RESUMO
BACKGROUND: There are anatomical differences in the femur and acetabulum on the dysplastic hips. Yet, although there are detailed researches on bony structure differences, studies regarding anatomical differences for the vascular structure are insufficient. The study aimed to determine the relationship between the femoral artery and vein with acetabulum in computed tomography evaluation of Crowe type 4 hips and to compare with normal hip femoral vein and artery anatomic position. METHODS: Forty patients with one side hip Crowe type 4 deformity and opposite side normal hip were found suitable for the study. Pelvis CT was previously applied to all patients for the planning of total hip arthroplasty surgery. Normal hip acetabulum and the true acetabulum of the dysplastic hip were marked with the Ranawat's triangle and were then divided into quarters with four axial slices of the acetabulum; as dome, proximal one-fourth, center, and distal three-fourths. The shortest distance from the femoral vessels to the pelvis was measured at these 4 axial slices at the dysplastic side and compared with the healthy side. RESULTS: The distance of the vein to the acetabulum is closer to the dysplastic side. At distal three-fourths of Ranawat's triangle axial images, both femoral artery and femoral vein are closer to acetabulum at the dysplastic side. CONCLUSION: The analysis of preoperative images in cases of Crowe type 4 hip shows that the femoral vessels are closer to the anterior wall of the dysplastic true acetabulum at the level of the center of the hip (vein, mean: 2.7 mm closer) and below the center of the hip (vein, mean: 3 mm; and artery, mean: 3.3 mm closer) when compared with the normal acetabulum. Anatomic relationships knowledge can be used intraoperatively to avoid iatrogenic vascular injury during Crowe type 4 dysplastic hip arthroplasty surgery.

PURPOSE: The purpose of this study was to evaluate the role of surgeons' experience with meniscal repairs and meniscectomy decisions, and to determine the factors affecting the disagreement between meniscal repairs and meniscectomy decisions. METHODS: In total, 223 patients with meniscal tears, 106 meniscal repairs, and 117 meniscectomies were included. Six orthopedic surgeons (3: > 5 years; 3: < 5 years' arthroscopy experience) were blinded, and they independently reviewed all preoperative MR images for over a month. Their reviews were compared with arthroscopic interventions performed by a surgeon with > 10 years' arthroscopy experience. Reparability-associated factors were also evaluated using multivariate logistic regression. RESULTS: The first and second evaluation results did not differ significantly between groups (n.s.). There was good agreement between MRI predictions and arthroscopic interventions for both groups (< 5 years' experience: k = 0.248, agreement 62.3%; > 5 years' experience: k = 0.351, agreement 67.3%). Sex, side, and distance of tear from the meniscocapsular junction were not significantly different between agreements and disagreements. Disagreement regarding meniscectomy was significantly higher than those regarding meniscus repair (p = 0.002). Concomitant anterior cruciate ligament (ACL) injury, osteochondral lesions, and medial meniscal tear increased the likelihood of meniscal repair (p = 0.0063, p = 0.0010, and p = 0.0369, respectively). An increased risk of disagreement between MRI and surgical procedure was found in the presence of bucket-handle, horizontal or complex tear, chronic tear, high sports activity and expectation level. CONCLUSION: Surgeon's experience level may influence the prediction of meniscus reparability. Concomitant ACL injury, osteochondral lesions, and presence of medial meniscal tear increase the likelihood of meniscal repair. Tear type, tear chronicity, patient's activity and expectation level may influence the surgeon's operative decision in addition to MRI. LEVEL OF EVIDENCE: III.

