The aim of the present study was to investigate the association between the patellofemoral pain syndrome and the clinical static measurements: the rearfoot and the Q angles. The design was a cross-sectional, observational, case-control study. We evaluated 77 adults (both genders), 30 participants with patellofemoral pain syndrome, and 47 controls. We measured the rearfoot and Q angles by photogrammetry. Independent t-tests were used to compare outcome continuous measures between groups. Outcome continuous data were also transformed into categorical clinical classifications, in order to verify their statistical association with the dysfunction, and χ2 tests for multiple responses were used. There were no differences between groups for rearfoot angle [mean differences: 0.2º (95%CI -1.4-1.8)] and Q angle [mean differences: -0.3º (95%CI -3.0-2.4). No associations were found between increased rearfoot valgus [Odds Ratio: 1.29 (95%CI 0.51-3.25)], as well as increased Q angle [Odds Ratio: 0.77 (95%CI 0.31-1.93)] and the patellofemoral pain syndrome occurrence. Although widely used in clinical practice and theoretically thought, it cannot be affirmed that increased rearfoot valgus and increased Q angle, when statically measured in relaxed stance, are associated with patellofemoral pain syndrome (PFPS). These measures may have limited applicability in screening of the PFPS development.

ABSTRAK Patellofemoral pain syndrome tidak memikili definisi gejala yang jelas karena gejala dan sakit yang dirasakan pasien mungkin berbeda dan rata-rata mengganggu aktivitas fisik pasien. Salah satu konsep penting dalam patellofemoral joint adalah Q-angle. Secara teoritis, lebih tinggi Q-angle meningkatkan tarikan lateral paha depan femoris pada patella dan mempotensiasi gangguan patellofemoral. Penelitian ini dilakukan untuk mengevaluasi hubungan antara nyeri lutut anterior dan Q-angle. Pengukuran pada penelitian ini dilakukan dengan menggunakan kujala score untuk mengukur keluhan patellofemoral pain syndrome, untuk mengukur besar sudut Q-angle diukur dengan goniometer. Data yang dikumpulkan kemudian dianalisis menggunakan uji Spearman Rho. Hasil penelitian menunjukan adanya hubungan Q-angle dan patellafemoral pain syndrome pada pemain bola basket wanita. Nilai p value dari Q-angle sebesar 0,024 sehingga Ho ditolak dengan nilai r = 0,579 menunjukan hubungan positif dan kekuatan korelasi yang tinggi, patellofemoral pain syndrome 0,043 dengan nilai r = 0,528 menunjukan hubungan positif dan kekuatan korelasi yang kuat. Nilai korelasi tersebut menunjukkan terdapat hubungan Q-angle terhadap keluhan patellofemoral pain syndrome.

In a retrospective review of 102 patients treated for chondromalacia pa-tellae and patellofemoral pain syndrome/retropatellar dysplasia (PFPS/RPD), the effectiveness of semiflexible foot orthoses was investigated. The combined disorders were diagnosed in 89.3% of the patients. Subjects were 46 women and 54 men, aged 12 to 87 years (mean, 37.9 years; SD, 15.9), who exhibited excessive forefoot varus or rearfoot varus. The initial screening and clinical diagnosis were based on an examination by an orthopedist. Particular attention was directed to patellar crepitation, patellofemoral malalignment, Q-angle measurements, limitation of range of motion, and knee effusion. Patients were evaluated for the onset and duration of patellofemoral pain and degree of knee joint disease. Semiflexible orthoses for each subject were fabricated, based on a clinical lower extremity biomechanical examination. At their follow-up visit, 76.5% were improved and 2% were asymptomatic, showing a significant decrease in the level of pain with orthoses intervention (chi-square P < .001). Although multiple treatment modalities are used for these patients, the results suggest that the use of semiflexible orthoses is significant in reducing symptoms of PFPS/RPD.

