The Relationship

Abstract Context: The relationship between lower extremity alignment and lower extremity injury risk remains poorly understood, perhaps because most authors have examined only individual or a select group of alignment variables. Examining the relationships among alignment variables may allow us to more accurately describe lower extremity posture and clarify the relationship between lower extremity alignment and injury risk in future studies. Objective: To measure lower extremity alignment variables and examine whether relationships could be identified among these variables. Design: Observational study. Setting: Laboratory. Patients or Other Participants: Two hundred eighteen (102 males: age  =  23.1 ± 3.2 years, height  =  177.3 ± 8.4 cm, mass  =  80.8 ± 13.0 kg; 116 females: age  =  21.8 ± 2.7 years, height  =  163.5 ± 7.4 cm, mass  =  63.4 ± 12.4 kg) healthy, college-aged participants. Main Outcome Measure(s): We measured pelvic angle, femoral anteversion, quadriceps angle, tibiofemoral angle, genu recurvatum, and tibial torsion to the nearest degree and navicular drop to the nearest millimeter on the right and left lower extremities. Separate principal components factor analyses were performed for each sex and side (left, right). Results: A distinct lower extremity factor was identified, with relationships observed among increased pelvic angle, increased quadriceps angle, and increased tibiofemoral angle. A second distinct lower extremity factor was identified, with relationships observed among increased supine genu recurvatum, decreased tibial torsion, and increased navicular drop. Femoral anteversion loaded as an independent third factor. These distinct lower extremity alignment factors were consistent across side and sex. Conclusions: Factor analysis identified 3 distinct lower extremity alignment factors that describe the potential interactions among lower extremity alignment variables. Future authors should examine how these collective alignment variables, both independently and in combination, influence dynamic knee function and risk for lower extremity injuries.

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.
