Key Takeaway
Learn why knee surgery for ACL and meniscus tears may not automatically meet NY serious injury threshold. Expert legal analysis from Long Island personal injury lawyers.
When you’ve been injured in a motor vehicle accident on Long Island or in New York City, understanding whether your injuries meet the “serious injury threshold” can mean the difference between receiving compensation for your pain and suffering or being limited to no-fault benefits alone. This complex legal standard has evolved significantly over the years, and recent court decisions have shown that even surgical procedures may not automatically guarantee your case meets the threshold requirements.
The Evolving Landscape of New York’s Serious Injury Threshold
In New York State, the Insurance Law requires that personal injury claims arising from motor vehicle accidents demonstrate a “serious injury” as defined by statute before a plaintiff can step outside the no-fault system and pursue a tort claim for pain and suffering damages. This threshold has become increasingly challenging to meet, with insurance companies and defense attorneys scrutinizing every aspect of medical evidence.
Understanding the Current Standard
The buzz on the street over the last few years is that “surgery” is necessary to breach the serious injury threshold. On the no-fault side, this has translated into insurance carriers seeing many more surgery cases than in years past. It seems that surgery might not even save the threshold case as seen below:
Rodriguez v Grant, 2010 NY Slip Op 01780 (2d Dept. 2010)
“The affirmed magnetic resonance imaging report of Dr. Raymond Rizzuti merely revealed the existence of a tear of the anterior cruciate ligament and medial meniscus in the plaintiff’s left knee. A tear in tendons, as well as a tear in a ligament, is not evidence of a serious injury in the absence of objective evidence of the extent of the alleged physical limitations resulting from the injury and its duration.”
So does this relate to a service lacking medical reasonableness based upon the absence of objective evidence of the nature and extent of the underlying injury? This raises a really interesting question about what this means for certain no-fault medical necessity surgery cases.
The Medical Reality of ACL and Meniscus Injuries
Understanding ACL Tears
The anterior cruciate ligament (ACL) is one of four major ligaments in the knee that connect the femur to the tibia. ACL tears are among the most common and serious knee injuries, particularly for individuals who participate in sports or experience trauma from motor vehicle accidents. In New York’s bustling metropolitan areas, from Manhattan to Nassau County, emergency rooms see hundreds of these injuries annually from car accidents alone.
ACL tears are typically classified into three grades:
- Grade 1: Minor stretching with small tears in the ligament fibers
- Grade 2: Partial tear of the ACL with moderate stretching
- Grade 3: Complete tear or rupture of the ACL
Meniscus Tear Complications
The meniscus acts as a cushion between your thighbone and shinbone, consisting of two wedge-shaped pieces of cartilage. When torn in conjunction with an ACL injury, the complexity of the knee damage increases significantly. Meniscus tears can be:
- Traumatic tears: Resulting from acute injury like a car accident
- Degenerative tears: Related to aging and wear
- Complex tears: Involving multiple areas or types of damage
Why Surgery Alone May Not Be Enough for Serious Injury Cases
The Rodriguez decision highlighted a critical issue facing personal injury attorneys and their clients throughout Long Island and New York City: the mere existence of structural damage and subsequent surgical intervention does not automatically establish serious injury under New York law.
The Objective Evidence Requirement
New York courts require objective evidence of both the extent and duration of physical limitations. This means plaintiffs must demonstrate:
- Measurable functional limitations: Range of motion restrictions, strength deficits, or gait abnormalities
- Duration of limitations: Evidence that restrictions persisted for a significant period
- Causal relationship: Clear connection between the accident and the ongoing limitations
- Professional documentation: Consistent medical records from treating physicians

Legal Update (February 2026): Since this post’s publication in 2010, New York courts have continued to refine the serious injury threshold standards, particularly regarding surgical procedures and ACL/meniscus injuries. The legal landscape surrounding Insurance Law § 5102(d) has evolved through subsequent appellate decisions that may have modified how courts evaluate the sufficiency of medical evidence for knee surgeries. Practitioners should verify current case law and threshold requirements, as judicial interpretations of what constitutes adequate proof of serious injury have continued to develop over the past sixteen years.
