[Ab] Abstract:OBJECTIVE: To discuss the surgical methods of total knee arthroplasty (TKA) in the patients with active tuberculosis of the knee and find out its curative effect after TKA. PATIENTS AND METHODS: We analyzed 10 patients with active tuberculosis of the knee who received TKA in our department from March 2006 to March 2010, whose ages were from 22 to 64 years old (average age was 40.6 ± 1 years). The following parameters were measured in the pre- and post-operation periods: HSS score, range of motion (ROM). From x-ray to find out post-operate curative effect of TKA. RESULTS: All cases had pain and elevated ESR. Deep vein thrombosis (DVT) and nerve damage were not found in these cases. There were 4 cases that had sinuses on the skin: the skin healed before the operation took place. Pre-operation HSS average scores were 25.0 ± 2. All patients received TKA by the para-patellar medial approach. Eight cases were followed-up for 6-28 months; the average follow-up period was 14 ± 0.5 months. Post-operation we took an HSS score and X-rays to find out its curative effect after TKA operation. There were also no patients with dislocation, aseptic loosening or fracture of prosthesis, although 1 case had recurrence. Post-operation's HSS average scores were 86.75 ± 5.45. The average ROM was improved to 95 ± 5°. CONCLUSIONS: Recent clinical results indicate that TKA is effective to treat the patients with active tuberculosis of the knee joint. TKA can significantly improve the function of the joint and relieve pain, improving patients' living conditions.

[Ab] Abstract:INTRODUCTION: Among the numerous techniques available, medial patellofemoral ligament (MPFL) reconstruction is increasingly used for the surgical treatment of objective patellar instability. The main objective of the present study was to assess efficacy in preventing recurrence of patellar dislocation and in correcting radiographic patellar tilt. The study hypothesis was that MPFL reconstruction, isolated or with associated bone surgery, by restoring "favorable" graft anisometry, provides a good trade-off between patellar stability and absence of postoperative stiffness. MATERIALS AND METHODS: Eighty-seven patients (90 reconstructions) presenting with objective patellar instability were prospectively included. The standardized procedure comprised MPFL reconstruction using the gracilis tendon. Femoral fixation used an interference screw in a blind tunnel between the adductor magnus tubercle and the medial epicondyle; patellar fixation used 2 anchors. Complementary distal bone graft was associated in 21 patients due to a preoperative tibial tubercle-trochlear groove (TT-TG) distance exceeding 20mm or to patella alta. Functional IKDC and Kujala scores and radiographic measurement of patellar tilt and femoral tunnel position were assessed preoperatively and at end of follow-up. RESULTS: Mean follow-up was 24.3months (range, 6-49months). Three patients showed recurrence of patellar dislocation. Mean Kujala score rose from 53.88 preoperatively to 86.24 postoperatively, and mean real IKDC score from 45.15 to 73.92 (P<0.001). Patellar tilt decreased significantly between pre- and postoperative X-ray (P<0.001). DISCUSSION: MPFL gracilis reconstruction provides good clinical results and good radiologic correction of patellar tilt, making it a technique of choice in the treatment of objective patellar instability. LEVEL OF EVIDENCE: Level IV. Retrospective case series study.

[Ab] Abstract:PURPOSE: To evaluate the effectiveness and safety of a fixation technique for comminuted patellar fracture using non-absorbable suture cerclage and nickel-titanium patellar concentrator (Ni-Ti PC). METHODS: Twenty-nine consecutive patients with displaced comminuted patellar fractures accepted internal fixation procedure using Ni-Ti PC augmented with different types of non-absorbable suture cerclage. During follow-up, the clinical grading scales of Böstman, including range of movement, pain, work, atrophy, assistance in walking, effusion, giving way, and stair-climbing, were used to evaluate the clinical results. Complications including implant loosening, fragment displacement, bone nonunion, infection, breakage of the implants, painful hardware, and post-traumatic osteoarthritis were also assessed. RESULTS: Patients were followed up for a mean period of 27 months. The bone union radiographically occurred approximately 2.5 months without implant loosening and fragment displacement. According to Böstman method, satisfactory results were obtained, and the mean score at final follow-up was 28 (range 20­30) points. Twenty-two patients with excellent results had mean score of 29.8 ± 0.5 (range 28­30) and seven patients with good results had mean score of 22.7 ± 3.14 (range 20­27). No postoperative complications, such as infection, dislocation, breakage of the implants, painful hardware, and post-traumatic osteoarthritis, were observed. CONCLUSION: Ni-Ti PC fixation with non-absorbable suture cerclage is a feasible approach for comminuted patellar fractures. Firm fixation with this technique resulted in satisfactory outcomes without obvious complications.

[Ti] Title:TBC1D7 mutations are associated with intellectual disability, macrocrania, patellar dislocation, and celiac disease.

[Ab] Abstract:TBC1D7 forms a complex with TSC1 and TSC2 that inhibits mTORC1 signaling and limits cell growth. Mutations in TBC1D7 were reported in a family with intellectual disability (ID) and macrocrania. Using exome sequencing, we identified two sisters homozygote for the novel c.17_20delAGAG, p.R7TfsX21 TBC1D7 truncating mutation. In addition to the already described macrocephaly and mild ID, they share osteoarticular defects, patella dislocation, behavioral abnormalities, psychosis, learning difficulties, celiac disease, prognathism, myopia, and astigmatism. Consistent with a loss-of-function of TBC1D7, the patient's cell lines show an increase in the phosphorylation of 4EBP1, a direct downstream target of mTORC1 and a delay in the initiation of the autophagy process. This second family allows enlarging the phenotypic spectrum associated with TBC1D7 mutations and defining a TBC1D7 syndrome. Our work reinforces the involvement of TBC1D7 in the regulation of mTORC1 pathways and suggests an altered control of autophagy as possible cause of this disease.

