Analysis of Skier’s Knee

The rise in popularity of skiing has led to an increase in knee injuries. Knee injuries in skiers have a unique epidemiology and distinct mechanism. Understanding the exact mechanisms of knee injuries in skiers can help arthroscopic surgeons and related researchers treat and investigate skier’s knee injuries.

MRI of the Post-Operative Meniscus

Capturing an image of a postoperative meniscus can serve as a challenge, but magnetic resonance imaging (MRI) of the symptomatic knee after meniscal surgery is a valuable diagnostic study for both the menisci and the entire joint. For patients who had a partial meniscetomy of less than 25% may be evaluated by MRI, but for those who have a partial meniscectomy of greater than 25%, meniscal repair, a direct or indirect magnetic resonance arthrography (MRA) should be considered for evaluation. This study analyzes the decision between performing a direct (intra-articular) MRA, indirect (intravenous) MRA, or MRI to evaluate the meniscus after surgical repair.

Cost-Effectiveness of ACL Reconstruction

The purpose of this study is to analyze the cost-effectiveness of knee arthroscopy and ACL reconstruction. The study used a retrospective analysis of prospectively collected data from a single-surgeon, institutional review board-approved outcomes from a surgically treated knee athroscopy and ACL reconstruction. The outcome measured cost-effectiveness (cost of quality-adjusted life-year QALY) before and after surgery.

ACL Reconstruction Graft-Link Techniques

This study describes an anatomic, single-bundle, all inside anterior anterior cruciate ligament (ACL) graft-link technique using second-generation Flipcutter guide pins (Arthrex), which become retrograde drills, and second-generation cortical suspensory fixation devices with adjustable graft loop length: femoral TightRope (Arthrex) and tibial ACL Tight-Rope-Reverse Tension (Arthrex).

ACL Injuries in Patients Over 40

The purpose of this study was to determine the optimal treatment of an anterior cruciate ligament (ACL) tear in patients aged 40 years or older. The study evaluated 100 randomly selected individuals aged 40 years or older with regard to the following variables: age, gender, activity level, and visual analog scale regarding potential outcome preferences. The patients were divided into operative and non-operative potential outcomes.

Arthroscopic Knee Surgery Video

Part 1: Knee Positioning

Dr. Lubowitz discusses knee positioning prior to arthroscopy knee surgery. The specific knee injury will determine the exact positioning of the knee initially and throughout surgery.

 

)

 

Part 2: Surface Anatomy and Portal Placement

Dr. Lubowitz discusses the surface anatomy of the knee, and the portal placement. Understanding the anatomy of the knee externally is crucial to executing a successful arthroscopic knee surgery.

Part 3: Diagnostic Arthroscopy

Through the use of an arthroscopic camera, Dr. Lubowitz demonstrates the basic steps to knee arthroscopy, and gives educational insight on the anatomy of the knee.
