Background: PRP, obtained from centrifuged autologous blood, contains a large quantity of growth factors, which may enhance the tissue healing processes. Local infiltration of PRP represents a relatively new treatment for tendinopathies. To date, no side effects have been reported after infiltration of PRP to treat tendinopathy. Case report: A 35-year-old patient had a right upper patellar tendinopathy which was resistant to all conservative treatments for more than 6 months. The patient was a type 1 diabetic (well controlled). He had an intratendinous infiltration of 6 mL of PRP (8.105 platelets/mm3, almost no red or white blood cells) after disinfection but without local anaesthetic. Immediately following the infiltration, local cryotherapy was performed for 15 minutes. NSAIDs were avoided, but class-1 or -2 pain-killers were authorised if necessary. A standardised sub-maximal eccentric rehabilitation should have been started 1 week after. However, the patient experienced local swelling with erythema, increased heating and pain which appeared just underneath the patella, but without biological inflammatory syndrome. A great Doppler signal in a thicker patellar tendon was observed by US, but there was no sign of local infectious disease demonstrated by either CT or MRI. However, the local inflammation did not decrease after a progressive 3-week treatment of local cryotherapy, local and oral NSAIDs and colchicine 1 mg. Thus, an insidious infection was suspected, even though there was neither evidence of biological inflammatory syndrome nor sign of infectious lesion on imagery examination. An antibiotic therapy (rifampicine 600 mg + minocycline 100 mg) was initiated for 3 months. Finally, a 3-phase bone scintigraphy suggested the presence of a complex regional pain syndrome type 1 treated by a classical physical therapy and concomitant class-2 pain killers. The evolution was favourable after 6 months of symptomatic treatment, and the pain decreased to a level similar to that before the infiltration of PRP. Discussion/Conclusions: This case report draws attention to potential side effects that are linked to this new therapy by infiltration of platelet rich plasma in case of tendinopathy, in particular when used in patients with type 1 diabetes. Thus, the balance between benefits and risks must be carefully evaluated before using this treatment in patients with type 1 diabetes.

This case report is concerned with a 30 year old patient diagnosed with pigmented villonodular synovitis (PVNS) in the knee. The patient underwent an orthopedic surgical operation to remove the lesions. PVNS is a rare proliferative disorder, mostly benign and affecting the knee; its aetiology remains unclear. It represents a medical challenge because of non-specific symptoms that delay the diagnosis with a very high rate of recurrence. MRI imaging is necessary to explore the lesions, but the final diagnosis can only be made after anatomopathologic analysis of the excised lesions. When multiple lesions are present, the treatment consists of their excision by arthrotomy, or by arthroscopy if the disease is localized. [less ▲]

Platelet-rich plasma (PRP) may represent a new therapeutic option for chronic tendinopathies. Platelets release various cytokines and growth factors which promote angiogenesis, tissue remodeling, and wound healing. We made an exhaustive review of the use of PRP in chronic tendinopathies: epicondylitis, rotator cuff, patellar and calcaneal tendinopathies, and plantar fasciitis. Medline, Embase and Google Scholar were used (until July 31, 2012). Clinical studies about PRP and tendinopathies (in English and French language peer-reviewed journals) were included. Articles with a high level of evidence were considered preferentially. Despite the proven efficacy of PRP on tissue regeneration in experimental studies, there is currently scanty tangible clinical evidence with respect to chronic tendon disorders. The few studies that have been performed appear unlikely to be comparable. Randomized controlled studies with appropriate placebo groups are needed to determine the real effectiveness of PRP for treating chronic musculoskeletal injuries. [less ▲]

Introduction: The treatment of choice for tendinopathies is eccentric reeducation. Although the clinical results appear favourable, the biomechanical changes to the tissue are not yet clear. Even if the mechanotransduction theory is commonly accepted, the physiology of tendons is not clearly understood. We aimed to better define the biomechanical and histological changes that affect healthy tendon after eccentric and concentric training. Materiel and Methods: This study compared the effects of 2 methods of training (eccentric (E) training and concentric (C) training) with untrained (U) rats. The animals were trained over a period of 5 weeks. The tricipital, patellar and Achilles tendons were removed, measured and a tensile test until failure was performed. A histological analysis (hematoxylin and eosin and Masson's trichrome stains) was also realized. Results: There was a significant increase in the rupture force of the patellar and tricipital tendons between the U and E groups. The tricipital tendons in the control group presented a significantly smaller cross-sectional area than the E- and C-trained groups, but none was constated between E and C groups. No significant difference was observed for the mechanical stress between the three groups for all three tendons. Histological studies demonstrated the development of a greater number of blood vessels and a larger quantity of collagen in the E group. Discussion and conclusion: The mechanical properties of tendons in rats improve after specific training, especially following eccentric training. Our results partly explained how mechanical loading, especially in eccentric mode, could improve the healing of tendon. [less ▲]
