RESUMEN
PURPOSE@#The study aims to compare the efficacy and safety of a new minimally invasive osteosynthesis technique with those of conventional open surgery for transverse patellar fractures.@*METHODS@#It was a retrospective study. Adult patients with closed transverse patellar fracture were included, and with open comminuted patellar fracture were excluded. These patients were divided into minimally invasive osteosynthesis technique (MIOT) group and open reduction and internal fixation (ORIF) group. Surgical time, frequency of intraoperative fluoroscopy, visual analogue scale score, flexion, extension, Lysholm knee score, infection, malreduction, implant migration and implant irritation in two groups were recorded and compared. Statistical analysis was performed by the SPSS software package (version 19). A p < 0.05 indicated statistical significance.@*RESULTS@#A total of 55 patients with transverse patellar fractures enrolled in this study, the minimally invasive technique was performed in 27 cases, and open reduction was performed in 28 cases. The surgical time in the ORIF group was shorter than that in the MIOT group (p = 0.033). The visual analogue scale scores in the MIOT group were significantly lower than those in the ORIF group only in the first month after surgery (p = 0.015). Flexion was restored faster in the MIOT group than that in the ORIF group at one month (p = 0.001) and three months (p = 0.015). Extension was recovered faster in the MIOT group than that in the ORIF group at one month (p = 0.031) and three months (p = 0.023). The recorded Lysholm knee scores in the MIOT group were always greater than those in the ORIF group. Complications, such as infection, malreduction, implant migration, and implant irritation, occurred more frequently in the ORIF group.@*CONCLUSION@#Compared with the ORIF group, the MIOT group reduced postoperative pain and had less complications and better exercise rehabilitation. Although it requires a long operation time, MIOT may be a wise choice for transverse patellar fractures.

External snapping hip(ESH) is a vague term used to describe palpable or auditory snapping with hip movements with or without pain. The pathogenesis of ESH is related to the specific anatomical structure and friction factor. The clinical symptom is auditory snapping during activities, physical examination, X-ray, magnetic resonance imaging(MRI), dynamic ultrasound and other imaging techniques can be used to diagnose. Conservative medical management includes rest, avoidance of aggravating activities, and antiinflammatory medications. Treatment Patients with mild symptoms can achieve good results by medication, rest and physiotherapy. Surgical treatment for patients with ineffective conservative treatment was performed. All kinds of open surgery method can achieve good clinical curative effect, arthroscopic surgery is gradually been promoted due to small trauma, less complications. Besides, there are some reports that traditional treatments such as massage, acupuncture and acupotomology have achieved good clinical results, which deserve further study and promotion.
