ObjectivesTo evaluate the clinical and functional results of patients diagnosed with full-thickness chondral defects on symptomatic knees who underwent a biological repair technique using autologous matrix-induced chondrogenesis.MethodsSeven patients who underwent surgical treatment due to chondral lesions in the knee by autologous matrix-induced chondrogenesis were evaluated. The Lysholm, Kujala and visual analog scale of pain questionnaires were applied before and 12 months after the surgery. Nuclear magnetic resonance images were evaluated 12 months after surgery according to MOCART (magnetic resonance observation of cartilage repair tissue) cartilage repair tissue score.ResultsOf the seven patients evaluated, three presented defects classified as grade III and four as grade IV according to the International Cartilage Repair Society classification. Chondral defects were located in the medial femoral condyle (n = 2), patella (n = 2), and trochlea (n = 3). The mean age of the patients (six men and one woman) was 37.2 years (24–54 years). The mean chondral defect size was 2.11 cm2 (1.0–4.6 cm2). After 12 months, post-operative nuclear magnetic resonance showed resurfacing of the lesion site with scar tissue less thick than normal cartilage in all patients. The mean MOCART score was 66.42 points. A significant decrease in pain and an improvement in the Lysholm and Kujala scores were observed.ConclusionThe use of the collagen I/III porcine membrane was favorable for the treatment of chondral and osteochondral lesions of the knee when assessing the results using the VAS, Lysholm, and Kujala scores 1 year after surgery, as well as when assessing the magnetic resonance image of the lesion 6 months after surgery.

Objective:To evaluate the prevalence of joint hypermobility in patients undergoing knee surgery to treat traumatic injury to the meniscus and anterior cruciate ligament, and the influence of this hypermobility on postoperative results. Methods:This prospective study assessed joint hypermobility in patients who underwent surgical reconstruction of the anterior cruciate ligament (ACL), partial meniscectomy, or a procedure combining ACL reconstruction and partial meniscectomy during the period 2011-2015. The Beighton score was used to evaluate joint hypermobility and Tegner activity scale for postoperative assessment. Results:A total of 242 patients underwent surgery during the study period: 107 to treat ACL injuries, 75 to treat ACL injuries associated with meniscus injuries, and 60 to treat meniscus injuries. Of the total, 45 patients had joint hypermobility. We found no association between joint hypermobility and sex or type of injury. Postoperative Tegner scale results were not influenced by the presence of joint hypermobility. Conclusion:No association was found between joint hypermobility and the evaluated variables (gender and type of specific injury), and hypermobility did not have a negative impact on postoperative outcomes. Level of Evidence IV; Case series.

Objective: To evaluate the fellow in knee surgery and the training offered by accredited programs in Brazil. Methods: This cross-sectional study administered a questionnaire to fellows in knee surgery. Results: Most fellows reported being assisted by the preceptor in theoretical, practical, and scientific activities. Conclusion: The training offered by accredited programs to fellows in knee surgery presented good results for their education. This study may propose educational measures for the Brazilian Society for Surgery of the Knee (SBCJ). Level of Evidence IIC, Cross-sectional study.
