Both NF and HACS with CBMA techniques are beneficial in treatment of osteochondral lesions of the talus. Better clinical and radiological results, in addition to higher cartilage quality, could be obtained with HACS with CBMA technique compared to NF.

This study demonstrated that overhang in the posterolateral region is surprisingly high and negatively affects the clinical results following TKA, thereby presenting a danger to the success of TKA. The risk of posterolateral oversizing can increase with placement of the tibial component in external rotation.

Unsuccessful outcomes after repair of massive rotator cuff ruptures accompanied by muscle atrophy and fatty degeneration are frequently associated with inadequate management and secondary tears. We report the functional differences after rotator cuff rupture repair with a biodegradable spacer application. In these patients, rotator cuff rupture repair should provide coverage of the humeral head. Subsequently, acromioplasty should be performed to allow adequate space for the subacromial spacer. Thereafter measurement of the intra-articular space required for application of the biodegradable spacer is performed. Using this method can decrease the rate of tears by providing a safe subacromial space in cases of massive rotator cuff rupture.

Objective. Tranexamic acid (TXA) is increasingly used in orthopedic surgery to reduce blood loss; however, there are concerns about the risk of venous thromboembolic (VTE) complications. The aim of this study was to evaluate TXA safety in patients undergoing lower limb orthopedic surgical procedures. Design. A meta-analysis was performed on the PubMed, Web of Science, and Cochrane Library databases in January 2020 using the following string (Tranexamic acid) AND ((knee) OR (hip) OR (ankle) OR (lower limb)) to identify RCTs about TXA use in patients undergoing every kind of lower limb surgical orthopedic procedures, with IV, IA, or oral administration, and compared with a control arm to quantify the VTE complication rates. Results. A total of 140 articles documenting 9,067 patients receiving TXA were identified. Specifically, 82 studies focused on TKA, 41 on THA, and 17 on other surgeries, including anterior cruciate ligament reconstruction, intertrochanteric fractures, and meniscectomies. The intravenous TXA administration protocol was studied in 111 articles, the intra-articular in 45, and the oral one in 7 articles. No differences in terms of thromboembolic complications were detected between the TXA and control groups neither in the overall population (2.4% and 2.8%, respectively) nor in any subgroup based on the surgical procedure and TXA administration route. Conclusions. There is an increasing interest in TXA use, which has been recently broadened from the most common joint replacement procedures to the other types of surgeries. Overall, TXA did not increase the risk of VTE complications, regardless of the administration route, thus supporting the safety of using TXA for lower limb orthopedic surgical procedures.
