Background:It is a randomized study to compare cement penetration on x-rays after total knee arthroplasty (TKA) among 3 different ways to use tourniquets; application during the surgery, application only with implantation prosthesis and with no tourniquet use.Methods:A total 69 knees of 59 patients were included in the study in a quasirandom manner. Each patient had physical exams and standard radiographic evaluations at 6 weeks after the TKA procedure. Outcome evaluations included visual analog scale (VAS) scores, Knee Society Scores (KSS), blood transfusion, and drainage status after surgery for all groups. For radiographic review, the tibial plateau was divided into zones in the anterior–posterior and lateral views, according to the Knee Society Scoring System.Results:The average age of the patients who were eligible for the study was 65.05 (range 46–81) years. All 59 patients included in the study were female patients. Group 1 consisted of 24 patients who had TKA with use of a tourniquet during the entire operation. Group 2 consisted of 20 patients who had TKA with use of tourniquet only at the time of cementing and group 3 consisted of 25 patients with no use tourniquet. There is no significant difference in early cement penetration among the groups (group 1 2.50 mm, group 2 2.28 mm, group 3 2.27 mm; group 1 vs 2 P = .083, group 1 vs 3 P = .091, group 2 vs 3 P = .073). There is no significant difference for postoperative drainage among the 3 groups (group 1 245 mL, group 2 258.76 mL, group 3 175.88 mL; group 1 vs 2 P = .081, group 1 vs 3 P = .072, group 2 vs 3 P = .054). There was no need to transfuse more than 1 unit in any patient. The VAS score was significantly higher (group 1 3.58, group 2 1.55, group 3 1.52; group 1 vs 2 P = .022, group 1 vs 3 P = .018, group 2 vs 3 P = .062) and KSS was significantly lower in the tourniquet group (group 1 63, group 2 79, group 3 82; group 1 vs 2 P = .017, group 1 vs 3 P = .02, group 2 vs 3 P = .082).Conclusion:We do not suggest long-duration tourniquet use, which can lead higher pain scores and reduce functional recovery after total knee arthroplasty.

HighlightsSkeletal deformity surgery is a difficult procedure which requires meticulous planning.Good results demand precise application of the surgical plan during the surgery.3D software helps to make precise surgical plans and design case specific surgical tools.3D printing of case specific tools renders surgery easy and precise.

Subacromial impingement is one of the most common causes of painful shoulder in the middle aged and elderly population. Since Neer's first description of the process, many investigators have researched this condition in an effort to gain a better understanding of the disease etiology. The aim of this study was to investigate the relationship between the radiological subacromial distance measurements and the subacromial impingement syndrome in a series of patients from our institution. For this purpose, 44 patients scheduled for a unilateral shoulder arthroscopy were investigated prospectively. The acromio-glenoid angle, supraspinatus-glenoid angle (from coronal MR images) and acromial index (from true anterior-posterior shoulder X-ray images) were measured as the implications of the subacromial distance, and the degree of subacromial impingement was graded according to intraoperative findings. Statistical data analysis revealed no significant correlations between the radiological measurements and the severity of subacromial impingement (p > 0.05). On the other hand, there was a significant correlation (p = 0.0049) between the patient age and subacromial impingement. These results suggest that the radiological subacromial distance measurements do not have enough clinical significance as predictive markers in the subacromial impingement syndrome.

ObjectiveThe aim of this study was to compare the functional and radiological outcomes of vertebroplasty and kyphoplasty in patients with osteoporotic vertebra fractures.MethodsThe files of the patients who underwent vertebroplasty or kyphoplasty for osteoporotic vertebrae fractures were retrieved from the archives. Forty-three patients with complete follow-up data were included in the study group. The patients were evaluated for radiological outcomes in terms of local kyphosis angle, wedging index, compression ratio, visual analog pain scale (VAS) and Oswestry Disability Index (ODI).ResultsIn the study group, kyphoplasty was performed on 24 vertebrae of 22 patients (17 females, 5 males; mean age: 73 years) whereas vertebroplasty was applied on 24 vertebrae of 21 (16 females, 5 males; mean age: 74.7 years) patients. The mean follow-up time was 26 months. When the VAS and ODI values of the groups were analyzed, both groups showed statistically significant progress after the operation. Radiological data showed that the kyphoplasty group showed statistically significant improvement in the sagittal index values whereas the vertebroplasty group did not. The overall complication ratio was 4%.ConclusionBoth vertebroplasty and kyphoplasty are effective treatment methods for functional recovery and pain relief in osteoporotic fractures of the vertebra. Although radiological outcomes of the kyphoplasty seem to be better, this does not have any clinical relevance. We suggest vertebroplasty over kyphoplasty since it is an easier method to manage.Level of evidenceLevel III, Therapeutic study.
