Platelet-rich plasma (PRP) contains a large quantity of growth factors, which may enhance tendon 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. We reported a case of exuberant inflammatory reaction after one infiltration of PRP to treat jumper’s knee in a type 1 diabetic patient who was 35 years old. Injections of PRP must be proposed after careful consideration for patients with morbidity risks linked to insulin-dependent diabetes. [less ▲]

Les traitements «passifs» des tendinopathies sont généralement utilisés de manière empirique pour combattre la douleur mais ne modifient pas la structure histologique du tendon. Par contre, le travail excentrique a pour but de contrecarrer une théorie étiopathogénique proposant une insuffisance de résistance du tendon exposé à des charges externes qui peuvent progressivement entrainer des lésions. Les résultats cliniques suite à cette prise en charge montrent souvent une évolution favorable des douleurs. Les ondes de choc extra-corporelles demeurent une option thérapeutique non-invasives et présentent peu de complications. De plus, elles sont employées avec succès pour traiter des tendinopathies chroniques rebelles aux traitements conservateurs classiques. Le plasma riche en plaquettes (PRP) est obtenu par centrifugation de sang autologue afin d’obtenir une grande concentration plaquettaire dépendant de la technique employée. Malgré la preuve de l’efficacité du PRP sur la régénération tissulaire en laboratoire, il existe actuellement peu de preuves cliniques tangibles concernant le traitement des tendinopathies chroniques. Enfin, d’autres nouvelles options thérapeutiques (patches de dérivés nitrés, infiltrations de polidocanol, d’acide hyaluronique et de cellules souches) sont également abordées. [less ▲]

Tendon lesions are among the most frequent musculoskeletal pathologies. Vascular endothelial growth factor (VEGF) is known to regulate angiogenesis. VEGF-111, a biologically active and proteolysis-resistant splice variant of this family, was recently identified. This study aimed at evaluating whether VEGF-111 could have a therapeutic interest in tendon pathologies. Surgical section of one Achilles tendon of rats was performed before a local injection of either saline or VEGF-111. After 5, 15 and 30 days, the Achilles tendons of 10 rats of both groups were sampled and submitted to a biomechanical tensile test. The force necessary to induce tendon rupture was greater for tendons of the VEGF-111 group (p<0.05) while the section areas of the tendons were similar. The mechanical stress was similar at 5 and 15 days in the both groups but was improved for the VEGF-111 group at day 30 (p <0.001). No difference was observed in the mRNA expression of collagen III, tenomodulin and MMP-9. In conclusion, we observed that a local injection of VEGF-111 improves the early phases of the healing process of rat tendons after a surgical section. Further confirmatory experimentations are needed to consolidate our results. [less ▲]

Introduction: Different series emphasized the necessity of rehabilitation program after infiltration of platelet-rich plasma (PRP) in case of tendinopathy. However, most of them describe only briefly the reeducation protocol and these programs vary. Our aim was to extensively describe a specific standardized rehabilitation program. Methods: After a review of literature of post-PRP infiltration protocols, we had developed a standardized rehabilitation protocol. This protocol was evaluated by 30 subjects with chronic jumper’s knee who. A a standardised progressive sub-maximal eccentric program supervised by a physical therapist for 6 weeks was started 1 week post-infiltration. The patient benefited also from electromyostimulation, isometric strengthening and stretching of the quadriceps, cycloergometer and cryotherapy. After the supervised program, the patient had to make an auto-reeducation added to the reathletisation protocol for 6 more weeks which was followed by maintenance exercises up to 1 year. The assessments were made using a VAS, IKDC and VISA-P scores. Results: The VAS , IKDC and VISA-P scores decreased very significantly with time. The compliance to auto-reeducation was good. Conclusion: We proposed a simple and efficient protocol based on sub-maximal eccentric reeducation to add to PRP infiltrations in case of patellar tendinopathy. [less ▲]

We report the case of a patient presenting with an akineto-rigid syndrome of the left hemibody whose etiological exploration by magnetic resonance imaging showed the presence of a cavernoma located in the right lenticular region. The interest of this situation lies in establishing whether pathophysiological link may exist between such symptoms and the lesion. [less ▲]

