“…For BPII 2.0, ICC values ranged from 0.89 and 0.98 in the Indonesian translation, 0.89 in the German translation, 0.97 in the Swedish translation, 0.87 in the Norwegian translation and 0.97 in the original study. [ 9 , 18 , 22 – 24 ]. The fact that there are 7–10 days between the two questionnaires and that there is no change in the knee conditions of the patients in this interval may indicate the accuracy of the high value obtained by the literature.…”

“…Patient-reported outcome measurements (PROMs) are valuable instruments for evaluating the success of the surgery and patient satisfaction. PROMs used before were used to evaluate patellofemoral pain syndrome in which anterior knee pain was in the foreground rather than specifically questioning patellofemoral instability [ 9 ]. Lysholm Knee Scoring Scale, Kujala Score, Fulkerson Patellofemoral Score, and the International Knee Documentation Committee form are generally used to assess knee disorders [ 10 – 13 ].…”

Background Current treatment options for patellofemoral (PF) instability have required functional scoring systems. The Banff Patellar Instability Instrument (BPII) 2.0 and Norwich Patellar Instability (NPI) scores were explicitly created to meet the need to evaluate PF instability. Different patient-reported outcome measurements (PROMs) are used to evaluate anterior knee problems. Objectives To test the validity and reliability of the Turkish version of the BPII 2.0 and NPI score. Study design and methods Fifty-one patients that operated for PF instability, older than eighteen years old, were included in this study. Turkish translation of the BPII 2.0 and NPI scores was undertaken through translation into Turkish by an independent translator. Two tests were repeated seven days apart. Intraclass correlation coefficient (ICC) was used for test–retest reliability. Internal consistency was analyzed using Cronbach's alpha. Validity was assessed by correlating the Kujala and Lysholm knee scores. Results Fifty-one patients (34 females/17 males), the average age was 25 ± 7, were included in this study. Cronbach's alpha value was 0.829 for BPII 2.0 and 0.843 for NPI for the first time answered by patients. ICC values applied to evaluate test–retest reliability were 0.904 (p < 0.05) for BPII 2.0 and 0.915 (p < 0.05) for NPI. There was a moderate correlation between the BPII 2.0 Turkish version and the Kujala score. There was a very high correlation between the Turkish version of the BPII 2.0 and Lysholm knee scores. An excellent negative correlation was found between Norwich and Kujala scores (r = −0.819, p < 0.05). The correlation coefficient between Norwich and Lysholm scores was −0.662, indicating a high negative correlation (p < 0.05). The correlation coefficients between the Turkish version of BPII 2.0 and NPI were −0.533 (p < 0.05). Conclusions The Turkish version of the BPII 2.0 and NPI score is a reliable and valid instrument for Turkish-speaking patients with patellofemoral instability.

“…Validated patient-reported outcome measures (PROM; International Knee Documentation Committee subjective knee form (IKDC), Visual Analog Scale [VAS] for pain, Tegner Activity Scale [TAS], subjective satisfaction with the postoperative result [1–10 scale, 10 = highest satisfaction]) were collected pre- and minimum 24 months postoperatively [ 4 ]. Return to sporting activities as well as the Kujala score were evaluated at follow-up.…”

Purpose The purpose of the study was to report the clinical, functional and radiological outcome following varus osteotomy as a salvage procedure in young to middle-aged patients with patellofemoral arthritis (PFA) and associated valgus malalignment. It was hypothesized that a significant improvement in knee function and reduction in pain would be achieved. Moreover, no conversion to patellofemoral joint arthroplasty could be observed. Material and methods Patients (< 50 years of age) that underwent varus osteotomy between 08/2012 and 01/2020 for the treatment of symptomatic PFA and associated valgus malalignment were consecutively included (minimum follow-up: 24 months). Patient-reported outcome measures (PROM; International Knee Documentation Committee subjective knee form [IKDC]), Visual Analog Scale [VAS] for pain, Tegner Activity Scale [TAS], and satisfaction with the postoperative results (1–10-scale, 10 = highest satisfaction) and weight-bearing whole-leg anteroposterior radiographs were conducted pre- and postoperatively. The change in PROM and femorotibial angle (FTA) were tested for statistical significance. Results In total, 12 patients (14 knees) were included (66.7% female; mean age: 33.8 ± SD 6.6 years). In ten cases, lateral opening-wedge distal femoral osteotomies (DFO) were performed, of which three cases included a concomitant femoral derotation. Three medial closing-wedge DFO and one medial closing-wedge high tibial osteotomy were performed. At follow-up (55.3 ± 29.3 months), a significant improvement in knee function (IKDC: 56.4 ± 14.4 to 69.1 ± 11.2, p = 0.015) and reduction in pain (VAS for pain: 3.5 [interquartile range 2.3–5.8] to 0.5 [0–2.0], p = 0.018) were observed. Patients were able to reach their preoperative sporting activity level (TAS: 3.0 [3.0–4.0] to 3.5 [3.0–4.0], p = 0.854) and were highly satisfied with the postoperative result (9.0 [6.5–10]). Additionally, a significant correction of valgus malalignment was observed (5.0° ± 2.9° valgus to 0.7° ± 3.2° varus, p < 0.001). Regarding complications, two re-osteosyntheses were performed due to loss of correction and delayed union. No conversion to patellofemoral arthroplasty occurred. Conclusion In patients with symptomatic PFA and associated valgus malalignment, varus osteotomy as a salvage procedure achieved a significant improvement in knee function and reduction in pain. No conversion to patellofemoral joint arthroplasty occurred at short- to mid-term follow-up. Level of evidence Retrospective case series, Level IV.

“…Pathologies of the patellofemoral joint are mainly observed in working individuals of young and middle age who lead an active lifestyle, making it socially signifi cant [3,4]. In such cases, patellar displacement relative to the trochlear groove of the femur can be diagnosed [5]. This condition can be caused by congenital lateralization of the tuberosity of the tibia [6] and weakness of the medial vastus muscle of the thigh [7].…”

Aim. To develop a biomechanical model of the knee joint, including a detailed representation of the patellofemoral segment for the normal anatomy of bones, joints, ligaments and muscles, and study patellar movement during passive knee flexion.Materials and methods. The architecture of the biomechanical model was developed using an open source software system for biomechanical modeling OpenSim. Patellofemoral joint with 6 degrees of freedom, patellar stabilizers – medial patellofemoral ligament (MPFL), medial patellotibial ligament (MPTL), lateral retinaculum (LR), and patellar contact surfaces (facets) were included in the model. Gmsh and Paraview were used to generate the contact surfaces. Simulations of knee passive flexion with consistent patellar stabilizers exclusion were carried out to identify their influence on patellar movement.Results. The presented biomechanical model provides a detailed analysis of the normal dynamics of the patella and the role of different anatomical structures in its functioning and can be used for further experiments investigating of the patellar movement. The experiment involving all ligaments is consistent with the physiological norm. Disabling MPTL has minimal effects on patellar tilt and translation, which aligns with its small size. In contrast, deactivating MPFL results in increased lateral tilt and translation of the patella. Additionally, deactivation of LR components 1 and 2 induces more medial tilt and translation. Deactivating LR components 3 and 4 leads to further lateral translation and slight additional medial tilt.Conclusion. Computational results show that all ligaments contribute to the normal movement of the patella. These findings highlight the importance of stabilizing structures in maintaining patellar stability during knee flexion.
