The effect of percutaneous release of the medial collateral ligament in arthroscopic medial meniscectomy on functional outcome.

Background: Pie crusting (PC) of the medial collateral ligament (MCL) in the knee has been used empirically to achieve more space in the medial compartment during knee arthroscopy. However, there are no reported studies analyzing the functional results of the application of the PC technique to the MCL in patients undergoing arthroscopic meniscectomy of the medial meniscus, and to determine the rate of iatrogenic injury and associated morbidity.

Description Of Technique: The patient was in a supine position with a tourniquet and a side post.

Multidimensional analysis of treatment adherence in patients with multiple chronic conditions. A cross-sectional study in a tertiary hospital.

Objective: Determine treatment adherence in patients with multiple chronic conditions (MCC).

Methods: A random patient sample ≥ 15 years, discharged from hospital with ≥1 chronic conditions (CC) was interviewed after 6-12 months. Analysis included variables in 5 dimensions (WHO): socio-demographics, disease, treatment, patient and health system characteristics.

Cryopreserved and frozen hyaline cartilage imaged by environmental scanning electron microscope. An experimental and prospective study.

Objective: To obtain images of the articular surface of osteochondral grafts (fresh, frozen, and cryopreserved in RPMI) using an environmental scanning electron microscope (ESEM). To evaluate and compare the main morphological aspects of the chondral surface of the fresh, frozen, and cryopreserved grafts as visualized via ESEM.

Methods: The study was based on osteochondral fragments from the internal condyle of the knee joint of New Zealand rabbits, corresponding to the chondral surface from fresh, frozen, and cryopreserved samples.
