What A MENISCUS TEAR? CAN I GET MENISCUS TEAR TREATMENT IN MELBOURNE?
Our knees have both a lateral and a medial meniscus. It is a fibrocartilage layer that separates your femur (thigh) from your tibia (shin).
They are pivotal to providing rotational stability to your knee and act as a shock absorber during motion, helping to disperse compressive forces throughout the knee.
Meniscus tears come in many variations, and can happen to both medial and lateral meniscus.
Medial is more common, though lateral tends to be slower to settle. The majority of torn meniscus injuries improve with graded rest, tailored physio for a meniscus tear and a planned return to sport or activity.
Occasionally, surgical intervention is required, though this is far less common these days for degenerative tears.
How do MENISCUS INJURIES occur?
Meniscus injuries can be caused by many, and sometimes poorly understood, mechanisms. Typically, an acute, traumatic tear results from a twisting, cutting or fast change of direction motion.
Degenerational tears can occur with simple turning, golf swings, getting out of the car, kneeling or deep squatting. These are motions people would have done millions of times, then suddenly experience pain.
We simply don't have all the answers as to why these tears occur.
WHAT ARE THE Signs and symptoms of a torn meniscus.
Pain along the inside or outside of the knee joint is common, plus or minus joint swelling.
Usually, a history of twisting with a slightly flexed knee is noted. Occasionally people experience locking, collapsing or giving way sensations.
Your physiotherapist has multiple clinical tests to determine a meniscal tear, including Duck Walk, McMurrays, Effusion Sweep and Joint Line Palpation tests.
Do you need scans for Meniscal Tears?
Generally, no, and if you do it may be after 6 weeks of conservative rehabilitation. For an acute traumatic injury, scans may be ordered at initial consultation. X-rays don't show meniscal tissue. MRIs do, though this isn't a first treatment option, as scan results don't necessarily correlate with pain or functional levels.
You should never diagnose or plan your rehabilitation based just on an image.
You need to factor in your functional status and rehabilitation goals at all times. A study by Zanetti et al (2003) showed that 36% of non-symptomatic knees had a tear on MRI (age 18-73), without any symptoms.
What should you do About a meniscal tear?
First step, rest from the aggravating activity and seek medical opinion. Your local knee physiotherapist will be able to perform the above mentioned tests and give you a clear idea on recovery plan or whether surgery is required. Usually, a standard meniscal tear will take 6-8 weeks to settle with conservative management. This can vary quite widely.
Should You Have Surgery for a Meniscus tear?
Generally not. Your knee physiotherapist will assist you in making this decision.
Main consideration needs to be around whether your meniscal injury is degenerative or acute. A recent systematic review of the medial research literature by Kahn et al (2014) showed no evidence for surgical intervention in degenerative meniscal tears versus conservative rehabilitation management.
For an acute meniscal tear, with an inability to extend or move the knee, surgery may be required and has a high success rate. Rarely, will you need to rush into making a decision.
