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.

The objective of this study was to utilise an ultrasonic technique to assess the effect of patellofemoral pain syndrome (PFPS) on the mechanical properties of the patellar tendon. Seven subjects with PFPS and seven matched control subjects volunteered to participate in this study. Subjects were asked to perform isometric maximal voluntary contractions of the knee extensors while their knee extension torque was monitored and the displacement of the patellar tendon was recorded with an ultrasonic system. Our results showed significantly lower tendon stiffness (by ∼30%) in the PFPS subjects. Although tendon secant modulus was lower by 34% in the PFPS subjects, the difference was not statistically significant. Therefore, we conclude that the ultrasonic technique was able to detect a decrease in the structural stiffness of the patellar tendon associated with PFPS. The decrease in tendon stiffness was moderately correlated with the length of symptoms in these individuals.

Background: Active rehabilitation has an important role in the management of patellofemoral pain syndrome (PFPS). Although some studies have shown the benefit of hip-muscle strengthening, the effect of combining hip-muscle stretching with strengthening has not yet been defined. Purpose: To evaluate the effect of combined strengthening of the hip external rotators and abductors and stretching of the hip internal rotators on pain and function in patients with PFPS. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: A total of 109 patients with PFPS (75 female and 34 male; mean age, 31.6 ± 10.8 years) were first randomly assigned to protocol A (n = 67) of the A-B arm (AB group; standard rehabilitation) or protocol B (n = 42) of the B-A arm (BA group; standard rehabilitation with strengthening of the hip external rotators and abductors and stretching of the hip internal rotators). Each protocol consisted of 3 sessions a week for 4 weeks. After a washout period, corresponding to a symptom-free period, rehabilitation programs were crossed over. A visual analog scale (VAS) evaluating perceived pain, the Functional Index Questionnaire (FIQ), and the Kujala score were administered at baseline, the end of each rehabilitation protocol, and 12 weeks after the completion of the second protocol for each group. Results: Until the final follow-up, VAS, FIQ, and Kujala scores were significantly improved in both the A-B and B-A arms ( P < .05 for all). Compared with protocol A, protocol B provided significant improvement in terms of pain and function in both the BA (VAS and Kujala; P < .001) and AB (VAS and Kujala; P < .001) groups. Conclusion: Combined strengthening of the hip abductors and external rotators with stretching of the hip internal rotators provided better outcomes, which were maintained for at least 12 weeks, in terms of pain and function in patients with PFPS.
