Article Abstract
Background: Shaping the trapezium and metacarpal base during first carpometacarpal (CMC) Ensemble arthroplasty traditionally relies on manual rasping. This is time-consuming and poses the risk of iatrogenic nerve injury due to repeated rasping near the dorsal and volar branches of the dorsal radial sensory nerve. This case report presents a novel modification to the surgical technique by integrating a mini power saw to streamline joint space preparation.
Case Presentation: A 56-year-old Caucasian female patient presented with advanced first carpometacarpal osteoarthritis and chronic pain. She underwent multiple rounds of corticosteroid injections into the first carpometacarpal joint that provided only short-term relief. She expressed her desire for long-term relief and underwent Ensemble arthroplasty at the first carpometacarpal with this modification to the technique. Intraoperative fluoroscopy confirmed optimal implant positioning. The patient began occupational therapy 2 weeks post-surgery, attending sessions two to three times per week.
Conclusion: This innovative approach reduced operative time by 20 minutes compared to traditional rasping, with postoperative outcomes comparable to those of the standard technique. This report highlights a potential advancement in surgical efficiency and safety.

The use of cementless total knee arthroplasty (TKA) has significantly increased over the past decade. However, there is no objective criteria or consensus on parameters for patient selection for cementless TKA. The purpose of this study was to develop a machine learning model based on patient and radiographic parameters that could identify patients indicated for cementless TKA.

Background: Proximal tibiofibular joint instability (PTJI) is a rare condition, particularly in total knee arthroplasty (TKA) revision, with only one prior case reported. This case highlights the importance of considering PTJI in patients with chronic lateral knee pain and instability following TKA and demonstrates a novel stabilization approach for managing this challenging condition.
Case Description: A 73-year-old female with a history of multiple knee surgeries presented to our clinic due to increasing lateral knee pain radiating along the syndesmosis, aggravated by activities like squatting.

Background: Accurate and timely differential diagnosis of hip prosthesis failures remains a major clinical challenge. Radiographic examination remains the most cost-effective and common first-line imaging modality for hip prostheses, and integrating deep learning has the potential to improve its diagnostic accuracy and efficiency.
Methods: A deep learning-based clinical classification system (Hip-Net) was developed to classify multiple causes of total hip arthroplasty failure, including periprosthetic joint infection (PJI), aseptic loosening, dislocation, periprosthetic fracture, and polyethylene wear.

Machine learning (ML), a subset of artificial intelligence (AI), utilizes advanced algorithms to learn patterns from data, enabling accurate predictions and decision-making without explicit programming. In orthopedic surgery, ML is transforming clinical practice, particularly in shoulder arthroplasty and rotator cuff tears (RCTs) management. This review explores the fundamental paradigms of ML, including supervised, unsupervised, and reinforcement learning, alongside key algorithms such as XGBoost, neural networks, and generative adversarial networks.
