk of lateral OA progress, that burden of malalignment predicts decline in physical function, and that these effects can be detected after as little as 18 months of observation.
Journal ArticleDOI
Radiographic analysis of the axial alignment of the lower extremity.
TL;DR: The axial alignment of the lower extremities of twenty-five normal male volunteers whose mean age was thirty years was studied using a standardized radiograph of the entire lower extremity and the anatomical axis of the femur did not pass through the center of the knee.
Journal ArticleDOI
The effect of high tibial osteotomy on osteoarthritis of the knee. An arthroscopic study of 54 knee joints.
TL;DR: Arthroscopic findings in repair of articular surfaces and the operation's effect on healthy components made it clear that the ideal correction method is to align the mechanical axis to pass through a point 30 to 40 per cent lateral to the midpoint.
Journal ArticleDOI
The distribution of load across the knee. A comparison of static and dynamic measurements
F Johnson,S Leitl,W Waugh +2 more
TL;DR: A comparison of the results from the two methods led to the conclusion that both calculations are required for the successful outcome of a tibial osteotomy or a total arthroplasty.

Varus and valgus alignment and incident and progressive knee osteoarthritis
Leena Sharma,Jing Song,Dorothy D. Dunlop,David T. Felson,Cora E. Lewis,Neil A. Segal,James C. Torner,T. Derek V. Cooke,Jean Hietpas,John A. Lynch,Michael C. Nevitt +10 more
TL;DR: In knees with osteoarthritis, varus and valgus alignment each increased the risk of progression in the biomechanically stressed compartment, and Varus but not valGus alignment increased therisk of incident tibiofemoral osteOarthritis.
