- Background:Jumper’s knee is a common and troublesome condition among senior volleyball players, but its prevalence among elite junior players compared to matched non-sports active controls is not known.Objective:To clinically, and by sonography, examine the patellar tendons in elite junior volleyball players (15–19 years) at the Swedish National Centre for volleyball and in matched controls.Methods:The patellar tendons in the 57 students at the Swedish National Centre for high school volleyball and in 55 age, height, and weight matched not regularly sports active controls were evaluated clinically and by grey scale ultrasonography (US) and power Doppler (PD) sonography.Results:There were no significant differences in mean age, height, and weight between the volleyball players and the controls. In the volleyball group, jumper’s knee was diagnosed clinically and by US in 12 patellar tendons (10 male and two female). In 12/12 tendons, PD sonography demonstrated a neovascularisation in the area with structural tendon changes. In another 10 pain free tendons, there were structural tendon changes and neovessels. In the control group, no individual had a clinical diagnosis of jumper’s knee. US demonstrated structural tendon changes in 11 tendons, but there was no neovascularisation on PD sonography.Conclusions:A clinical diagnosis of jumper’s knee, together with structural tendon changes and neovascularisation visualised with sonography, was seen among Swedish elite junior volleyball players but not in matched not regularly sports active controls. Structural tendon change alone was seen in 10% of the control tendons.

- Background: Delayed Achilles tendon ruptures leaving large defects are difficult to treat, and the potential for tendon regeneration is thought to be limited. Furthermore, post-operative wound healing problems, sometimes including infections, can be challenging to treat and negatively affect rehabilitation.Case Presentation: This 74-year-old lady suffered from insertional Achilles tendinopathy. After treatment with a local cortisone injection, she sustained a total insertional Achilles tendon rupture. This rupture was treated conservatively, and after treatment the Achilles re-ruptured in the insertional area. The rupture was then treated with re-insertion into the calcaneal insertion. Early in the post-operative period the patient sustained a deep surgical wound infection and sepsis. Because of poor effect of treatment with antibiotics, and total tendon destruction, the whole Achilles was extirpated. After extirpation there was immobilization in a cast followed by mobilization and gradually increased loading. At a one-year follow-up, the patient was walking without a limp, could do heel-raise halfway up standing on one leg, there was a palpable Achilles tendon and ultrasound scanning showed a structure very similar to a slightly thickened and tendinopathic Achilles tendon. There was an obvious regeneration of the whole Achilles tendon, and the tendon function was surprisingly good.Conclusion: This case study clearly shows the regeneration potential in the Achilles tendon and provides significant knowledge of importance for clinicians dealing with Achilles tendon injuries.

- BACKGROUND: Recent studies have revealed structural changes with neovessels in patients with jumper's knee and Achilles tendinopathy, and treatment with sclerosing injections has shown promising clinical results. PURPOSE: To study the prevalence of neovascularization and structural tendon changes on color Doppler ultrasound examination in elite athletes with clinical symptoms of jumper's knee and to examine the ultrasound characteristics of the tendon after sclerosing injection treatment with polidocanol. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The authors recruited patients among elite athletes with a clinical diagnosis of jumper's knee who participated in a previous randomized clinical trial. The patients recorded knee function using the Victorian Institute of Sport Assessment score. Patients were examined by color Doppler ultrasound at baseline and, for patients with structural changes and neovascularization who received sclerosing treatment, after treatment. RESULTS: Sixty-three patients (11 women and 52 men) with 79 symptomatic tendons were studied. The ultrasound examination revealed that neovascularization was present in 48 of the 79 tendons (60%). Of 33 patients (43 tendons) who received sclerosing injections, 29 patients (37 tendons, 86%) were examined 37 (19 to 53) weeks after their final sclerosing injections. Of these, 7 tendons (18.9%) had no change in neovascularization after treatment, 21 tendons (56.8%) had less neovascularization, and 9 tendons (24.3%) had more visible neovascularization. There were no significant differences in the change in Victorian Institute of Sport Assessment score between patients who had less, more, or unchanged neovascularization after treatment (analysis of variance, P = .9). CONCLUSION: About two thirds of patients with jumper's knee can be expected to have structural tendon changes with neovascularization. There was no relationship between changes in ultrasound characteristic and knee function after sclerosing treatment.

- Background:A recent study reported promising clinical results using eccentric quadriceps training on a decline board to treat jumper’s knee (patellar tendinosis).Methods:In this prospective study, athletes (mean age 25 years) with jumper’s knee were randomised to treatment with either painful eccentric or painful concentric quadriceps training on a decline board. Fifteen exercises were repeated three times, twice daily, 7 days/week, for 12 weeks. All patients ceased sporting activities for the first 6 weeks. Age, height, weight, and duration of symptoms were similar between groups. Visual analogue scales (VAS; patient estimation of pain during exercise) and Victorian Institute of Sport Assessment (VISA) scores, before and after treatment, and patient satisfaction, were used for evaluation.Results:In the eccentric group, for 9/10 tendons patients were satisfied with treatment, VAS decreased from 73 to 23 (p<0.005), and VISA score increased from 41 to 83 (p<0.005). In the concentric group, for 9/9 tendons patients were not satisfied, and there were no significant differences in VAS (from 74 to 68, p<0.34) and VISA score (from 41 to 37, p<0.34). At follow up (mean 32.6 months), patients in the eccentric group were still satisfied and sports active, but all patients in the concentric group had been treated surgically or by sclerosing injections.Conclusions:In conclusion, eccentric, but not concentric, quadriceps training on a decline board, seems to reduce pain in jumper’s knee. The study aimed to include 20 patients in each group, but was stopped at the half time control because of poor results achieved in the concentric group.
