Partial Meniscectomy Versus Nonoperative Management in Meniscal Tear With OA: A Randomized Controlled Trial (MeTeOR)
There are two cartilage structures, called menisci, in each knee joint. A torn meniscus can
be caused by a traumatic injury or aging-related degeneration. Osteoarthritis (OA) is a type
of arthritis that is caused by the breakdown and eventual loss of another type of cartilage
that covers the end of bones within a joint. In people who have knee OA, a meniscal tear can
easily lead to disability. This study will compare the effectiveness of two recommended
treatments, surgery and physical therapy, for people with a torn meniscus and knee OA.

OA is the most common form of arthritis in the United States. Symptoms of knee OA include
pain in and around the knee that typically worsens with weight-bearing activities, morning
stiffness, and tenderness. A person with OA who experiences a torn meniscus--a cartilage
structure within the knee that provides stability and proper weight distribution--is
especially at risk for disability. Past studies have shown that arthroscopic partial
meniscectomy (APM), a type of knee surgery, usually relieves symptoms and improves function
in people suffering from a meniscal tear. However, the success of APM is more variable among
people with already existing OA. Clinicians are also uncertain about the short- and
long-term benefits, drawbacks, and indications for APM in people with OA and meniscal tears.
The purpose of this study is to compare the effectiveness of two treatments, APM surgery and
standard physical therapy, for people with OA and a torn meniscus.
This study will last 5 years. At the initial study visit, participants will be randomly
assigned to one of two groups.
- Group 1 participants will undergo APM surgery at a time that is convenient for the
participant and surgeon. After surgery, participants will be referred for
rehabilitative physical therapy to regain strength and flexibility of the knee. For
participants who choose to do physical therapy, the duration of treatment will depend
on individual progress.
- Group 2 participants will receive standard physical therapy to increase strength and
flexibility of the knee. This will include one to three weekly exercise sessions over
an 8-week period.
The study consists of up to 3 visits to the center:
- Visit 1, the enrollment visit: sign the consent form, fill out a questionnaire, have a
physical examination of the knee and find out your treatment group (surgery or physical
therapy
- Visit 2, at 3 months after enrollment: Fill out a questionnaire and have a physical
examination of the knee
- Visit 3, at 18 months: Fill out a questionnaire, have an MRI of the knee (if eligible)
and xrays of both knees
Telephone calls: During the first 3 months of the study, all participants will receive
check-up phone calls every 2 weeks, followed by quarterly phone calls for the initial 2
years in the study
Questionnaires: Participants will also complete mailed questionnaires at 6 months, and 1, 2,
2.5, 3, 3.5, 4, 4.5 and 5 years after enrollment. The questionnaires will include questions
about knee pain, ability to walk, recreational activities, general health, and satisfaction
with with treatment.

plain radiographic evidence of osteophyte formation or joint space narrowing
- Evidence of a meniscal tear (tear extending to surface of meniscus) on a knee MRI
- Willingness to undergo random assignment and sign an informed consent
Exclusion Criteria:
- Chronically locked knee
- Kellgren-Lawrence Grade IV status, indicating advanced OA and usually the need for
total knee replacement

pyrophosphate dihydrate [CPPD] crystals in one or more joints that eventually result
in damage to the affected joints) AND acute symptomatic pseudogout

lupus erythematosus, gout, pseudogout)
