“…Type IV patella was not detected in female. In the study conducted by Demir et al 20 on one hundred and twenty-five patients with 3-4 degree chondromalacia patellae and an average age of 48.8±8.7, they stated that 62.4% of the patients were women and 55.2% were on the right side. Additionally, they did not find any significance between genders between those with and without chondramalacia.…”

Aims: The present study was conducted to determine patella types, chondromalacia patella finding in the Turkish society, and to evaluate the differences between gender and age groups to with Magnetic Resonance Imaging (MRI). Methods: The study had a retrospective design, and included 256 people (122 females, 134 male) who were between the ages of 18 and 81 admitting to the Orthopedic Clinic of Kozan State Hospital with various complaints in knee joints and different preliminary diagnoses between January 2015 and December 2017. The evaluations made on MR images in the study. We evaluated in our study were patella types, chondromalacia classification and comparison according to age and gender. Results: Patella types did not differ between the genders at significant levels; however, significant differences were detected between the genders in the chondromalacia patella (p=0.03). Patella types were classified, and it was found that Type II Patella was the most common patella type, and Type IV was identified as the least common. Conclusion: We believe that the data obtained in our study will be useful in understanding morphometry of patella in anatomy, radiology and orthopedics fields. Based on our ﬁndings, we concluded that the anatomical shape of the patella is an important anatomic parameter, which may reﬂect the development of defects in the patellofemoral region It is also clinically important in terms of identifying knee pathologies more clearly in the aging process, and revealing the differences between societies, and in many pathologies that involve patella.

“…In order to proportionally reveal the morphological differences occurring in the patellofemoral joint, ratios such as pML/SA, SD/LCL, MFC-LFC/LFL, mFL/LFL and ID/LCL were also calculated. [23][24][25] The study employed two distinct analytical approaches to examine the relationship between arthropathy severity and measured variables.…”

IntroductionKnees affected by haemophilic arthropathy exhibit distinct differences in both bone morphology and soft tissue behaviour. This study aims to analyse the morphological characteristics of the distal femur and patellofemoral joint in patients with haemophilia in comparison to normal healthy population.Material and MethodsStudy was conducted as pair‐matched case‐control study with 43 individuals in both the haemophilia group and the control group. Patellar luxation, patellar tilt (PT), length of the patella in both axis (pAP, pML), depth and angle of trochlear sulcus (SD, SA), lateral trochlear inclination (LTI), medial and lateral femoral facet length (mFL, LFL), intercondylar depth (ID), transepicondylar axis (TEA) and lateral condyle length (LCL) were assessed on knee MRI. Correlation between Pettersson score and measured variables were also analysed.ResultsPT was medial sided in 10 (23.2%) cases in haemophilic group. Mean values of pAP, pML, PT were significantly lower in haemophilia group (p < .001, p: .007, p = .001 respectively). There were no significant changes in SA (p = .628), SD (p = .340), LTI (p = .685), LFL (p = .241) and MFC‐LFC (p = .770) whilst mFL was significantly longer in haemophilia group (p = .009). ID (p < .001), TEA (p = .007) and LCL (p = .001) were all shorter in haemophilia group. Pettersson score was inversely correlated with pAP, pML, ID, TEA, LCL, pML/SA and ID/LCL.ConclusionMorphological changes in haemophilic arthropathy involve a smaller and medially‐tilted patella, narrowed lateral condyle and transepicondylar axis, combined with reduced intercondylar depth. These alterations must keep in mind especially in pre‐ and intraoperative assessments for arthroplasty procedures.

Background Lateral patellofemoral compression syndrome (LPCS) is a condition characterized by increased lateral patellofemoral joint pressure caused by long-standing lateral patella tilt, adaptive lateral retinaculum tightening, and an imbalance in stress between the lateral and medial femoral condyles. Diagnosis of LPCS is challenging because of its complex and diverse etiology and pain mechanisms, thus we lack objective diagnostic criteria. Purpose This study aimed to explore the feasibility of various structural measurement parameters of MRI of the knee to diagnose LPCS and to identify new MRI diagnostic indicators to as references and guidance for LPCS clinical diagnosis. Methods This study enrolled 168 patients, who were divided into three groups: The LPCS group, the simple osteoarthritis (SO) group, and the normal control group (n = 56 participants per group). Diagnosis of all patients was carried out at the Department of Sports Medicine, Peking University Third Hospital. A standardized MR scanning protocol was used, including sagittal and coronal fat-suppressed proton density-weighted imaging and sagittal T1-weighted imaging. Two radiologists used the picture archiving and communication system to analyze the MR images and measure the patellarpatellar tibial angle (P-PTA), the quadriceps-patellar angle (Q-PA), the patellar length (LP), the patellar tendon length (LT), the LP/LT ratio, and the Insall-Salvati ratio (ISR). Results The LPCS group had significantly lower P-PTA and LP values, but higher LT and ISR values, compared with those in the normal and SO groups (all P < 0.05). Compared with that in the normal group, the LPCS groups' Q-PA value was higher (P = 0.034). According to receiver operating characteristic analysis, the optimal cut-off values for PPTA, LP, LP/LT, and ISR were 146.45°, 41.10mm, 0.85, and 1.19, with sensitivities and specificities of 67.86%/59.82%, 78.57%/55.36%, 67.86%/58.93%, and 66.07%/60.71%, respectively. Conclusion Measurement parameters of MRI, particularly P-PTA and ISR, can serve as important tools to assist in the diagnosis of LPCS. Assessment of these parameters should be included in the clinical diagnostic process for LPCS to improve diagnostic accuracy.