BACKGROUND: Some patients experience a non-traumatic pain in the tibial diaphysis similar to that in the clinical and radiological findings of a tumor, an infection or a stress fracture and cannot be definitively diagnosed even after biopsy. In this study, our aim was to exhibit the challenges in the diagnosis of this patient group and to evaluate this type of patients with a limited population in the literature. METHODS: Eighteen extremities of 16 patients, whose complaints of non-traumatic pain in the tibial diaphysis were evaluated by our tumor council and T2-weighted MR scans of the medullary bone had shown hyperintense signal changes or tumor-like appearances, were evaluated with histological, radiological, and clinical results. RESULTS: Lesions were detected in 18 extremities of the 16 patients (seven males, nine females; mean age 23 [range 7 to 51] years). Four of the lesions were in the right tibial diaphysis, ten were in the left, and two were bilateral. Laboratory findings of the patients were normal. Based on the decision of the tumor council, biopsy was performed on 12 patients. All patients' complaints were gone and MRI findings decreased during the follow-up period. The complaints of the three patients who did not have a biopsy decreased after a mean period of three months. CONCLUSIONS: Medullary stress syndrome has been reported in the literature in various forms and in a limited number of cases, including longitudinal stress fracture and transient medullary edema of the bone. In light of our findings, we deduced that biopsy of the diaphyseal lesions in this patient group is essential and that the complaints of this patient group declined in the earlier term in comparison to the patients who were not performed biopsy.

PURPOSE: Tibia plateau fracture (TPF) treatment aims at achieving a stable, aligned, mobile, painless knee and preventing post-traumatic osteoarthritis. To achieve this goal, surgeons consider criteria such as patients' characteristics, severity, risk of complications, fracture displacement/depression, degree of soft tissue injury. However, body mass index (BMI) is not considered as a risk factor in literature. Our study was conducted to find out any possible correlation between BMI and functional scores or radiological score separately. METHODS: Retrospective analysis of case series between 2011 and 2014 was done on the database of a tertiary hospital in Istanbul. There were 67 TPF patients (54 males, 13 females) in the study. Relationship between BMI and functional knee scores or radiological score was compared statistically. Closed fractures with both high-energy and low-energy injury were included in the study. Patients with open fracture, multi-trauma presence, meniscus and/or ligamentous injury, increased co-morbidity, inadequate records (25 cases in all) were excluded. Surgery type, Schatzker classification, injury side, trauma energy, and gender were considered as possible risk factors. Binary regression analysis was done for possible factors affecting functional knee scores and radiologic score. RESULTS: Model summary calculations were done as Nagelkerke R2 test for Knee Society score, Lysholm knee score, and Ahlback and Rydberg radiologic scores, which were 0.648, 0.831, and 0.327 respectively. Homer-Lemeshow test values were 0.976, 0.998, and 0.362, respectively. There is negative correlation between BMI and both knee function scores. There is no correlation between BMI and radiologic score. CONCLUSION: An increase in BMI has a negative effect on functional knee scores after surgical treatment of TPFs. Therefore, BMI should be considered as a risk factor for surgical treatment of TPFs.

OBJECTIVES: The aim of this study was to evaluate clinical and functional outcomes following the arthroscopic medial meniscal repair. PATIENTS AND METHODS: A total of 50 patients (42 males, 8 females; mean age: 32.9±7.6 years; range, 17 to 48 years) who underwent arthroscopic repair for longitudinal and bucket-handle medial meniscal tears between March 2005 and October 2011 were retrospectively evaluated. The patients were divided into two groups as those having a longitudinal tear (patient group, n=31) and having a bucket-handle tear (control group, n=19). Preoperative and final follow-up functional outcomes were evaluated using the Lysholm Knee Score (LKS), International Knee Documentation Committee (IKDC) score, Tegner Activity Scale (TAS) score, and Knee Injury and Osteoarthritis Outcome Score (KOOS). RESULTS: The mean follow-up was 61.7±22.8 (range, 36 to 110) months. The mean preoperative LKS, IKDC score, TAS, and KOOS scores were significantly improved at the final postoperative follow-up (p<0.05). There was no significant difference in functional outcome scores between longitudinal and bucket-handle repairs (p>0.05), and isolated repairs and concomitant meniscal repair and anterior cruciate ligament reconstruction (p>0.05). CONCLUSION: Arthroscopic meniscal repair provides similar mid-term functional and clinical outcomes for longitudinal and bucket-handle medial meniscal tears. Concomitant meniscal repair does not seem to affect meniscal healing.