“Conventional” treatments of tendinopathies are generally employed empirically to fight pain and inflammation but they do not modify the histological structure of the tendon. However, these treatments are not completely satisfactory and the recurrence of symptoms is common. In contrast to the passive pattern of many therapies dedicated to tendon disorders, some authors have promoted an eccentric training mode. Such active eccentric training programs are aimed at thwarting an aetiopathogenic theory proposing insufficient tensile strength of the tendon exposed to external loads which could progressively damage it. Though the literature remains incomplete on tendon architecture remodelling and real histological adaptations following an adapted eccentric training, clinical results following such therapy appear promising. Due to its noninvasiveness, low complication rate and high applicability combined with good results, extracorporeal shock wave therapy has become a well known option within the therapeutic spectrum for many tendinopathies. More specifically, it has been successfully applied in chronic tendinopathy resistant to a conservative training program including eccentric exercises. Platelets release different cytokines and growth factors that could promote angiogenesis, tissue remodelling (bone, skin etc.), and wound healing. Platelet-rich plasma (PRP) is obtained by centrifuging autologous blood to have a high concentration of platelets depending on the isolation method. For this reason, different PRP preparation techniques cannot provide a consistently identical final product, but there is currently no international consensus on this issue. Despite the proven efficacy of PRP tissue regeneration in labs, there is currently little tangible clinical evidence for chronic tendon disorders. The few studies that have been performed appear unlikely to be comparable. Up to now, randomised controlled studies with appropriate placebo groups are needed to determine the real effectiveness of PRP for treating chronic tendon conditions. However, this therapeutic option remains very popular in sports, and many top athletes are using it in case of musculoskeletal conditions. What is more, it has been removed from the doping lost of the World AntiDoping Agency. Other new therapeutic options (infiltrations of polidocanol, hyaluronic acid, botulinum toxin, patches of derivatives Nitro...) for treating tendinopathies are also discussed in this review.

Introduction : Infiltrations of plasma rich platelets (PRP) represent a new treatment of tendinopathies. Currently, no side effects were reported in this indication. Case report: We report the case of a 35-year-old type 1 diabetic patient with right upper patellar tendinopathy that had persisted for more than 6 months. The patient benefited from an intratendinous infiltration of 6 mL of PRP (8.105 platelets/mm3, almost no red or white blood cells) after a carefully disinfection but without local anesthesia. Typically, a standardized program of sub-maximal eccentric rehabilitation should be started 1 week after infiltration. However, the patient experienced local swelling with erythema, increased heating and pain, which appeared just underneath the patella, without biological inflammatory syndrome. In absence of septic general symptoms, no blood or wound culture were made. At 2 weeks post-infiltration, a greatly increased Doppler signal in a thicker tendon was observed by ultrasounds compared to that before infiltration, but there was no sign of infection demonstrated by either MRI or CT. However, the local inflammation did not decrease after a 3-week treatment of local cryotherapy, local and oral NSAID, and adjunct use of colchicine 1 mg. Thus, an insidious infection was suspected, even though there was no evidence of biological inflammatory syndrome or sign of infectious lesion on imagery examination. Antibiotic therapy (rifampicine 600 mg + minocycline 100 mg), was initiated for three months. Due to a lack of improvement via imaging and clinical examination, a 3-phase bone scintigraphy was performed. The results suggested the presence of a complex regional pain syndrome type 1. The patient benefited from classical physical therapy and concomitant pain killers. The evolution was favorable after 6 months of treatment. Discussion : Even though PRP infiltration represents a new and promising treatment for tendinopathy, more studies are needed both to verify its clinical efficacy. Moreover, implementing this innovative treatment requires caution because of potential adverse events. Thus, the balance between benefits and risks must be carefully evaluated before using this treatment, especially in patients with type 1 diabetes. [less ▲]

Objective: Jumper’s knee is a frequent chronic overuse syndrome of the upper part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. Infiltration of platelet-rich plasma (PRP) could be a new therapy for such chronic tendinopathies. Materiel and methods: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10-point Visual Analogic Scale, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA-P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a standardised sub-maximal eccentric reeducation. Results: Pain during daily activities significantly decreased with time (especially after 6 weeks and continued to a lesser extend up to 3 months). During functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. Discussion: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol is efficient to improve symptoms of chronic jumper’s knee in patients non-responsive to classical conservative treatments.