[Ti] Title:Spontaneous bilateral avulsion fracture of the tuberositas tibiae in a New Zealand White rabbit - A counterpart to Osgood-Schlatter disease in humans?

[Ab] Abstract:The first reported case describing a spontaneous bilateral avulsion fracture of the tuberositas tibiae in a New Zealand White rabbit is presented. So far in animals, this condition has been only described in dogs and horses. In humans, this condition is also called Osgood-Schlatter disease (OSD) or syndrome, traction apophysitis of the tibial tubercle (ATT) or patellar tendon enthesopathy of the tibial tuberosity respectively. It is mainly seen in young adolescents coinciding with periods of growth spurts. In humans, its pathogenesis is believed to be caused by repetitive tendon/muscle strain at the insertion of the patellar tendon to the immature tibial tuberosity, which has its own secondary ossification center. Morphologically this case is characterized by bilateral chronic avulsion with incomplete separation of the tuberositas tibae, and proximal dislocation of the patella (patella alta). Despite these marked pathological changes, the animal was clinically without findings. Nevertheless, this case emphasizes the need for thorough clinical and radiological examination of rabbits intended for preclinical research studies prior to study begin, especially in orthopedic research.

[Ab] Abstract:PURPOSE: The present study reports a long-term follow-up of acute primary patellar dislocation in patients with open physes. The purpose of the study was to evaluate knee function and recurrence rates after surgical and nonsurgical treatment of patellar dislocation. METHODS: A total of 51 patients, including 29 girls and 22 boys, who were 9-14 years of age at the time of injury, were retrospectively evaluated. The minimum follow-up time was 5 years. Thigh muscle torque, range of motion, the squat test, the knee injury and osteoarthritis outcome score (KOOS), the Kujala score, and the recurrence rate were registered. Radiological predisposing factors at the time of injury were determined. RESULTS: Quality of life and sports/recreation were the most affected subscales, according to KOOS, and a reduced Kujala score was also observed in all treatment groups. The surgically treated patients had a significantly lower recurrence rate. Those patients also exhibited reduced muscle performance, with a hamstring to quadriceps ratio (H/Q) of 1.03. The recurrence rate was not correlated with knee function. CONCLUSIONS: Patellar dislocation in children influences subjective knee function in the long term. Surgery appears to reduce the recurrence rate, but subjective knee function was not restored.

[Ab] Abstract:Patellar instability is a common problem, and medial patellofemoral ligament (MPFL) injury is inherent with traumatic patellar dislocations. Initial nonoperative management is focused on reconditioning and strengthening the dynamic stabilizers of the patella. For those patients who progress to recurrent instability, further investigation into the predisposing factors is required. MPFL reconstruction is indicated in patients with recurrent instability and insufficient medial restraint due to MPFL injury. A technique of MPFL reconstruction is outlined. This procedure may also be performed in combination with other realignment procedures.

[Ab] Abstract:Patellar instability is a common injury that can result in significant limitations of activity and long-term arthritis. There is a high risk of recurrence in patients and operative management is often indicated. Advances in the understanding of patellofemoral anatomy, such as knowledge about the medial patellofemoral ligament, tibial tubercle-trochlear groove distance, and trochlear dysplasia may allow improved surgical management of patellar instability. However, techniques such as MPFL reconstruction are technically demanding and may result in significant complication. The role of trochleoplasty remains unclear.

[Ti] Title:Surgical versus non-surgical management for primary patellar dislocations: an up-to-date meta-analysis.

[Ab] Abstract:The aim of this up-to-date meta-analysis was to compare the effects of surgical versus non-surgical treatment of patients following primary patellar dislocation and to provide the best evidence currently available. A comprehensive literature search was conducted using multiple databases, including Medline, Embase, and Cochrane Registry of Clinical Trials. All databases were searched from the earliest records to May 2013. Eligible studies were selected, and data were extracted by two independent investigators. The primary outcome variable was the frequency of recurrent patellar dislocation. The other outcomes included knee function scores, patient-rated outcomes, and radiographic examination. If appropriate, meta-analysis of these variables was performed. Nine independent trials were found to match the inclusion criteria. The pooled results demonstrated that the incidence of recurrent patellar dislocation and Hughston visual analog scale was significantly lower in the surgical treatment group than that in the non-surgical treatment group (P < 0.05). There was no statistically significant difference between the two treatment groups in frequency of subsequent surgical interventions, percentage of excellent or good subjective opinion, Kujala score, pain score on visual analog scale, and severity of patellofemoral joint osteoarthrosis (P > 0.05). This up-to-date meta-analysis indicates that surgical treatment was associated with a lower risk of recurrent patellar dislocation, but a lower Hughston VAS than non-surgical treatment for primary patellar dislocation. More large high-quality trials and further studies are needed to overcome the limitations of small sample sizes, and varieties of different surgical procedures or non-surgical management strategies adopted in the included trials.
