Background: This retrospective study aimed to compare the clinical and radiological results of clavicular hook plate fixation versus suture-button fixation of acromioclavicular joint (ACJ) dislocations.Methods: 21 patients are retrospectively evaluated in the present study whom diagnosed as type III-V ACJ dislocations and treated by two different surgical methods. The hook plate group comprised 9 patients to whom acromioclavicular fixation. The suture-button group comprised 12 patients to whom coracoclavicular fixation. All patients were evaluated by Constant Murley Score (CMS) and visual analogue score (VAS). Loss of reduction and radiological results were evaluated with the coracoclavicular distance (CCD). Results:The average follow-up was 31 months (range, 15-56 months). There was no significant difference between hook-plate and suture-button groups in terms of CMS. However, VAS in hook plate group better than suture-button group (p = 0.038). Suturebutton fixation adjusted the CCD more than hook plate fixation compared to the opposite shoulder (p = 0.482). Conclusions:There was no statistically significant difference between the hook plate and suture-button group in terms of the clinical outcomes. However, CCD in the suture-button group was better adjusted to the hook plate group. Suture-button fixation is a good option for the treatment of ACJ dislocations, as implant removal may be required in most cases in which the hook plate is applied.

The aim of this study was to investigate the corrective effect of Oxford phase 3 medial unicompartmental knee arthroplasty (UKA) on the lower extremity axis, tibiofemoral subluxation and lateral joint distance. Materials and Methods:The study included 105 knees that had undergone UKA. The Oxford Knee Score, EQ-5D-3LD and visual analog scale, and The Knee injury and Osteoarthritis Outcome Score were evaluated. Radiological evaluation was made of the lower extremity axis, tibiofemoral subluxation, and lateral knee joint distance. Results: The postoperative mean improvement in the mechanical axis was 1.4° and in the tibiofemoral subluxation distance, 1.59 mm compared to preoperative values. The difference between the preoperative and postoperative lateral joint distance values was on average 0.25 mm lateral inner joint distance, 0.08 mm in the lateral middle joint distance and 0.34 mm in the outer joint distance. There was no significant difference in clinical results between the groups. Conclusion: There were significant improvements in the postoperative period after cemented, cementless, and hybrid medial UKA in the measurements of lower extremity mechanical axis, tibiofemoral subluxation distance and lateral joint distances compared to the preoperative period. Amaç: Bu çalışmanın amacı, Oxford faz 3 medial unikompartmantal diz artroplastisinin (UDA) alt ekstremite ekseni, tibiofemoral subluksasyon ve lateral eklem mesafesi üzerindeki düzeltici etkisini araştırmaktı. Gereç ve Yöntem: Çalışmaya UDA yapılan 105 diz dahil edildi. Oxford Diz Skoru, EQ-5D-3LD, vizüel analog skalası ve diz yaralanması ve osteoartrit sonuç skorları değerlendirildi. Alt ekstremite aksı, tibiofemoral subluksasyon ve lateral diz eklem mesafesinin radyolojik değerlendirmesi yapıldı. Bulgular: Preoperatif değerlere göre mekanik eksende postoperatif ortalama düzelme 1.4 ° ve tibiofemoral subluksasyon mesafesinde 1.59 mm idi. Preoperatif ve postoperatif lateral eklem mesafesi değerleri arasındaki fark ortalama 0,25 mm lateral iç eklem mesafesi, lateral orta eklem mesafesinde 0,08 mm ve dış eklem mesafesinde 0,34 mm. Gruplar arasında klinik sonuçlarda anlamlı bir fark yoktu. Sonuç: Alt ekstremite mekanik aks, tibiofemoral subluksasyon mesafesi ve lateral eklem mesafelerinin ölçümlerinde çimentolu, çimentosuz ve hibrid medial UDA sonrası postoperatif dönemde preoperatif döneme göre anlamlı iyileşmeler vardı.
