RESUMEN
BACKGROUND: To analyse the prevalences of the cam and pincer morphologies in a cohort of patients with groin pain syndrome caused by inguinal pathologies. MATERIALS AND METHODS: Forty-four patients (40 men and 4 women) who suffered from groin pain syndrome were enrolled in the study. All the patients were radiographically and clinically evaluated following a standardised protocol established by the First Groin Pain Syndrome Italian Consensus Conference on Terminology, Clinical Evaluation and Imaging Assessment in Groin Pain in Athlete. Subsequently, all of the subjects underwent a laparoscopic repair of the posterior inguinal wall. RESULTS: The study demonstrated an association between the cam morphology and inguinal pathologies in 88.6% of the cases (39 subjects). This relationship may be explained by noting that the cam morphology leads to biomechanical stress at the posterior inguinal wall level. CONCLUSIONS: Athletic subjects who present the cam morphology may be considered a population at risk of developing inguinal pathologies. LEVEL OF EVIDENCE: Level IV, Observational cross-sectional study.

PURPOSE: The aim of the study was to evaluate, in a group of adolescents, the onset of varus-valgus deviations in the sagittal plane after performing a trans-tibial trans-epiphyseal technique of ACL reconstruction with a follow-up of at least 2 years. METHODS: Seventy-one patients aged 12-15 years old (Tanner scale 3 and 4) have undergone ACL reconstruction with STG using arthroscopy. All patients were evaluated clinically using the visual analogue scale (VAS), the Lysholm score and the Tegner activity score at the time of surgery. All patients were reevaluated after a follow-up period of at least 2 years (T1) using the VAS, the Lysholm score, the Tegner activity score and radiographic studies in order to compare the operated limb with the healthy control limb. RESULTS: Valgus difference exceeding 2° in the knee axis between the operated limb and the healthy control limb was observed only in three patients (4.2%: 95% CI 0.88-11.86%). The average difference was <1° (0.3°, 95% CI 0.0-0.55). CONCLUSION: The trans-tibial trans-epiphyseal technique of ACL reconstruction, according to the results obtained, seems to be a valid alternative procedure, when performed by a skilled orthopaedic surgeon, offering an excellent safety profile and at the same time very good clinical results. LEVEL OF EVIDENCE: IV.

PURPOSE: The influence of patient-specific instrumentations on the accuracy of unicompartmental medial knee replacement remains unclear. The goal of this study was to examine the ability of patient-specific instrumentation to accurately reproduce postoperatively what the surgeon had planned preoperatively. METHODS: Twenty consecutive patients (20 knees) who suffered from isolated unicompartmental medial osteoarthritis of the knee and underwent medial knee replacement using newly introduced magnetic resonance imaging-based patient-specific instrumentation were assessed. This assessment recorded the following parameters: (1) the planned and the postoperative mechanical axis acquired through long-leg AP view radiographies; (2) the planned and the postoperative tibial slope acquired by means of standard AP and lateral view radiographies; and (3) the postoperative fit of the implanted components to the bone in coronal and sagittal planes. The hypothesis of the study was that there was no statistically significant difference between postoperative results and preoperatively planned values. RESULTS: The study showed that (1) the difference between the postoperative mechanical axis (mean 1.9° varus ± 1.2° SD) and the planned mechanical axis (mean 1.8° varus ± 1.2° SD) was not statistically significant; (2) the difference between the postoperative tibial slope (mean 5.2° ± 0.6° SD) and the planned tibial slope (mean 5.4° ± 0.6° SD) was statistically significant (p = 0.008); and (3) the postoperative component fit to bone in the coronal and sagittal planes was accurate in all cases; nevertheless, in one knee, all components were implanted one size smaller than preoperatively planned. Moreover, in two additional cases, one size thinner and one size thicker of the polyethylene insert were used. CONCLUSIONS: This study suggests that overall patient-specific instrumentation was highly accurate in reproducing postoperatively what the surgeon had planned preoperatively in terms of mechanical axis, tibial slope and component fit to bone.

