Meniscal Repair With Iliotibial Band Grafting and Collagen Membrane Wrapping Augmentation.

This work contains a description of the modified Henning operation. This technique can be proven especially useful in difficult cases of damaged meniscus (complex injuries). It consists of three stages: stable suturing of the meniscus, placement of the graft from the iliotibial band on the meniscus, and covering the graft with a collagen membrane.

[Biological strategies supporting the orthopaedic treatment].

Damage to the musculoskeletal system significantly impairs mobility and quality of life, limiting everyday activities. For a successful orthopedic treatment, anatomical, physiological and biomechanical factors must be taken into account as they all influence tissue healing. It is therefore of crucial importance to support traditional treatment with biological therapies, as they facilitate the regeneration of the tissue microarchitecture.

[Effects of massage on delayed-onset muscle soreness].

Introduction: Delayed onset muscle soreness (DOMS) is the pain or discomfort often felt 12 to 24 hours after exercising and subsides generally within 4 to 6 days. Once thought to be caused by lactic acid buildup, a more recent theory is that it is caused by inflammatory process or tiny tears in the muscle fibers caused by eccentric contraction, or unaccustomed training levels. Exercises that involve many eccentric contractions will result in the most severe DOMS.
