Clinical TrialTreatment of midportion Achilles tendinosis: similar clinical results with US and CD-guided surgery outside the tendon and sclerosing polidocanol injections.
Sclerosing polidocanol injections targeting the area with vasculo/neural ingrowth on the ventral side of the tendon have previously been demonstrated to give good clinical results in patients with chronic painful midportion Achilles tendinosis. In this study, 20 consecutive patients (9 men and 11 women, mean age 46 years) with chronic painful midportion Achilles tendinosis were treated with either sclerosing polidocanol injections (Group A) or open surgical revision of the area with vasculo/neural ingrowth on the ventral side of the Achilles tendon (Group B). Before treatment, all patients had structural tendon changes and increased blood flow-neovascularisation demonstrated with US and colour Doppler. ⋯ There was one deep infection in Group B. At the 6 months follow-up, 6/9 patients in Group A, and 10/10 patients in Group B were satisfied. In summary, both treatment with sclerosing polidocanol injections and open surgical revision outside the ventral Achilles midportion show promising short-term clinical results.

Technical note: the "double eye" technique as a modification of autologous chondrocyte implantation for the treatment of retropatellar cartilage defects.
Retropatellar cartilage defects treated with autologous chondrocyte implantation (ACI) are still associated with inferior clinical outcome compared to defects being located on the femoral condyles. This is partly because of the biomechanical characteristics of the patellofemoral section of the joint, in which, in contrast to the medial or lateral compartments of the knee joint, prejudicial shearing forces are dominant. The patellar ridge has a particularly important role in the reduction of these shearing forces. ⋯ Objective evaluation according to the criteria of the IKDC score showed very good or good treatment results in 9 of the 11 cases, with only 2 poor results. In conclusion, with the double eye modification presented in this paper, the potential for successful results in the treatment of combined cartilage defects of the medial and lateral facets of the patella is high; it takes into account the specific biomechanical properties of the patella ridge. The procedure needs further evaluation in clinical studies involving larger numbers of patients so that the indications can be determined more precisely.