PURPOSE: Healing rate of meniscus repair is higher when the suture is associated with anterior cruciate ligament reconstruction. A possible explanation can be a different pattern of release of growth factors between anterior cruciate ligament reconstruction and isolated meniscus surgery. Hypothesis of this study is that the concentrations of bFGF, TGF-ß and platelet-derived growth factor (PDGF) in joint fluid, immediately after single-bundle anterior cruciate ligament reconstruction and arthroscopic partial meniscectomy, can be different. METHODS: Twenty consecutive patients underwent partial medial meniscectomy and twenty consecutive patients underwent single-bundle anterior cruciate ligament reconstruction with hamstring grafts were enrolled in the study. Thirty minutes after the end of the surgical procedure, a sample of joint fluid, as well of venous blood, was collected from all the patients. Concentrations of growth factors were determined by enzyme-linked immunosorbent assay. RESULTS: The peripheral blood concentration of TGF-ß, bFGF and PDGF was comparable between partial meniscectomy and anterior cruciate ligament reconstruction groups. No differences between the two surgical techniques were also found in term of TGF-ß and bFGF joint fluid concentration, whereas joint PDGF concentration of anterior cruciate ligament reconstruction patients was significantly higher than the one found in partial meniscectomy patients. CONCLUSIONS: A significant growth factors release was detected in the knee joint during arthroscopic surgery. PDGF concentration was significantly higher in anterior cruciate ligament reconstructed knee than in the meniscectomy group. PDGF can play an important role enhancing the healing response of meniscus suture and can be one of the biological reasons of the higher meniscal healing rate in anterior cruciate ligament reconstructed knee.

PURPOSE: Autologous collagen-induced chondrogenesis technique (ACIC) combines microfractures with the use of an injectable atelocollagen matrix that allows performing the whole cartilage repair treatment arthroscopically. The aim of this study was to evaluate the in vitro cytocompatibility of this biomaterial using human bone marrow mesenchymal stem cells and human chondrocytes. Moreover, the preliminary data of five patients affected by chondral lesion of the talus treated with the ACIC technique are shown. METHODS: Human bone marrow mesenchymal stem cells and human chondrocytes were seeded on solid and pre-solid atelocollagen scaffolds. Cell-scaffold constructs were cultured for 7 days and then prepared for histological analyses. Arthroscopic ACIC was performed in five patients affected by chondral lesions of the talus; they were clinically evaluated with AOFAS, VAS and Tegner score before and then after 6 months from surgery. RESULTS: In vitro results showed that both bone marrow mesenchymal stem cells and chondrocytes were able to efficiently colonize the whole construct, from the surface to the core, only when seeded on the pre-solid atelocollagen scaffold, but not on its solid form. No adverse events were observed in the patients treated with the ACIC technique; a significant improvement in VAS pain scale and in AOFAS score was found at 6 months follow up. CONCLUSION: Injectable atelocollagen can be considered a feasible scaffold for cartilage repair treatment, in particular if used in its pre-solid form. ACIC leads to good clinical results in the treatment for chondral lesions of the talus even if longer follow-up and a higher number of patients are necessary to confirm these data.

INTRODUCTION: Autologous Matrix-Induced Chondrogenesis (AMIC) is an innovative treatment for localized full-thickness cartilage defects combining the well-known microfracturing with collagen I/III scaffold. The purpose of this analysis was to evaluate the medium-term results of this enhanced microfracture technique for the treatment of chondral lesions of the knee. METHODS AND MATERIALS: Patients treated with AMIC (Chondro-Gide, Geistlich Pharma, Switzerland) were followed using the AMIC Registry, an internet-based tool to longitudinally track changes in function and symptoms by the Lysholm score and VAS. RESULTS: A series of 57 patients was enrolled. The average age of patients (19 females, 38 males) was 37.3 years (range 17-61 years). The mean defect size of the chondral lesions was 3.4 cm(2) (range 1.0-12.0 cm(2)). All defects were classified as grade III (n = 20) or IV (n = 37) according to the Outerbridge classification. Defects were localized at the medial (n = 32) or lateral (n = 6) condyle, at the trochlea (n = 4) and at the patella (n = 15). The follow-up period was 2 years. The majority of patients were satisfied with the postoperative outcome, reporting a significant decrease of pain (mean VAS preop = 7.0; 1 year postop = 2.7; 2 years postop = 2.0). Significant improvement of the mean Lysholm score was observed as early as 1 year after AMIC and further increased values were noted up to 2 years postoperatively (preop. 50.1, 1 year postop. 79.9, 2 year postop. 85.2). CONCLUSIONS: AMIC is an effective and safe method of treating symptomatic chondral defects of the knee. However, further studies with long-term follow-up are needed to determine if the grafted area will maintain structural and functional integrity over time. LEVEL OF EVIDENCE: Prognostic study, Level IV.

