Observational StudyPreoperative soft tissue laxity around knee was associated with less accurate alignment correction after hybrid closed-wedge high tibial osteotomy.
This study aimed to assess the effect of soft tissue correction due to knee joint laxity, which induces alignment error after hybrid closed-wedge high tibial osteotomy (CWHTO). In addition, to verify whether postoperative soft tissue correction can be predicted from preoperative radiographic parameters. ⋯ Preoperative values for JLCA and JLCA under valgus stress are associated with soft tissue correction. Surgeons should, therefore, consider these measurements to achieve postoperative limb alignment.

To understand the feasibility, clinical effect, and complications related to biological reconstruction techniques for long limb malignant bone tumors after excision. This retrospective study included eighty patients with malignant bone tumors treated at our hospital between January 2007 and January 2019. After tumor resection, 52 cases of intercalary and 28 cases of osteoarticular bone grafts were used. ⋯ Postoperative complications included delayed bone union in 15 patients, fractures in 25 cases, nonunion in 22 cases, bone resorption in 14 cases, and postoperative infection in 4 cases. Twenty-eight cases of bone grafting required revision surgery, including replacement of internal fixation, autologous bone graft, debridement, removal of internal fixation, and replacement with prosthetic replacement. Biological reconstructions with massive bone grafts are useful in the reconstruction of certain malignant extremity bone tumors after wide excision.

Management Of Segmental Fracture Of Tibia Treated By Ilizarov External Fixation.
Tibial shaft segmental fractures are mostly occurring due to a high-energy trauma that produces a severe soft-tissue injury and resulting an excessive frequency of open and closed segmental fractures, and needs effective stable management. The objective of the study was to evaluate the functional outcome and union time in segmental tibial fracture treated with Ilizarov method. ⋯ Ilizarov is an effective method for the stabilization of segmental tibial fractures because the method allows close reduction without extensive soft tissue damage and is efficient for the stabilization of short distal segmental fractures of the tibia.

Accuracy of tibial positioning in the frontal plane: a prospective study comparing conventional and innovative techniques in total knee arthroplasty.
Coronal alignment of the tibial component determines functional outcome and survival in total knee arthroplasty (TKA). Innovative techniques for tibial instrumentation have been developed to improve accuracy and reduce the rate of outliers. ⋯ The navigation and intramedullary instrumentation provided the precise positioning of the tibial component. Outliers were most common within the PSI and extramedullary technique. Optimal alignment is dependent on the technique of tibial instrumentation and tibial component positioning determines the accuracy in TKA since mTFA correlated with MPTA pre- and postoperatively.

Three-point Method to Guide the Tibial Resection and Component Placing in Total Knee Arthroplasty.
To introduce a three-point method combining the midpoint of the posterior cruciate ligament (PCL), the midsulcus of the tibial spines, and the midpoint of the anterior cruciate ligament (ACL) to determine appropriate tibial resection and component placing during TKA and to compare this method with Insall's 1/3 method. ⋯ The line connecting the midpoint of the PCL, the midsulcus of the tibial spines, and the midpoint of the ACL could be used as the reference for the tibial resection and component placing. This method appears to be more accurate than Insall's 1/3 method. The results of this study provide a candidate method for component orientation with little error.
