Skiing is a sport of technical skill that requires a significant muscular effort. In the last two years due to Covid restrictions there have been severe limitations and upon reopening of ski resorts many people returned to sport without the necessary preparation. We are talking about all winter sports including snowboarding practiced mainly by young people.

What are the joints most stressed in skiing and snowboarding?

The knee is frequently affected in skiing while the shoulder and wrist are more prone to trauma in snowboarding. Anterior cruciate ligament injuries are very common among knee injuries. The knee is also frequently affected by cartilage problems, which can affect people of any age and are of particular importance in young patients who lead an active life. It is known that cartilage has poor regenerative possibilities due to the absence of blood, lymphatic and nervous support that can guarantee a repair of the injured tissue. For this reason, long-term cartilage lesions progress towards degeneration of the articular surface, leading to overt arthritis pictures that involve a limitation of joint function and represent a high social cost. In snowboarding, many injuries concern the upper limbs and in particular the shoulder, elbow and wrist, sometimes it is necessary to operate but sometimes healing can be achieved through regenerative medicine, for example by using plasma enriched with platelets.

What is the P.R.P.?

Platelet Rich Plasma or P.R.P. is obtained from a normal collection of venous blood processed according to a special centrifugation procedure in order to obtain a concentration of platelets (up to 4 times compared to the basic blood value) that contains numerous and important growth factors (PDGF, TGF-B , IGF I / II, FGFB, EGF) capable of stimulating various cellular mechanisms including angiogenesis (development of new vessels starting from existing ones), chemotaxis of macrophages and tissue progenitor cells, proliferation and migration of fibroblasts and collagen synthesis, ultimately promoting tissue healing, repair and regeneration processes. The target cells for the action of growth factors also include chondrocytes (cells of cartilage tissue) and synoviocytes (cells of the membrane and synovial fluid). Currently, clinical studies have demonstrated the advantage of “white blood cell poor” PRP over “white blood cell rich” PRP for tendon healing and osteoarthritis treatment.
