“…increased lateral patellar tilt, and accentuated tibial tubercle offset [3,5,6,9,13,23]. Although radiographs are still valid for initially evaluating OPI, in many practices computed tomography (CT) scans and, in particular, magnetic resonance (MR) imaging are increasingly used [4,11,31].…”

To evaluate and compare the diagnostic utility of multiple quantitative parameters as measured on knee magnetic resonance (MR) examinations of patients suffering objective patellar instability (OPI). We performed a retrospective evaluation of knee MR examinations in a group of 46 patients (59 knees) with clinically proven OPI, and in a control group of 69 patients (71 knees). Multiple quantitative parameters in both groups were statistically evaluated and compared for their association with OPI. OPI patients tend to present shallower trochlear groove (<5 mm), larger Insall-Salvati index (>1.2), shorter patellar nose (<9 mm), smaller morphology ratio (<1.2), and larger patellar tilt (>11 degrees ) than control patients. The best sensitivities were those of the lateral patellar tilt (92.7%), the trochlear groove depth at the roman arch level (85.7%) and the Insall-Salvati index (78%). The best specificities were those of the morphology ratio (86.9%), the patellar nose (84.5%) and the patellar tendon length (84.5%). Shallow trochlear groove may be confidently identified at the roman arch view in OPI patients. Patella alta may be more reliably detected by the Insall-Salvati index in OPI patients. Patellar nose and morphology ratio are very specific indicators of OPI. A short patellar nose (that is to say, a patellar nose ratio of <0.25) has a high association with OPI. Lateral patellar tilt remains the single feature with the highest sensitivity and specificity for identifying OPI patients.

“…In the presence of a cartilaginous lesion of the medial patella, release may increase the load in this area, resulting in worsening of the lesion. Also, if the patient has an increased Q angle, isolated release can increase this angle, thus increasing instability symptoms [98][99][100][101][102][103][104][105] .…”

SummaryPrimary traumatic patellar dislocation is common, particularly in young active individuals. A consensus on its management is still lacking. The present work provides easily accessible guidelines to be considered as recommendations for a good clinical practice developed through a process of systematic review of the literature and expert opinion, to improve the quality of care and rationalize the use of resources. Level of evidence: Ia.

ÖZETPatellofemoral ağrı sendromu (PFAS) ön diz ağrısının genellikle genç bayanları etkileyen sık bir nedenidir. Patellofemoral ağrı, tüm kas-iskelet sistemi yakınmalarının yaklaşık %9-10'unu, tüm diz problemlerinin ise %20-40'ını oluşturan en yaygın kas-iskelet tanılarından biridir. Geçmişte sadece patellofemoral dizilim bozukluğu kaynaklı olduğuna inanılan patellofemoral ağrı günümüzde kompleks ve multifaktöriyel bir problem olarak ele alınmaktadır. Patellofemoral eklem ağrısı olan hastaların değerlendirilmesinde anamnez, klinik ve radyolojik bulgular bir arada değerlendirilmelidir. PFAS tanısında halen bir netlik olmamakla beraber, dokulara direnç göstereceği yükün üzerinde yüklenmelerin doku homeostazını bozması ve bunun sonucunda da ağrının oluşumunu öne süren doku homeostazisi teorisi popülerlik kazanmaktadır. Bu direncin miktarı ise kişinin özelliklerine göre (obezite, cinsiyet, spor, genetik vb) değişebilir.Anahtar Kelimeler: Patellofemoral ağrı sendromu, diz önü ağrısı, Q açısı, dinamik valgus SUMMARYPatellofemoral pain syndrome (PFPS) is a common cause of anterior knee pain, usually affecting young women. Patellofemoral pain is one of the most common musculoskeletal diagnoses, corresponding to approximately %9-10 of all of the musculoskeletal complaints, and 20 to 40% of all knee problems. Patellofemoral pain, which was in the past believed to be originating only from patellofemoral malalignment, is nowadays considered as a complex and multifactorial problem. In the assessment of patients with patellofemoral joint pain patient history, clinical and radiological findings should be evaluated together. Although there is still not a clear evidence on diagnosis of PFP; the tissue homeostasis theory, suggesting that excessive loads on tissues over their resistance results in pain, is gaining popularity. The amount of this resistance can vary according to the patient's properties like obesity, gender, sports, genetics.
