BackgroundThis study aimed to consider the use of a meniscal repair in patients in order to close the horizontal cleavage extending up to the avascular zone. The hypothesis was to examine the clinical and arthroscopic outcomes following meniscal repair of degenerative horizontal cleavage tears with new-generation all-inside suture materials using the overlock method.MethodsWe retrospectively reviewed a consecutive series of 55 patients which had a horizontal pattern, and finally, 27 patients with a horizontal tear only which required no additional intra-articular surgical intervention were included in the study. Arthroscopic meniscal repair was performed using the overlock method. Functional outcomes were evaluated using Lysholm knee scoring scale, Cincinnati scores, subjective International Knee Documentation Committee (IKDC) criteria and Tegner activity scale. Assessment of meniscal healing was evaluated clinically by the presence of meniscal signs. The preoperative and postoperative MRIs were examined.ResultsThe mean follow-up period was 29 months (range, 24–38). The mean Lysholm score improved significantly from 59.5 ± 12.4 points preoperatively to 90.0 ± 4.7 points postoperatively (P < 0.0001). The Cincinnati score increased from 14.8 ± 5.3 to 26.9 ± 1.6 (P < 0.0001). The Tegner activity score increased from 3.7 ± 1.4 to 6.4 ± 1.6 (P < 0.0001). The mean IKDC subjective score also improved significantly from 48.5 ± 9.8 preoperatively to 90.4 ± 5.0 postoperatively (P < 0.0001).ConclusionMeniscal repair of degenerative horizontal tears using the overlock method resulted in improved Lysholm and IKDC subjective scores. With careful selection of the patients and the horizontal meniscus tears, the success of the meniscus repairs increases. Repair can be recommended for all horizontal meniscus tears which can be repaired arthroscopically.

BackgroundWhether or not there is a relationship between the newly-discovered irisin hormone and bone healing is not yet known. The aim of this study was to investigate what effect irisin hormone has on the bone healing process.Material/MethodsThe study included 21 adult patients with a diagnosed fracture of the lower extremity (femur or tibia). Informed consent was obtained from all the patients. A total of four venous blood samples were taken from the patients: before fracture stabilization, then postoperatively on days 1, 10, and 60. In patients with femoral neck fracture who had hip prosthesis applied, bone tissue samples were taken from the removed femur head and irisin was determined immunohistochemically in muscle biopsies taken from the same patients.ResultsIn analysis, it was revealed that the mean value of irisin 60 days after operation is significantly higher than the values of irisin before operation, 1 day after operation, and 15 day after operation (p<0.001, p<0.001, p<0.001, respectively). Intense staining was observed in compact bone tissue, muscle tissue, and in hypertrophic vascular endothelium within the Havers canal.ConclusionsThe level of irisin hormone increased in the bone union process and affects fracture healing due to irisin receptors in human bone tissue.

ObjectivesPlatelet volume has been defined to be a marker that shows thrombocyte activation and function and it is measured as mean platelet volume (MPV). MPV shows the mean volume of circulating thrombocytes and it is one of the routine parameters in complete blood count. Increased thrombocyte volume is associated with thrombocyte activation.Patients and methodsThis study included 76 patients who were operated on due to fractures of long tubular bones. Patients who had union without any additional interventions were defined as group I, and patients who needed additional interventions due to nonunion or inadequate union were defined as group II. The control group included healthy volunteers who did not have a fracture. Hematologic test values of the patients that were obtained at admission to emergency ward were recorded.ResultsThe groups were not statistically different in terms of age, sex, and the affected extremity. There were significant differences between group I and group II in terms of mean erythrocyte sedimentation rate, C-reactive protein, and MPV values (P<0.001), but there were no significant differences between group I and the control group. There was also no statistically significant difference among groups in terms of hematologic and biochemical variables.ConclusionIn our study, fractures in patients who had lower MPV values than controls during the inflammation process healed without any problem, but fractures in patients with high MPV values more frequently needed additional surgical interventions.

