    According to the BMA guide to sport injuries [1], shoulder injuries in water sport athletes rank in the top five most common injuries. These include shoulder joint injuries with and without dislocation, rotator cuff injuries, disorders of the tendons (tendinitis) and arthritis.

    These clinical pictures may have or may acquire degenerative and inflammatory components. To avoid the indicated surgery, where applicable, but also as follow-up treatment after surgery, another treatment that can be used alongside and supplementary to the generally accepted indicated treatments is infiltration with various substances. Corticoids were and are popularly used for injection treatments. Both the corticoids and local anaesthetics are effective in treating acute pain but are also reputed to be potentially cytotoxic and to hinder healing. On the other hand, the supply of oxygen and nutrients to damaged structures and their metabolic and structural integrity must be rapidly restored. Are there any (biological) alternatives?

    Blood cell secretome (BCS)

    BCS (Orthokine) is a cell-free cocktail of all the factors quantitively released from the blood cells during coagulation. These factors initiate regeneration/wound healing after wound closure. They are released under controlled conditions at 37 oC using the medical device EOT II. Although the healing effect cannot be attributed to one single factor alone, the role of the various growth factors in BCS in tissue healing has been established (e.g. TGF, HGF, IGF, PDGF, FGF). Other BCS components to which an effect can be attributed are cytokines, lipid mediators and extracellular vesicles.

    Case study shoulder injury

    Fig. 1 Before treatment: MRI of the affected left shoulder. Clearly visible bursitis and joint effusion as well as damage to the supraspinatus tendon.

    A female water polo player (29) presented at our practice with pain and loss of strength in her left shoulder. She usually trained 6 times a week and had already struggled painfully through her last matches. Clinically, ultrasound showed well marked subacromial bursitis, which was apparently not caused by trauma, and a partial supraspinatus tendon tear in the left shoulder (see also Fig.1). She received conservative treatment with targeted physiotherapy and osteopathy to improve/optimise function/biomechanics over a period of two months with concomitant gentle loa­ding and cooling treatment. Puncture of the subacromial bursa and 1x subacromial bursa infiltration with corticoids were also performed.

    Four weeks after the corticoid infiltration, BCS was infiltrated four times on the supraspinatus tendon under ultrasound control (every 3 – 4 days, 2 mL per infiltration). After the first infiltration, the patient already reported reduced pain, after the third, freedom from pain at rest, and after the fourth, only minimal pain under loading. Additional concomitant measures inclu­ded function analysis, function training and dry needling. Ultrasound follow-up after three months showed marked structural improvement in the supraspinatus tendon. The patient continues to report freedom from pain under full loading. We attach ultrasound images for information purposes (Figs. 2 and 3), being well aware that ultrasound images are not compa­rable to ”initial MRI images“.

    Currently available studies on BCS

    A study on supraspinatus tendinopathy published in 2018 shows that infiltration with BCS is markedly superior to a corticoid in the medium term [2]. A series of earlier studies show improved healing of tendons and muscles with BCS in both humans and animals [3 – 7]. These studies show histologically well marked improvement in tissue structure and, where investigated, significantly improved clinical findings. According to the currently available data, BCS improves the local metabolic environment inter alia by normalising cell physiology and reducing local oxygen radical formation. This allows local stem cells and macrophages to be active in tissue regeneration [8,9]. This pro­perty is also beneficial for acute and chronic joint injuries [10,11]. Post-operative treatment with BCS is also possible and significantly improves the outcome post ACL reconstruction [11].

    Conclusion

    BCS is effective in soothing the painful inflammatory process (as in the des­cribed case) and, unlike corticoids, initiates regeneration of the damaged tissue. As the maintenance of the structure and function of the rotator cuff is crucial to the health of the shoulder joint, local BCS infiltrations are avai­lable as a supplement to the indicated established treatments to achieve a rapid and reliable return to match fitness.
