Before And After

Objective: Patellofemoral Pain Syndrome (PFPS) is one of the most common disorders of the knee joint. It is characterized by pain, reduced proprioception, and altered pattern of vastus muscle activation, which effectively maintain the balance needed for performing daily living activities such as walking and running. One treatment method that can reduce pain and improve balance in people with PFPS is Kinesiology Taping (KT). Considering the physiological and anatomical differences in the knee structure of men and women and the importance of studying the effect of KT on the dynamic balance of men with PFPS, this study aims to compare the effect of KT on dynamic balance and pain of men and women with unilateral PFPS. Materials & Methods: This is a quasi-experimental and non-randomized clinical trial. The participants were 30 males and 31 females aged 18-40 years suffering from unilateral PFPS. They were recruited using a convenience sampling method. First, the subjects performed the Y-balance test three times in each of the anterior, posteromedial, and posterolateral directions. The maximum score obtained from the three repetitions in each direction was divided by the limb length and recorded in percentage as a dynamic balance score. After 5 minutes of rest and performing initial tests, the subjects performed the intervention. In this stage, KT with a tension equal to 50%-75% of its initial length was applied on the patella of the involved limb to cause medial glide. The effectiveness of KT was examined under a single-leg squat-test. For this purpose, all subjects performed unilateral squatting on their affected leg for 10 seconds with 45 degrees of knee flexion before and after KT, while their pain level was recorded using the visual analog scale. In case of a 50% reduction in pain, the subjects were allowed to enter the final stage (performing the Y-balance test); otherwise, patellar taping was repeated to obtain the appropriate pain reduction. Results: Within-group comparison of balance parameters before and after KT using the paired t-test showed an increase in the reach distance at three directions in the Y-balance test, revealing a significant improvement in the dynamic balance following KT (P<0.05). According to the independent t-test results, there was no significant difference in balance parameters between males and females before and after the intervention (P>0.05). Moreover, the pain was significantly reduced in both genders after KT (P<0.05), but its difference between men and women was not statistically significant (P>0.05). Conclusion: KT is an appropriate therapeutic intervention for improving dynamic balance and reducing pain in people with PFPS. It seems that KT has the same effect on dynamic balance and pain of women and men with PFPS.

The Difference

Background Patellofemoral pain syndrome is the most common knee condition and is associated with patellar maltracking. Ultrasound is used in studying patellar maltracking. The objective is to determine if the technique which analyzes the displacement of the patellar tendon in the trochlear sulcus is associated with patellofemoral pain syndrome. Methods In total, 68 knees of 34 football players (males = 20, females = 14) were included. Patellar tendon displacement was assessed in supine and standing positions. Patellar tendon displacement difference in the two positions was determined. Results There was a significant difference in the lateral patellar tendon displacement during standing which was larger in patellofemoral pain syndrome than without patellofemoral pain syndrome (Mean Rank = 39.20 vs. 30.32, p = 0.02). There was no significant difference between the two groups for lateral patellar tendon displacement in supine and the difference in patellar tendon displacement from supine to standing. Conclusion The technique could be a potential method in assessing patellar maltracking. It could be used to have a comprehensive understanding of the pathomechanics and treatment of patellofemoral pain syndrome.

Dynamic Valgus

Background: Patellofemoral pain syndrome (PFPS) is sometimes related to excessive hip adduction and internal rotation, as well as knee valgus during weightbearing activities in females. Research on injury prevention and rehabilitation strategies has shown the positive effects of valgus control instruction (VCI) exercise programs in training. Hypothesis: A VCI program would result in a positive change in pain, eccentric hip muscle torque, and performance in females with PFPS. Study Design: Controlled laboratory study. Level of Evidence: Level 1. Methods: Sixty-four amateur female volleyball players from our university (age, 18-25 years) with PFPS and equal years of exercise experience were randomly divided into VCI (n = 32; age, 22.1 ± 5.88 years) and control (n = 32; age, 23.1 ± 6.49 years) groups. Function (single, triple, and crossover hops), strength (hip abductor and external rotators), pain (visual analog scale), and knee valgus angle (single-leg squat) were assessed at baseline and after intervention. Results: There was a significant difference before and after implementation of the VCI program with regard to pain (49.18% ↓, P = 0.000), single-leg hop test (24.62% ↑, P = 0.000), triple-hop test (23.75% ↑, P = 0.000), crossover hop test (12.88% ↑, P = 0.000), single-leg 6-m timed hop test (7.43% ↓, P = 0.000), knee dynamic valgus angle (59.48% ↓, P = 0.000), peak abductor to adductor eccentric torque ratio (14.60% ↑, P = 0.000), peak external (59.73% ↑, P = 0.023) and internal rotator (15.45% ↑, P = 0.028) eccentric torques, and the ratio of peak external to internal rotator eccentric torque (40.90% ↑, P = 0.000) ( P < 0.05). Conclusion: PFPS rehabilitation and prevention programs should consider VCI exercises to decrease pain, improve strength, and increase athletes’ functional performance. Clinical Relevance: This study investigated the effect of VCI exercises on knee valgus angle, pain, and functionality of individuals with PFPS. The VCI program improves performance, knee dynamic valgus angle, and strength in participants with PFPS. A controlled and optimal knee valgus angle during a functional task is the most important factor for injury prevention specialists. VCI training can be used as a supplemental method to prevent and treat lower extremity injury in patients with PFPS.

Background There is controversy regarding the relationship between patellofemoral pain syndrome (PFPS) and insufficiency of the vastus medialis obliquus (VMO). The conventional clinical practice of VMO strengthening for PFPS has been challenged for lack of evidence. The purpose of this study was to observe the difference in sonographic findings of the VMO between patients with PFPS and healthy adults. Hypothesis The morphological characteristics of the VMO are different between patients with PFPS and healthy adults. Study Design Case-control study; Level of evidence, 3. Methods Fifty-four patients with PFPS and 54 age-, gender-, body height—, and body weight—matched healthy adults as controls were enrolled in the study to measure by sonography the insertion level, fiber angle, and volume of the VMO at its insertional portion to detect differences between patients with PFPS and healthy controls. Results The insertion level, fiber angle, and VMO volume were all significantly smaller in the PFPS group than in the control group (P < .05). Multivariate analysis of variance has revealed a Wilks λ value of .845 and an F value of 5.640 (P = .001). Conclusion There was a significant difference in the 3 VMO measures between patients with PFPS and the healthy controls. Individuals might be predisposed to PFPS by different VMO characteristics, including insertion level and fiber angle. The current study cannot determine whether the observed morphological differences were the results of atrophy in response to pain or if they represent dysplasia that was predisposed to pain development. The clinical manifestations of VMO characteristics should be thoroughly investigated in other populations. Clinical Relevance The function of the VMO is important to consider in the rehabilitation of patients with PFPS.