IntroductionFemur neck fracture comprises a significant part of intracapsular femur fracture in the intracapsular area of proximal femur and it is mostly seen in elder people. However, these kinds of fractures may be seen in young adults. The present study aims to search factors that affect femoral neck fractures in young adults after surgery carried out by internal determination method.MethodsFiles of patients who were applied internal determination through closed reduction and cannulated screw because of intracapsular femur neck fractures between 2010 and 2015 were analyzed retrospectively. Fractures were evaluated by means of Garden classification, which is based on radiological appearance. The cases were examined in terms of timing of surgery in two groups. Cases operated in the first 24 hours after trauma consisted of group 1 and after 24 hours group 2. Radiological staging in femoral head avascular necrosis was evaluated by Ficat-Arlet classification system whereas acetabular fractures and hip functionality was evaluated by Letournel and Judet system, which is based on direct graph of fracture line.ResultsMean age at the time of surgery for 31 cases included in the study was 40.04 ± 9.63 year. The average duration from injury to surgery was 6.6 (1-20) days. Thirty nine percent of fractures was nondisplaced whereas 61% was displaced. The average follow-up period was 4.9 ± 1.35 years. The rate of nonunion was found 16% and femoral head avascular necrosis 6.4%. According to Judet System, 67.7% of cases showed excellent/good and 32.3% moderate/bad functional results. Six cases had a secondary surgery. Cases who had displaced fractures statistically showed worse functional results and underwent more secondary surgery than patients with nondisplaced fractures (P>0.05). As a result of logistic regression analysis, presence of displacement was a factor negatively affecting the judet score but did not affect the rate of complication. There were no significant differences between the two groups according to the surgical timing in terms of functional outcomes and complications.ConclusionBecause of surgical treatment of femoral neck fractures in the first 24 hours does not affect functional outcomes and complication rate, surgery is recommended in optimal conditions. In the case of displacement, care must be taken in terms of poor functional results.

IntroductionThe aim of the study is retrospectively investigated durations for returning to work following anatomic ACL reconstruction by hamstring autograft in miners and the reasons in patients who were delayed to return to work.MethodsMiners with symptomatic anterior cruciate ligament rupture underwent arthroscopic reconstruction. Patients were evaluated in terms of range of motion (ROM) values; Lysholm, Cincinati and Tegner activity scales; laxity testing and complications. By modifying the method used by Fitzgerald et al. we decided for the criteria returning to work.ResultsThirty three patients were evaluated with mean followup of 22.7 ± 8.3 months (range 13-46 months). Mean age at the surgery was 27.8 (18-38) years. Lysholm, Cincinati and Tegner activity scales were signifi cantly higher from preoperative scores (Lysholm scores: preoperative: 60.7 ± 12.5, postoperative: 90.3 ± 4.8 (P < 0.001); Tegner activity scores: Preoperative 3.5 ± 1.4, postoperative: 6.2 ± 1.5 (P < 0.001); Cincinati scores: Preoperative: 14.8 ± 5.3, postoperative: 26.9 ± 1.6 (P < 0.001). The average time for returning to work was determined as 15,3 ± 4 weeks. There was no significant difference for knee scores and time for returning to work between patients with meniscal injuries and don't have meniscus lesions.ConclusionThe reasons for delays in returning to work was work accident. Hematoma or effusion and pain inside the knee were the most significant reason which affected returning to work.

BackgroundMeniscocapsular separation (MCS) is a lesion of the area which is attached from the peripheral section of the meniscus to the capsule and is seen less often than other meniscus injuries. The aim of this study was to investigate which of the different side applications of all-inside MCS repair of the meniscus was better in respect of clinical and functional results.MethodsIn this retrospective study, 53 patients with MCS pattern in their knee joints were treated with arthroscopic meniscus repair made with the all-inside method. The patients were separated into three groups according to the surface from which the fixation was applied: group 1, from the femoral joint surface of the meniscus (n = 17), group 2, from the tibial joint surface of the meniscus (n = 21) and group 3, from the femoral and tibial joint surfaces of the meniscus (n = 15). The participants were assessed using the subjective International Knee Documentation Committee Scoring (IKDC), Lysholm Knee Scale, Tegner Activity Level Scale, Barrett criteria and Kellgren–Lawrence classification after a 45 ± 12.1 months (range, 24–70 months) follow-up.ResultsPostoperatively, all the groups exhibited significantly increased subjective IKDC score, Lysholm score and Tegner activity score compared with their preoperative results (p < 0.001). At 6 months postoperatively, a statistically significant difference was determined between the groups in respect of the subjective IKDC score, Tegner activity score and Lysholm score with group 2 showing better results than the other groups (p < 0.001). At the final follow-up examination, no statistically significant difference was determined between the groups in respect of the subjective IKDC score, Tegner activity score or Lysholm score. A statistically significantly lower level of pulling and stress sensation was determined in group 2 (p < 0.001).ConclusionsMCS repair made with the all-inside method is successful clinically and functionally and in respect of MRI findings. In addition, it was seen that the fixation method applied from the tibial surface of the meniscus does not disturb the anatomic position of the meniscus in MCS repair. The tibial joint surface is the most appropriate area for suturation in all-inside repair of MCS.Level of evidenceLevel IV.
