High-Yield Summary Extensor mechanism rupture after total knee arthroplasty (TKA) is a rare but devastating complication that compromises knee extension and function, requiring prompt diagnosis and tailored management. Disruption can involve the quadriceps tendon, patella, or patellar tendon; location and chronicity dictate treatment strategy. Early diagnosis with clinical exam and imaging (radiographs, ultrasound, MRI) is […]
High-Yield Summary The Vancouver Classification stratifies periprosthetic hip fractures by fracture location, implant stability, and bone stock quality, directly guiding management strategy. Type A fractures involve the trochanteric region; Type B fractures occur around or just distal to the stem and are subdivided by implant stability and bone stock; Type C fractures are well distal […]
High-Yield Summary Gap balancing prioritizes soft tissue tension and ligamentous equilibrium to guide femoral component positioning, optimizing flexion and extension gaps for balanced knee kinematics. Measured resection relies on bony landmarks to determine femoral component rotation and bone cuts, assuming soft tissue balance will follow. Both techniques aim to restore mechanical alignment and joint stability […]
High-Yield Summary The mangled patella in revision total knee arthroplasty (TKA) presents a complex challenge requiring restoration of extensor mechanism integrity and stable patellofemoral articulation. Key determinants of management include residual bone stock, soft tissue viability, extensor mechanism competence, and infection status. Classification systems focusing on patellar bone loss and extensor mechanism disruption guide surgical […]
High-Yield Summary ALTR primarily occurs in metal-on-metal and modular total hip arthroplasty components, driven by metal debris-induced immune responses causing soft tissue necrosis and osteolysis. Diagnosis hinges on clinical suspicion, serum metal ion levels, advanced imaging (MARS-MRI), and synovial fluid analysis to differentiate ALTR from infection and mechanical failure. Management requires stratification by symptom severity, […]
High-Yield Summary The Paprosky Classification stratifies acetabular bone loss based on radiographic landmarks and bone stock quality, guiding revision total hip arthroplasty (THA) reconstruction strategies. Type I and II defects have intact columns and generally allow for hemispherical cup fixation; Type III defects involve column deficiency requiring complex reconstruction. Accurate preoperative assessment with AP pelvis […]
High-Yield Summary Periprosthetic femoral fractures (PFF) after total hip arthroplasty (THA) require classification-based management; the Vancouver system remains the gold standard guiding treatment. Stability of the femoral implant and fracture location dictate operative versus non-operative strategies. Type B1 fractures (stable implant) favor open reduction and internal fixation (ORIF), while B2 and B3 (loose implants) require […]
Managing a Patient with Aseptic Loosening of a Joint Implant: A High-Yield Review for Orthopaedic Trainees High-Yield Executive Summary Aseptic loosening is the leading cause of late failure in joint arthroplasty, driven by periprosthetic osteolysis and mechanical instability without infection. Diagnosis hinges on clinical symptoms (pain, instability), radiographic evidence (radiolucent lines, component migration), and exclusion […]
Management of Patients With a History of Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE) Requiring Joint Arthroplasty High-Yield Executive Summary Preoperative risk stratification for thromboembolism is critical; history of DVT/PE significantly elevates perioperative VTE risk in joint arthroplasty. Multimodal thromboprophylaxis combining mechanical and pharmacologic strategies tailored to individual risk profiles optimizes outcomes. Anticoagulation management […]
Assessing Patient Satisfaction After Joint Arthroplasty: A High-Yield Review for Orthopaedic Trainees High-Yield Executive Summary Patient satisfaction after joint arthroplasty is a multidimensional outcome influenced by pain relief, functional improvement, and patient expectations. Preoperative counseling and expectation management are critical determinants of postoperative satisfaction. Standardized, validated tools (e.g., WOMAC, Oxford Hip/Knee Scores, PROMIS) provide objective […]