OBJECTIVE: The aims of this study were, first, to assess the loss of reduction after fixation of Rockwood type V acromioclavicular joint dislocation (ACJD) with the TightRope device (Arthrex, Naples, FL, USA) and, second, to present the functional and radiological outcomes of this treatment. METHODS: We retrospectively reviewed the medical records of 15 patients (12 males; mean age=39.2 years; age range=23-61) with Rockwood type V ACJD who were treated by the TightRope fixation device. The mean follow-up period was 19.3 (range=12-30) months. Functional status was assessed using the Constant-Murley score (CMS) at the final follow-up examination. To determine the reduction loss of ACJ, we measured and compared the coracoclavicular (CC) distance using radiographs with Zanca view in the early postoperative period and at the final follow-up examination. The fixation procedures were performed with an open technique using the TightRope fixation device. RESULTS: The mean CMS at the final follow-up was 93.2 (range=82-100) points. All the patients experienced full recovery of the shoulder's range of motion, were able to return to the activities of daily living, and were satisfied with the treatment. ACJ reduction was successfully achieved in all the patients using the TightRope technique. Postoperative radiographs revealed no reduction loss in the ACJ, and the CC distance was well maintained. The mean CC distance was 19.95 (range=13.1-28.3) mm before surgery. The mean CC distance was 7.47 (range=4.2-11.5) mm in the early postoperative radiographic measurements. This difference was statistically significant (p=0.001). The mean CC distance at the final follow-up examination was 7.70 (range=4.5-11.7) mm. At the final follow-up visit, the shoulders of all the patients were still completely reduced, with a mean difference in the CC of 0.23 (range=0-1.3) mm compared with that in the early postoperative period. The difference in the CC between the early postoperative and final follow-up intervals was not statistically significant (p=0.055). No patient experienced recurrence or required an operation for hardware removal. CONCLUSION: It seems that the TightRope device can provide anatomical restoration in patients with acute type V ACJD without subluxation at the final follow-up examination. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

BACKGROUND: In clinical practice, soft tissue interposition may occur during femoral graft fixation. Soft tissue interposition between the lateral femoral cortex and the cortical button may affect graft tension and related longitudinal graft motion in the tunnel. We aimed to investigate the effect of soft tissue interposition on button migration and clinical outcomes in anatomical single-bundle anterior cruciate ligament reconstruction. METHODS: Eighty-four patients aged 18-40 years, who underwent anatomical single-bundle anterior cruciate ligament reconstruction with quadruple hamstring autograft were included. Patients were divided into two groups as Group 1 (n = 32) with soft tissue interposition between the cortical button and cortex, and Group 2 (n = 52) without soft tissue interposition. At the one-year follow-up visit, the anteroposterior knee stability of the patients was evaluated using the Lachman test and KT-2000 arthrometer, and rotational stability was assessed with the pivot shift test. The Lysholm knee score was used to evaluate the functional outcome of the patients. Relationship between tissue interposition and clinical outcome, and button migration was examined. RESULTS: Button migration was observed in 12 patients in Group 1 (37.5%) and two patients (3.84%) in Group 2 (p < 0.001). However, no significant difference was observed between patients with and without tissue interposition or those with and without button migration regarding knee stability parameters and clinical outcome (p < 0.05). CONCLUSIONS: Postoperative tissue interposition is found to be associated with cortical button migration during the follow-up. However, it does not affect the clinical outcome.

