Within a sport, such as hurdling, tenosynovitis is a type of tendinopathy which can occur. Tenosynovitis takes place when a lesion affects or causes abrasion to the sliding surfaces of a tendon and its sheath becomes inflamed (Fowler, 1984). Some tendons are covered by a sheath, these produce fluid that lubricate the tendon. Injury to the tendon can cause the sheath to fail to produce enough fluid, this in turn causes friction and inflammation of the synovium or tenosynovitis (Evans & Farooki, 2001). Tendinitis can cause an enlarged tendon casing and restriction of peroneal tendons, causing stenosing tenosynovitis. There is also a type of infectious tenosynovitis, which is less typical within sport (Tijin A Ton, et al., 1997). Specifically, with peroneus longus and peroneus brevis tenosynovitis, there is an inflammation of the shared tendon sheath,…show more content… Chronic issues produced by overuse can account for 30% of all running associated injuries (Sharma & Maffuilli, 2006). Some conditions of this nature have lingering inflammation, referred to as chronic inflammation. This occurs when macrophages are unable to fully perform phagocytosis (Norris, 2004). This athlete, 6 weeks post injury, falls within the remodelling phase of healing. In this stage, restorative tissues adjust size and are reforming. Repair tissues convert to fibrous from cellular, metabolism is higher, tenocytes and collagen fibres come into line with directions of tension (Hooley & Cohen, 1979). Greater quantities of type I collagen are also being manufactured during this stage (Abrahamsson, 1991) (Sharma & Maffuilli, 2006). Three weeks post injury quantities of collagen should be stabilising, strength increases as replacement collagen and cross bonds are formed. Collagen laydown is influenced by a number of factors; type of tissue injured, age, and amount of scar tissue, position/path of scar and external forces (Van der Meulen, 1982) (Frank, et al.,
