Purpose: Changes in tendon structure are commonly seen in patients with unilateral achilles (AT) or patellar (PT) tendinopathy but might also be present on the asymptomatic side, indicating a higher risk for developing symptoms. The aim of this study is to compare tendon structure of the symptomatic side with the asymptomatic side in AT and PT patients and control subjects. Methods: A total of 46 patients with unilateral AT (16 insertional and 30 midportion) and 38 with unilateral PT were included. For the control group, a total of 18 Achilles tendons and 25 patellar tendons were scanned. Tendon structure was assessed using ultrasound tissue characterisation (UTC), which quantifies tendon organisation dividing the structure into four different echo types (I–IV). Results: There were significant differences in echo types I, III, and IV between symptomatic and asymptomatic sides and controls. Additionally, there was a significant difference between the symptomatic and the asymptomatic side for all tendinopathy locations. In the insertional AT tendon portion, the symptomatic side showed a higher percentage of echo type III. For the midportion AT, the symptomatic side showed a lower percentage of echo type I and a higher percentage of echo types III and IV. For the patellar tendon, the symptomatic side showed a higher percentage of echo types III and IV. All differences were higher than the minimal detectable changes. Conclusion: Although patients have symptoms unilaterally, the tendon structures are compromised on both sides. These results stress the importance of monitoring both symptomatic and asymptomatic tendon structures and in addition highlight that the asymptomatic side should not be used as reference in clinical practice.

Purpose: The aim of the study was to compare the effectiveness of focused shockwave therapy (FSWT) and radial shockwave therapy (RSWT) for treating patellar tendinopathy. Methods: Patients were randomized into two groups. One group received three sessions of FSWT, and the other group received three sessions of RSWT. Both groups also received an eccentric training programme. Follow-up measurements took place 1, 4, 7 and 14 weeks after the final shockwave treatment. The primary outcome measure was the Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire. Secondary outcome measures were pain during ADL, sports activities and the decline squat. Results: Forty-three subjects (57 tendons) were included in the study. Twenty-one subjects (31 tendons) received FSWT, and 22 subjects (26 tendons) received RSWT. Both groups improved significantly on the VISA-P score, but there were no differences in improvement between the FSWT group (15 points on the VISA-P) and the RSWT group (9.6 points, n.s.). This was also the case for the secondary outcome measures. Conclusion: There were no statistically significant differences in effectiveness between FSWT and RSWT. It is therefore not possible to recommend one treatment over the other on grounds of outcome. Both groups improved significantly, although it is questionable whether this difference is clinically relevant. Level of evidence: II. [ABSTRACT FROM AUTHOR]

In order to gain insight into the management of patients with vascular malformations (VM) in the University Hospital Nijmegen in the past 10 years, 151 cases managed by different specialists were reviewed. To avoid the usual confusion in terminology, all recorded diagnoses were reclassified according to the biological classification of Mulliken. The sex distribution was equal; 79% of the malformations were diagnosed at birth or in the 1st year of life. The median time between presentation and consultation was 3 years. Sixty-two lymphatic, 26 venous, 24 capillary, 1 arterial, and 38 combined malformations (8 arteriovenous, 30 others) were found. The head and neck region was most frequently involved, followed by the lower and upper limbs and trunk. The pediatric surgeon was the most frequently consulted specialist. Confusing, mutually incompatible terminology and a wide variety of different diagnostic techniques and treatments had been used by the different specialists. To improve the management of patients with vascular malformations, the use of a uniform classification, an increase in basic investigations, and the development and evaluation of protocols for diagnosis and treatment by multidisciplinary teams are necessary.