PURPOSE: To evaluate the short-term clinical and radiological outcomes with degenerative changes in patients over 40 years old following isolated vertical medial meniscal tear repair. METHODS: Between 2007 and 2015, 438 patients underwent arthroscopic meniscal repair. Thirty-three patients aged over 40 years with isolated vertical medial meniscal repair (23 males and 10 females, mean age 46.1 ± 7.0; range 40-67) were included in the study. Preoperative and postoperative physical examination findings, Lysholm knee score, the International Knee Documentation Committee score, magnetic resonance imaging findings, and Kellgren-Lawrence osteoarthritis stage were evaluated. RESULTS: The mean follow-up period was 31.1 months ± 20.1 (range 12-100 months). There was statistically significant improvement in functional scores ( p < 0.05) and physical examination findings. In 22 patients (66.7%), improvement in the clinical and radiological results was detected ( p < 0.05). However, no correlation was found between clinical and radiological outcomes. There was also no significant change in osteoarthritis stages at the last follow-up visit. No significant difference was found between smokers and nonsmokers regarding clinical outcomes. CONCLUSION: Successful clinical and radiological outcomes can be obtained following isolated vertical medial meniscal tear repair in patients older than 40 years. Age is not the sole criterion for the success of meniscal repair; rather, the functional capacity of the patient, the location of the tear, the grade of knee joint arthritis, and the quality of the meniscal tissue should be taken into consideration.

The literature contains very limited articles wherein the treatment results of bucket-handle meniscal tears according to various types are evaluated and wherein results for repair of chronic tears are discussed. The objective of this study is a clinical and radiologic evaluation of arthroscopic repair for patients suffering flipped, neglected chronic bucket-handle meniscal tear in the intercondylar notch. A total of 26 patients were evaluated retrospectively. The mean age at the time of surgery was 27 years (range, 16-44). Mean period from meniscal injury to surgery was 28 months (range, 4-96). The mean follow-up period was 31 months (range, 11-67). During the follow-up, the patients were evaluated clinically, functional scores from the International Knee Documentation Committee (IKDC), Lysholm, and Tegner as well as magnetic resonance imaging (MRI). The mean preoperative Lysholm score of 24 increased to 85 postoperatively. Mean IKDC score was 56.3 preoperatively and 84.5 postoperatively. The mean Tegner score of 3.4 increased to 5.6 postoperatively. Mean Lysholm, IKDC, and Tegner scores in the first group were 84, 74, and 5.1, respectively, and in the anterior cruciate ligament (ACL) reconstruction group; 86, 85.9, and 5.8. While 20 (77%) out of 26 patients had none of the clinical findings, 6 patients (23%) presented with these findings. Postoperative MRI assessment revealed meniscal healing in 21 patients (27% complete, 54% partial healing) and no healing in 5 patients (19%). A clinical healing rate of 77% and a radiological healing rate of 81% along with statistically significant increases in Lysholm, IKDC, and Tegner scores prove that the repair option is effective for neglected, chronic bucket-handle meniscal tears flipping to the intercondylar notch. This study showed that good results could be achieved with the repair of neglected, chronic period bucket-handle meniscal tears flipping to the intercondylar notch, whether with an accompanying ACL tear or not.

INTRODUCTION: Piriformis syndrome involves the irritation of the piriformis muscle due to various reasons that are primarily related to anatomical variation or sciatic nerve compression due to contraction caused by overuse. In this study, we aimed to define an injection method that is easy to apply, safe, simple and repeatable. MATERIALS AND METHODS: We administered percutaneous lidocaine and depomedrol injections into the hips of 28 patients (14 men and 14 women) under fluoroscopic control. Bipolar injections of the piriformis muscle were performed at the medial pole, the intersection of the sciatic notch and the sacroiliac joint, and at the lateral pole of the femoral insertion region. Each injection was 5 cc, and the contrast agent was observed after the dyeing process. RESULTS: Clinical examinations were performed before and 6 weeks after the injections. The average of Harris Hip Score increased from a pre-injection score of 44.5 to a post-injection score of 68.5, and the Visual Analog Scale scores decreased from 8.3 to 4.2 (p<0.05). COMMENTS: Our findings lead to the conclusion that fluoroscopy-guided percutaneous local anaesthetic and corticosteroid injection is a simple and effective piriformis syndrome treatment that can feasibly be effectively performed by orthopaedic surgeons.
