There is evidence showing that mesenchymal stromal cells (MSC) may constitute a potential therapeutic strategy to induce bone regeneration. In this work, we investigate the capacity of autologous bone marrow (BM) MSC loaded on collagen microspheres (CM) and included into autologous platelet-rich plasma (PRP) clots (MSC/CM/PRP) to induce bone formation in patients with nonunion lesions. ⋯ Our results support the use of autologous MSC transplanted as MSC/CM/PRP for the treatment of nonunion fractures. Future studies incorporating a larger number of patients may confirm the results obtained in this work.

To determine whether radiographic measurements derived from standard computed tomography (CT) evaluation can be used to predict likelihood of a peri-operative lateral femoral wall fracture in AO/OTA 31-A2 pertrochanteric fractures treated with a dynamic hip screw (DHS). ⋯ AO/OTA 31-A2 pertrochanteric fractures with a lateral wall height of > 1.68 cm and an anterior component of > 2.10 cm in circumference are not likely to sustain a lateral wall fracture when treated with a DHS.

The purpose of this study was to determine the outcomes in patients treated with robotically assisted patello-femoral arthroplasty (PFA). ⋯ The early retrospective data for robotically-assisted PFA show encouraging results. Advantages of this technique include a smaller incision, faster rehabilitation, preservation of bone stock, and implantation without malalignment.

Review Meta Analysis
Adductor canal block provides better performance after total knee arthroplasty compared with femoral nerve block: a systematic review and meta-analysis.
The methods for pain control after total knee arthroplasty (TKA) vary and have been extensively studied in recent years. Femoral nerve block (FNB) is used as the standard method due to its effective pain control following TKA, but it may weaken the quadriceps strength. Adductor canal block (ACB) is a newly developing analgesic protocol with fast functional recovery and good pain control after TKA. A meta-analysis was conducted to try to find out if ACB is better than FNB in pain treatment and joint functional recovery after TKA. ⋯ ACB provide better ambulation ability, faster functional recovery and better pain control at rest after TKA compared to FNB. The use of ACB post TKA is worthy of being recommended to replace FNB as a standard analgesic protocol for pain treatment after TKA.
