“…This is in line with results found by Kang et al showing an increase in MRI abnormalities with changes in sulcus geometry. Since kinematics can be changed with noninvasive treatments like bracing and training, one could potentially delay or prevent the onset of PFOA in young people with malalignment in the PFJ. Further prospective studies are needed to investigate the exact relation between malalignment and early OA in young populations.…”

Background Patellofemoral pain (PFP) patients show increased prevalence of patellar malalignment. Structural and alignment abnormalities of the patellofemoral joint (PFJ) may play a role in development of PFP and patellofemoral osteoarthritis (PFOA). Objectives Evaluating associations of patellofemoral alignment and femoral geometry with bony and cartilaginous abnormalities in PFP patients and healthy control subjects. Methods Data from a case‐control study were used (64 PFP subjects, 70 control subjects, 57% female, age 23.2 (6.4)). Alignment and femoral geometry measures in the PFJ were determined using MRI. Structural abnormalities in the PFJ associated with OA (bone marrow lesions, osteophytes, minor cartilage defects and Hoffa‐synovitis), quantified cartilage composition (T1ρ relaxation times) in the PFJ and perfusion within the patellar bone were examined using different MRI techniques. Associations were analyzed using regression analyses, adjusted for potential confounders. Results Lateral patellar tilt was negatively associated with presence of osteophytes on both patella (OR 0.91; 95% CI 0.84 to 0.98), anterior femur (OR 0.92; 95% CI 0.84 to 0.99) and minor cartilage defects on patella (OR 0.91; 95% CI 0.84 to 0.99). Patella alta was positively associated with the presence of bone marrow lesions in the patella and minor cartilage defects (OR 48.33; 95% CI 4.27 to 547.30 and OR 17.51; 95% CI 1.17 to 262.57, respectively). Patella alta and medial patellar translation were positively associated with T1ρ relaxation times within trochlear cartilage (β 5.2; 95% CI 0.77 to 9.58, and 0.36; 95% CI 0.08 to 0.64, respectively). None of the alignment and geometry measures were associated with bone perfusion. Conclusion Our study implies that associations between patellofemoral alignment and geometry and structural joint abnormalities linked to OA are already present in both PFP patients and healthy control subjects.

“…The brace resulted in modest but significant pain relief, as well as the shrinking of PF bone marrow lesions. Since then, data have shown that in persons with PF OA this patellar brace alters patellar position and increases contact area between the patella and femoral trochlea [99]. But it is unclear whether benefits observed with bracing are due to non-specific (placebo) effects, re-alignment and/or compression of the patella.…”

We recommend to develop clear clinical criteria for PF OA and to reach consensus on the definition of PF OA by both radiographs and MRI. Additionally, more understanding is necessary to be able to distinguish PF symptoms from those arising from the tibiofemoral joint. More insight is needed on effective treatment strategies for PF OA; specifically, tailoring nonpharmacological treatments to individuals with PF OA, and determining whether isolated PF OA requires different treatment strategies than combined PF and tibiofemoral OA.

“…According to the method of Christopher et al (22)and Callaghan et al (23), a line that passes through the deepest portion of the trochlear groove perpendicular to the posterior condylar reference line was drawn. The intersection of this line and the maximal patella width line was de ned as point O.…”

Purpose To investigate the morphological parameters of the vastus medialis obliquus (VMO) muscle and delineate its importance in the maintenance of patellofemoral joint stability.Methods The magnetic resonance imaging (MRI) data of 75 knees (54 patients) with recurrent lateral patella dislocation (LPD) and 75 knees (70 patients with similar age, gender and body mass index) were retrospectively analyzed. Five morphological parameters related to VMO (elevation on sagittal plane and coronal plane, cross-sectional area ratio, craniocaudal extent, muscle-fiber angulation,) and two parameters of patella tilt (patella tilt angle, bisect offset ratio) were measured in MRI images, and the types of trochlear in each patient were recorded. Finally, the differences of these parameters between the two groups were analyzed.Results Compared with the control group, the patients with recurrent LPD showed significantly higher in sagittal VMO elevation (10.4 ± 2.3 mm vs 4.1 ± 1.9 mm), coronal VMO elevation (15.9 ± 5.7 mm vs 3.9 ± 3.7 mm), muscle-fiber angulation (35.4 ± 8.0° vs 27.9 ± 6.3°), patella tilt angle (25.9 ± 10.7° vs 9.1 ± 5.2°), and bisect offset ratio values (0.9 ± 0.3 vs 0.5 ± 0.1), and significantly lower in craniocaudal extent (13.7 ± 5.3mm vs 16.7 ± 5.1 mm) and cross-sectional area ratio values (0.07 ± 0.02 vs 0.05 ± 0.02).Conclusions The results showed that the abnormality of VMO were clearly present in recurrent LPD patients compared with normal people, which may be an important factor of patella tilt in LPD patients, so it is necessary to focus on injury condition of VMO during preoperative evaluation.