PURPOSE: Bone-patellar tendon-bone technique (BPTB) for anterior cruciate ligament injuries is associated with a higher risk of donor-site morbidity. To evaluate whether platelet-rich plasma (PRP), due to its anti-inflammatory properties and capacity to stimulate tissue regeneration, was able to reduce the anterior knee pain, the kneeling pain, and donor-site morbidity, as evidenced by evaluation of VISA and VAS scoring scales and MRI analysis of the tendon and bone defect, we performed a clinical randomized controlled study where PRP gel was applied to donor site after ACL reconstruction with BPTB. METHODS: Forty young athletes with the indication of ACL reconstruction with patellar tendon grafts were randomly assigned to group A (n = 20 patients, control group) or group B (n = 20 patients, PRP group). The autologous PRP gel was applied to both the patellar and tendon bone plug harvest site and stabilized by the peritenon suture. At 12-month follow-up, all patients underwent clinical examination and VAS and VISA questionnaires, respectively, evaluating the average daily pain of the knee and the pain during particular activities involving the knee, were filled. MRI at the same time point was also performed. RESULTS: VISA scores were significantly higher in the patients treated with PRP (84.5 ± 11.8 and 97.8 ± 2.5 for group A and for group B; P = 0.041), whereas no significant difference in postoperative VAS scores between the two groups was observed (1 ± 1.4 and 0.6 ± 0.9 for group A and group B, n.s.). In 85% of PRP group patients, the tibial and patellar bone defect was satisfactorily filled by new bony tissue (>70% of bone gap filled), whereas this percentage was just of 60% in control group patients, but this difference was not statistically significant. CONCLUSIONS: The study shows the usefulness of PRP in reducing subjective pain at the donor-site level after ACL reconstruction with BPTB. However, this approach deserves further investigations to confirm PRP efficacy and to elucidate its mechanism of action. LEVEL OF EVIDENCE: Prospective randomized controlled study, Level I.

This paper presents a case report of a 27-year-old male patient affected by a large osteochondral defect of the medial femoral condyle (6 cm(2)) in a varus knee. He was treated with a combined approach consisting of high tibial osteotomy and autologous matrix-induced chondrogenesis technique enhanced by a bone marrow-enriched bone graft. Twelve months after surgery, the patient reported considerable reduction in pain and significant increase in his quality of life. A hyaline-like cartilage completely covered the defect and was congruent with the surrounding condyle cartilage as revealed by MRI and by a second-look arthroscopy. Level of evidence IV.

Various factors may account for the positive association between meniscal repair and anterior cruciate ligament reconstruction, one being the modulation of healing response of meniscal fibrochondrocytes by growth factors released with intra-articular bleeding and fibrin clot formation. Analysis of vascular endothelial growth factor (VEGF) and its receptors, VEGFR1 and VEGFR2, may be useful in the clinical assessment of bone and soft-tissue remodeling. We measured systemic and local levels of VEGF (VEGF165), VEGFR1 and VEGFR2 after either arthroscopic partial meniscectomy (APM) or single-bundle anterior cruciate ligament reconstruction (ACLR) in order to determine the local effect of bone tunnelling and notchplasty on the release of these growth factors. The study population included 40 patients: 20 consecutive patients had undergone ACLR with hamstring grafts and 20 had undergone APM. Thirty minutes after the end of the operation, knee joint fluid samples were collected via the drainage tube and at the same time venous blood samples were drawn. In both sets of samples, VEGF, VEGFR1 and VEGFR2 concentrations were determined by enzyme-linked immunosorbent assay (ELISA). No significant differences in VEGF, VEGFR1 or VEGFR2 concentrations in the venous blood were observed between the two treatment groups. In contrast, VEGF and VEGFR2 levels were significantly higher in the knee joint fluid of the ACLR group; furthermore, VEGF and VEGFR1 were significantly higher in the knee joint fluid than in the venous blood, whereas VEGFR2 was lower in the knee joint fluid than in the venous blood. Local release of VEGF and its angiogenetic receptor VEGFR2, but not the negative regulator VEGFR1, was significantly higher after ACLR than after APM, indicating a better vasculogenic potential for enhanced bone-graft and meniscus healing. These results could suggest that VEGF and VEGFRs could be considered as good biomarkers of tissue healing after knee joint surgery.