<p class="abstract"><strong>Background:</strong> Objective of the study was to evaluate the correlation between rearfoot posture to Q-angle in patients with patellofemoral pain syndrome.</p><p class="abstract"><strong>Methods:</strong> This is a two-year prospective observational study in which all patients with patellofemoral pain syndrome in the age group of 20-30 years were included in the study. The static Q-angle and the rearfoot angles of these subjects were measured and analyzed statistically for their correlation.<strong></strong></p><p class="abstract"><strong>Results:</strong> There were sixty patients who fulfilled the inclusion criteria of the study. Pearson product moment correlation showed 27% subjects having rearfoot valgus and 73% having rearfoot varus angle.

Petellofemoral pain syndrome (PFPS) tidak memiliki definisi yang jelas tentang bagaimana gejala dan letak nyeri yang dirasakan seseorang yang mengalaminya. Diketahui PFPS memiliki hubungan terhadap besar sudut otot quadriceps atau Q angle. Namun masalahnya masih belum spesifik berapa besar Q-angle yang memiliki resiko terhadap PFPS. Penelitian ini dimaksudkan untuk mencari tahu hubungan antara besar q-angle dengan resiko PFPS. Untuk mngetahui adanya PFPS dapat dilakuka dengan Clarke's test, sedangkan untuk mengukur besar sudut Q-angle diukur dengan goniometer. Subyek penelitian mengambil dari pemain basket Universitas Muhammadiyah Surakarta. Data yang dikumpulkan kemudian dianalisis menggunakan uji Spearman Rho. Hasil penelitian menunjukan adanya hubungan Q-angle dan patellafemoral pain syndrome pada pemain bola basket wanita. Nilai p value dari Q-angle sebesar 0,024 sehingga Ho ditolak dengan nilai r = 0,579 menunjukan hubungan positif dan kekuatan korelasi yang tinggi, patellofemoral pain syndrome 0,043 dengan nilai r = 0,528 menunjukan hubungan positif dan kekuatan korelasi yang kuat. Hasil penelitian ini menunjukkan terdapat hubungan Q-angle terhadap keluhan patellofemoral pain syndrome.

Background: The relationship between one-leg static standing balance (OLSSB) and patellofemoral pain syndrome (PFPS) is unknown. Hypothesis: OLSSB decreases in patients with PFPS. Design: Prospective case series. Methods: Fifty-two women with unilateral PFPS were enrolled in this study. OLSSB was evaluated with a stabilometer. Q angle was measured with a lengthened-arm universal goniometer. Lower extremity alignment was analyzed with full-length standing anteroposterior teleroentgenograms. Quadriceps and hamstring strength was measured on an isokinetic dynamometer. Results: There were significant differences in OLSSB, Q angle, and strength of quadriceps and hamstring between the symptomatic and asymptomatic sides. There was a correlation between the strength of the quadriceps and hamstring and OLSSB, while there was no correlation between OLSSB and the severity of pain, lower extremity alignment, and Q angle on the symptomatic side. Conclusions: OLSSB and quadriceps and hamstring strength decreased and Q angle increased on the symptomatic side in PFPS patients. A relationship between OLSSB and pain, Q angle, and lower extremity alignment was not detected, while there was a correlation between the strength of the quadriceps and hamstring and OLSSB. Clinical Relevance: A quadriceps and hamstring strengthening may be beneficial to improve OLSSB in patients with PFPS.

Patellofemoral pain syndrome is a common musculoskeletal condition and a major cause for anterior knee pain. It has been associated with excessive compression between the patella and the lateral femoral condyle. It is one of those overuse disorder that can limit activity of daily living along with participation in sports. The prevalence is more on female than those of male with the ratio of 2:1 and it affect athletic female more solely due to greater internal rotation of femur during running which leads to greater hip adduction. The reason for patellofemoral pain syndrome have been multifactorial increased femoral internal rotation, decreased hip abduction and external rotation strength, decreased VMO function and lateral retinaculum tightness. These factor leads to increase in dynamic Q angle that directly increases patellofemoral contact pressure which map a way to patellofemoral pain syndrome. The literature will have an explanation about altered hip kinetics, kinematics and its association with patellofemoral pain syndrome along with rehab protocol for patients with the same condition.
