RESUMEN
OBJECTIVE: Misdiagnosed/chronic Achilles tendon injuries are rare and disabling for patients. The surgical treatment of these rare injuries aims to ensure the tendon heals mechanically and biologically. This is the prerequisite for a good clinical and functional outcome and reduces recurrences. The main aim of the study is to present a surgical technique that has proven to be original, reproducible, and capable of guaranteeing solid tendon repair and optimal tissue regeneration. METHODS: We treated five patients, four males and one female, with the one-step double augmentation technique. All patients of this study complained of pain, but above all severe functional limitation that Achilles tendon injury had been causing for more than a month. In this study, we widely described the surgical technique, original and not found in the literature, which provides a biological graft (allograft of decellularized dermis) and homologous, thrombin-activated, platelet-rich plasma (H-PRP) in a single step. Surgical approach, always used by the first author, respected predefined steps: careful dissection and preparation of the peritendinous tissues from suture to the end of the procedure, tenorrhaphy, and augmentation with allopatch to obtain a mechanically effective repair to avoid recurrences, and finally "biological" augmentation with a unit of homologous, thrombin activated, PRP. We offered to all patients a regenerative rehabilitation program post-operatively. RESULTS: All patients were evaluated clinically (functional clinical tests and questionnaires) and instrumentally (elastic-sonography and perfusion MRI). The obtained results have been evaluated at a minimum follow-up of 18 months and a maximum of 24 months. In all patients pain was resolved, and district function and kinetic chains improved with resumption of daily activities, work, and sports. CONCLUSION: The present study confirmed the regenerative potential of decellularized dermis allograft and PRP (homologous and thrombin-activated). The same approach can also be exploited in cases of severe tendon destructuring and limited "intrinsic" regenerative potential at any age. The proposed one-step surgical technique of a double augmentation therefore appears useful, safe, reproducible, and applicable in all chronic tendon lesions with low regenerative potential.

OBJECTIVE: To assess the effects of postural rehabilitation (PR) on trunk asymmetry and balance, with and without Kinesio taping (KT) of the back muscles as additional treatment, in patients with Parkinson's disease (PD) who have postural disorders. DESIGN: Single-blind, randomized controlled trial with 1-month follow-up. SETTING: Ambulatory care in referral center. PARTICIPANTS: Patients (N=20) with PD showing postural abnormalities of the trunk, in the sagittal and/or coronal plane. INTERVENTIONS: Four weeks of patient-tailored proprioceptive and tactile stimulation, combined with stretching and postural reeducation, was provided to 13 subjects (PR group), while 7 received no treatment (control group). Six of the 13 subjects receiving PR also had KT strips applied to their trunk muscles, according to the features of their postural abnormalities. MAIN OUTCOME MEASURES: Berg Balance Scale, Timed Up and Go, and degrees of trunk bending in the sagittal and coronal planes were assessed at the enrollment (t0), 1 month later (t1), and 2 months later (t2). RESULTS: At t1, all treated patients showed a significant improvement in trunk posture in both the sagittal (P=.002) and coronal planes (P=.01), compared with baseline. Moreover, they showed an improvement in measures of gait and balance (P<.01). Benefits persisted at t2 for all measures, except lateral trunk bend. No differences were found when comparing the PR and KT groups. CONCLUSIONS: The combination of active posture correction and trunk movements, muscle stretching, and proprioceptive stimulation may usefully impact PD axial symptoms. Repeated training is advocated to avoid waning of the effect.

BACKGROUND: Among the various complications described in literature, the patellar tendon ossification is an uncommon occurrence in anterior cruciate ligament (ACL) reconstruction using bone - patellar tendon - bone graft (BPTB). The heterotopic ossification is linked to knee traumatism, intramedullary nailing of the tibia and after partial patellectomy, but only two cases of this event linked to ACL surgery have been reported in literature. CASE PRESENTATION: We present a case of a 42-year-old Caucasian man affected by symptomatic extended heterotopic ossification of patellar tendon after 20 months from ACL reconstruction using BPTB. The clinical diagnosis was confirmed by Ultrasound, X-Ray and Computed Tomography studies, blood tests were performed to exclude metabolic diseases then the surgical removal of the lesion was performed. After three years from surgery, the patient did not report femoro-patellar pain, there was not range of motion limitation and the clinical-radiological examinations resulted negative. CONCLUSION: The surgical removal of the ossifications followed by anti-inflammatory therapy, seems to be useful in order to relieve pain and to prevent relapses. Moreover, a thorough cleaning of the patellar tendon may reveal useful, in order to prevent bone fragments remain inside it and to reduce patellar tendon heterotopic ossification risk.

PURPOSE: The purpose of this study was to evaluate the efficacy of platelet-rich plasma (PRP) in reducing femoral and tibial tunnel enlargement in patients operated on for anterior cruciate ligament reconstruction with hamstrings. METHODS: Forty male patients, in which both femoral and tibial 9-mm tunnels were performed because of the graft size, were enrolled in this prospective study. They were randomly assigned to group A (20 patients, PRP group) and group B (20 patients, control group). All patients were followed up at a median of 14.7 months (range 10-16 months), with a physical examination, the Tegner, Lysholm and objective IKDC scoring scales, and with the KT-1000 arthrometer. Moreover, they underwent a CT evaluation in order to assess the amount of tunnel enlargement. RESULTS: Femoral tunnel diameter increased from 9.0 ± 0.1 mm to 9.8 ± 0.3 mm in group A (p = 0.032) and from 9.0 ± 0.1 mm to 9.4 ± 0.5 mm in group B (p = 0.043). Tibial tunnel diameter increased from 9.0 ± 0.2 mm to 10.9 ± 0.2 mm in group A (p = 0.029) and from 9.1 ± 0.1 mm to 10.1 ± 0.4 mm in group B (p = 0.028). Physical examination as well as the evaluation scales used showed no differences between the two groups. CONCLUSIONS: The use of PRP does not seem to be effective in preventing tunnel enlargement.

Tenosynovial giant cell tumors originate from the synovial tissue of the joints, tendon sheaths, mucosal bursas, and fibrous tissues adjacent to tendons. The disease presents in localized and diffused forms. Large joints, such as the knee, are not frequently affected. Magnetic resonance imaging has been reported to be the best noninvasive technique to diagnose these tumors. Magnetic resonance imaging diagnosis has to be confirmed by histopathological examination. Few reports exist of tenosynovial giant cell tumors arising from the posterior cruciate ligament. This article describes a case of an 18-year-old man with no history of trauma but with a 2-year history of mild, ongoing, and worsening right knee pain and swelling localized in the popliteal region. Clinical examination of the knee was negative. Magnetic resonance imaging revealed an intra-articular mass measuring 4.8×2.1×2.7 cm in the posterior region of the knee attached to the posterior cruciate ligament. Arthroscopy was performed using the posterior approach through the posterolateral and posteromedial portals. A specimen of the lesion was removed arthroscopically for histopathological examination, and a wide resection of the mass was performed with a shaver and a radiofrequency ablation device. Histopathological examination confirmed the diagnosis of a tenosynovial giant cell tumor. No recurrence had occurred at 2-year follow-up. Magnetic resonance imaging and histopathological examination may help in achieving a correct diagnosis, and arthroscopic excision using a posterior approach may be the treatment of choice by surgeons.