AIM: The efficacy of PRP in the treatment of tendinopathies has been already studied both in in vitro and in clinical studies. This paper describes the local and the systemic effects of US-guided autologous PRP (Platelet Rich Plasma) injections in chronic tendinopathies in sportspersons. METHODS: Fifteen patients (13 male, 2 female) between 17 and 68 years old, affected by chronic tendinopathies at different sites were treated with an echographically guided injection of autologous PRP within the pathological area of the tendons. VISA score and MRI data were collected pre interventions and after 90 days and 24 months from treatment. Changes in different inteleukins (ILs), tumour necrosis factor α (TNF α), interferon γ, vascular endothelial growth factor (VEGF), endothelial growth factor (EGF), chemokine (C-C motif) ligand 2 (CCL2), were analysed at four time points in the peripheral blood of five patients. RESULTS: After 90 days the VISA score significantly improved from 36±12 (range 21-64) to 74±17 (range 40-92). Reduction of irregularities was found in 80% of the tendons. After 24 months patients reported an average VISA score of 73±16 (range 42-100). No changes in IL, TNF α and interferon γ were observed. VEGF, EGF and CCL2 decreased progressively from 30m to 3 h after the treatment and returned to near the baselines after 24 h. CONCLUSION: PRP injection allow an improvement of the clinical symptomatology, which is well maintained at least for two years from treatment. The PRP-based local therapy could influence systems homeostasis and antidoping evaluations, but, in our opinion, it doesn't represent a doping substance in itself.

Growth factors (GFs) act as signalling agents for cells and become a more and more popular mean to influence the human body and its tissues. This review gives an overview of the current possibilities to use such agents in the field of sports related injuries and thus providing the athlete with a whole new potential to minimize recovery time. GFs and its application have been studied intensively for a long time starting with animal studies. For some of this GFs this research has been brought onto the next level to clinical phase trials. Agents such as insulin like growth factor 1 (IGF-1), mechano growth factor (MGF), basic fibroblast growth factor (B-FGF), platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor b (TGF-b), bone morphogenetic protein (BMP) and leukemia inhibitory factor (LIF) are being discussed in this review. These GFs not only have the potential to be used to cure injuries but also are being in the centre of interest for doping abusers and are a powerful yet not fully understood technique to gain performance.

The nomenclature and the lack of consensus of clinical evaluation and imaging assessment in groin pain generate significant confusion in this field. The Groin Pain Syndrome Italian Consensus Conference has been organised in order to prepare a consensus document regarding taxonomy, clinical evaluation and imaging assessment for groin pain. A 1-day Consensus Conference was organised on 5 February 2016, in Milan (Italy). 41 Italian experts with different backgrounds participated in the discussion. A consensus document previously drafted was discussed, eventually modified, and finally approved by all members of the Consensus Conference. Unanimous consensus was reached concerning: (1) taxonomy (2) clinical evaluation and (3) imaging assessment. The synthesis of these 3 points is included in this paper. The Groin Pain Syndrome Italian Consensus Conference reached a consensus on three main points concerning the groin pain syndrome assessment, in an attempt to clarify this challenging medical problem.
RESUMEN
Patients with sports injuries were treated with pirprofen, a non-steroidal anti-inflammatory drug, in two separate studies. In the single centre study, 39 athletes were treated with 1000 mg/day pirprofen for 2 weeks. In the multicentre study, a further 80 athletes were treated with a variable dosage (600-1200 mg/day) until the disappearance of symptoms, but for no longer than 2 weeks. Efficacy was considered excellent or good in 99/119 (83%) of the patients treated. The clinical variables of pain and mobility significantly (P less than 0.05) improved after 1 week of treatment. Tolerability was satisfactory, the main side-effects involving the gastro-intestinal tract.

