A total of 11 patients (12 knees) with stable lesions of osteochondritis dissecans of the knee underwent arthroscopic fixation of the fragments using polylactide bioabsorbable pins. The site of the lesion was the medial femoral condyle in ten knees and the lateral femoral condyle in two. The mean age of the patients was 14.8 years (12 to 16). At a mean follow-up of 32.4 months (13 to 38 months)...

Ferroelectrets have promoted a variety of exciting flexible sensors, actuators, and microenergy harvesters. However, most ferroelectrets been fabricated from non-degradable petro-based resins, thus the recycling these materials constitutes big challenge. This article reports biodegradable bioabsorbable ferroelectret films made polylactic acid (PLA) resins for highly sensitive transducer applica...
