Title: MSC Week 3 – Knee Practice Exam (60+ Questions) | TKA, Anatomy, Imaging, Implants | 2025/2026

This document contains 60+ detailed multiple-choice questions with correct answers from Week 3 of an MSC (Medical Surgical Clinical) module, focusing on the knee joint. Designed for the 2025/2026 academic year, this practice exam is a valuable resource for students in Orthopedic Surgery, Physical Therapy, Radiology, Medical Technology, and Biomedical Engineering programs. Topics covered include: Knee anatomy: bones, compartments, axes (anatomical, mechanical, functional) Pathologies such as osteoarthritis (OA) and rheumatoid arthritis (RA), and their radiologic features (e.g., joint space narrowing, osteophytes) Surgical approaches and components for Total Knee Arthroplasty (TKA): femoral and tibial implants, materials (cobalt chrome, titanium, polyethylene), and prosthetic design (PS vs. CR) Implant wear and failure causes, such as polyethylene wear, osteolysis, instability, and infection Surgical tools and techniques: cutting guides, alignment tools, imaging modalities (X-ray, MRI, CT), and degrees of motion Comparison of unilateral vs. total knee replacements, and options like CCK (Constrained Condylar Knee) Ideal for: Medical students in musculoskeletal or orthopedic rotations PA and NP students in surgical specialties Radiology and surgical tech trainees Engineering students studying biomedical implant design Professionals preparing for certification in orthopedic technology or joint replacement support roles This document provides a comprehensive review of clinical knowledge and technical understanding required for knee assessment and surgical planning, with clear, well-structured Q&A formatting.