Meniscal allograft transplantation has emerged as a useful treatment for carefully selected patients. The aim of this review of meniscal allograft transplantation is to put this procedure into a clinical perspective. Since there still is a lack of consensus on how the success of meniscal transplantation should be evaluated it is difficult to compare study outcomes. Nevertheless, almost all studies report an increase in patient satisfaction and improvement in pain and function. Clinical and functional outcome is improved in the majority of patients. Progression of cartilage degeneration according to MRI and radiological criteria was halted in a number of patients, indicating a chondroprotective effect. Joint space narrowing is only significantly progressive at long-term follow-up. On magnetic resonance imaging, shrinkage is seen after some years, but more in lyophilized allografts. Second-look arthroscopy usually shows good healing to the capsule. Overall, the clinical results of this type of surgery are encouraging and long-lasting in a well selected patient population who suffered a total meniscectomy. Meniscal allografting appears to becoming the golden standard therapy for these type of patients.

Tendon and ligament injures cause significant loss of performance in sport and decreased functional capacity in the workplace. Many of these injures remain difficult to treat, and many individuals have long-term pain and discomfort. Animal studies of growth factor and cell-based therapies have shown promising results, but these treatments also can be misused to enhance athletic performance. The International Olympic Committee (IOC) now has high-level scientific advisors who can advise the IOC as to the use and abuse of these technologies.

For 4 years we followed a group of football players in the youth division of a professional club, ranging in age from 9 to 19 years, and analyzed the major injuries, i.e., those which required them to be sidelined for at least 4 weeks. We observed 23 sprains, 16 fractures, 16 cases of osteochondrosis, 7 muscle lesions, 6 cases of groin pain (athletic pubalgia), and 4 tendonopathies. The most frequent sites were the knee (n=30) and the ankle (n=11); the trauma factor was predominant (65.2%) with respect to overuse; noncontact traumas were more numerous (63.8%) than those resulting from contrast. Of a total 72 cases 8 regarded goalkeepers, and the remaining 64 cases were distributed among the other positions. As regards the age categories we detected a prevalence of osteochondrosis, traumatic detachments, and some fractures in the younger players, while in the older athletes we observed more sprains, muscle lesions, and tendonopathies.

To evaluate the effects of a rehabilitation brace locked in extension for the first week on the recovery of full extension after ACL reconstruction we compared two groups of subjects who underwent ACL bone-patellar tendon-bone reconstruction. The brace was unlocked twice a day for assisted physiotherapy. In Group A, 18 male subjects wore a post-operative brace locked from 0 degrees to 90 degrees. In Group B, 18 male subjects wore the same post-op brace locked in full extension for the first week. In both groups the brace was unlocked (0 degrees -120 degrees ) at the beginning of the second postoperative week, and then removed at the beginning of the third week. All the subjects followed the same rigorous, accelerated rehabilitation protocol. Each subject was evaluated pre and post-operatively (at second, fourth and eighth week) with bubble-level heel height difference (HHD) measurements and KT 1000 arthrometric assessment at the fourth postoperative month. Preoperative bubble-level HHD measurements of the two groups were statistically similar (Group A 0.6 cm, Group B 1 cm; not significant, n.s.). At the fourth week (Group A 2.2 cm, Group B 0.6 cm) and eighth week (Group A 1.6 cm, Group B 0.1 cm) follow-ups, bubble-level HHD measurements showed that the extension of the operated knees of Group B was significantly greater than in Group A. KT 1000 arthrometric scores showed no difference between the two groups (Group A 1.8 mm, Group B 1.5; n.s.).
