Prepared by Dr. Kayahan KARAYTUG Key Points Overview Total hip arthroplasty (THA) is a highly successful and cost-effective procedure that reliably improves pain, function, and quality of life in patients with debilitating hip pathology. The most common indication is hip osteoarthritis, followed by osteonecrosis, congenital/developmental disorders, inflammatory arthropathies, and post-traumatic degeneration. Anatomy and Biomechanics The…

Prepared by Dr. Kayahan KARAYTUG 1) Overview Robotic-assisted total hip arthroplasty (R-THA) uses computer planning and robotic guidance (most commonly robotic-arm + haptic boundary control) to improve the accuracy and reproducibility of component placement and restoration of hip biomechanics. Goal: optimize cup position, leg length, offset, and combined anteversion, while reducing variability compared with manual…
Prepared by Dr. Abdulkadir POLAT Overview Postoperative rehabilitation is essential after total knee arthroplasty (TKA) and total hip arthroplasty (THA) to restore mobility, improve strength, optimize range of motion (ROM), and reduce complications such as stiffness, thromboembolism, and functional decline. Protocols should be individualized based on patient factors, surgical approach, fixation, and intraoperative findings. A)…
Prepared by Dr. Abdulkadir POLAT Overview Implant design and material selection are fundamental determinants of longevity, stability, and functional outcomes in joint arthroplasty. Modern arthroplasty implants combine advanced biomaterials with refined design concepts to optimize fixation, minimize wear, and replicate native joint biomechanics. Basic Implant Materials Metals Cobalt–Chromium (Co–Cr) Alloys Titanium Alloys (Ti-6Al-4V) Tantalum and…
Prepared by Dr. Abdulkadir POLAT Overview Arthroplasty is a reconstructive surgical procedure performed to relieve pain, restore function, and improve quality of life in patients with end-stage joint disease or irreparable joint damage. Understanding core definitions, key indications, ideal patient features, and contraindications is essential for appropriate patient selection and risk reduction. Definitions Arthroplasty Surgical…
Prepared by Dr. Kayahan KARAYTUG Overview Robotic-assisted total knee arthroplasty (R-TKA) has gained widespread adoption in recent years, offering enhanced precision in implant positioning, alignment, and soft tissue management. By integrating advanced imaging, real-time intraoperative feedback, and data-driven planning, robotic systems aim to reproduce patient-specific knee anatomy while minimizing surgical variability and intraoperative trauma. Preoperative…
Prepared by Dr. Kayahan KARAYTUG Overview Preoperative digital templating in total knee arthroplasty (TKA) aims to estimate implant size and assist surgical planning. Unlike THA, its influence on postoperative biomechanics and clinical outcomes remains limited. Purpose of TKA Templating Digital templating in TKA is primarily used to: Accuracy of Digital Templating in TKA Studies demonstrate…
Prepared by Dr. Kayahan KARAYTUG Overview Preoperative digital templating is a cornerstone of modern total hip arthroplasty (THA). It enables accurate restoration of hip biomechanics, facilitates implant selection, and reduces intraoperative uncertainty. Despite advances in imaging, digital templating remains subject to technical and anatomical limitations. Objectives of THA Templating Digital templating in THA aims to:…
Prepared by Dr. Kayahan KARAYTUG Knee osteoarthritis is an increasingly prevalent condition, particularly among individuals over the age of 45. It significantly impairs quality of life and often necessitates medical or surgical treatment. While most patients with knee osteoarthritis present with degeneration involving all three compartments of the joint, approximately 20% exhibit isolated disease limited…
