Kneecap Resurfacing During Knee Replacement

updated by Cory Calendine, MD, Orthopaedic Surgeon

The decision to resurface the underside of the patella (patella) as part of total knee replacement may be influenced by a number of variables including surgeon’s preference, education, training, surgical technique, tradition and geographic location. Advocates for non-resurfacing or selectively resurfacing may claim no difference in patient reported outcomes, and that resurfacing is associated with increased risks such as extensor mechanism injury or malalignment, problems with the design of the patella component and technical issues intraoperatively.

New Patella Resurfacing Research

A new study recently published in the Journal of Orthopaedic Surgery and Research concluded that patella resurfacing and non-resurfacing often have similar patient-reported outcomes, but patella resurfacing is cost-effective and associated with a lower rate of re-operation compared to non-resurfacing. With improved patella prosthetic design and more precise computer-assisted knee replacement planning, Dr. Calendine chooses patella resurfacing for most knee replacement patients. The following video more accurately describes the process of patella resurfacing during knee replacement surgery.

Finger Dislocation Injuries and Treatment Options: A Comprehensive Guide

Finger dislocation injuries affecting the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints require immediate medical attention and appropriate treatment for optimal recovery outcomes. Treatment options range from closed reduction techniques using local anesthesia and manual realignment for simple dislocations, to surgical intervention for complex cases involving soft tissue interposition, associated fractures, or failed closed reduction attempts. The most common finger dislocations occur at the PIP joint, particularly in athletes participating in basketball and football, with an overall incidence of 11.1 per 100,000 person-years in the United States. Non-surgical treatment through closed reduction is successful for most simple dislocations, followed by immobilization with splinting or buddy taping for 3-6 weeks, while complex dislocations may require open reduction surgery and extended rehabilitation. Recovery typically involves progressive physical therapy focusing on range of motion exercises, strengthening programs, and functional activities to restore normal finger function, with most patients achieving full recovery within 6-8 weeks when proper treatment protocols are followed promptly after injury.

How Wound VAC Treatment Accelerates Healing

Struggling with a wound that won't heal properly? Negative pressure wound therapy (NPWT), also known as wound VAC therapy, uses controlled suction to accelerate healing and reduce complications. This advanced treatment creates an optimal environment for your body's natural repair process, resulting in 60% faster tissue formation and significantly reduced infection rates compared to traditional dressings. Ideal for surgical patients, diabetic foot ulcers, and chronic wounds, NPWT offers hope when standard care isn't enough. Learn how this proven technology works, who benefits most, and what to expect during treatment. Discover why thousands of patients have experienced faster recovery times and better outcomes with this revolutionary wound care approach.
