With the uptick in surgeries that are taking place in no-fault practice, the question that every claims representative or defense attorney evaluating these types of cases needs to ask is: “was this injury causally related to the accident?”
As a Plaintiff’s attorney, the question you need to ask, in response to this, is how do you at least raise a triable issue of fact when faced with what should be the inevitable summary judgment motion from the defense attorney.
This is a case from the First Department, where in my opinion, they lay out how a plaintiff needs to address this type of defense.

While defendant’s experts found that plaintiff’s injuries were degenerative, plaintiff’s doctors were unanimous in concluding that the subject accident was the sole competent producing cause of plaintiff’s knee injuries, based upon (1) their individual examinations; (2) MRI results; and (3) the necessity of surgery to repair a tear in the medial meniscus, a partial tear of the anterior cruciate ligament, chondromalacia, synovitis, and fibrosis (see Pommells v Perez, 4 NY3d 566 ; Colon v Bernabe, 65 AD3d 969, 970 ). It also bears noting that plaintiff was 37 years old when he was hit on his right side by defendant’s taxi, he had no prior knee problems or injuries to his right leg, and his right knee surgery took place within four months of the accident.”

Legal Context
Why This Matters for Your Case
New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.
Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.
About This Topic
Causation in New York Personal Injury & No-Fault Law
Causation — proving that the defendant's negligence or the accident caused the plaintiff's injuries — is an essential element of every personal injury and no-fault claim. New York courts distinguish between proximate cause, intervening causes, and pre-existing conditions that may have been aggravated by an accident. The legal standards for establishing causation through medical evidence and the defenses available to challenge causal connection are analyzed in depth across these articles.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
