What Is A Meniscus?

The meniscus is a piece a cartilage that sits in the knee joint betwixt the bones of the thigh (femur) and the shin (tibia). Its made of a like type of cartilage found in our ears (fibrocartilage) and is just every bit sturdy.

The meniscus acts as a shock absorber (suspension) in the knee joint and provides some stability too. When the meniscus is non working properly or has been injured or removed, more daze is transferred to the bones in the genu (and the smoothen cartilage that lines those bones). This results in increased wear and tear and eventually osteoarthritis. People who accept had meniscal surgery are 14 times more than likely to develop osteoarthritis than people with a meniscus.

Key POINTS:

The meniscus has no nerve supply. This ways you can cut into the meniscus with a scissors and feel NO pain
However, meniscal injuries can effect in pulling on the lining of the articulatio genus (capsule) which is extremely sensitive to pain. The injury also stimulates inflammation which causes pain and swelling

Will My Meniscus Heal On Its Own?

The meniscus has some blood vessels at the very outer edge (come across diagram). This blood supply (red zone) slowly fades away once nosotros are older than 30 years erstwhile. For tissues to heal when they are injured they demand to have a blood supply. So, most meniscal injuries have express healing potential unless they are at the very outer edge and the patient is less than thirty years old.

What Symptoms Does A Meniscal Tear Give You lot?

Usually people will develop pain on the side of their knee (either the medial/inner or lateral/outer)
At that place may exist an associated clicking/communicable feeling
The pain can come up on suddenly with a specific movement only in older people the pain normally comes on slowly with fourth dimension
Some swelling of the human knee may exist present
The hurting is irritated past twisting movements and squatting downward
Major meniscal tears tin can lock your knee (stop information technology from straightening), these are known equally bucket handle tears

How Does A Meniscus Get Injured?

A meniscal tear seen during arthroscopic surgery

The meniscus is usually injured when someone has a bent knee and changes direction. Oftentimes the movement that injures the meniscus is no different to whatever number of movements you would make throughout a 24-hour interval such as rise out of a chair and pivoting.

It is rarer to have meniscal injuries when y'all are less than 30 years one-time as the meniscus is salubrious and stiff. As we age, meniscal tears get increasingly mutual equally the meniscus wears down and erodes with time. For this reason, older people often don't observe a specific moment when they injure their meniscus as it usually just slowly fails and becomes frayed. Conversely, younger people do often written report a specific incident where they hurt their knee joint as the force required to tear a young potent meniscus is much higher. In the older knee, meniscal tears are now being considered as part of osteoarthritis instead of a dissever injury needing specific handling.

Cardinal FACTS:

i in 3 people over fifty years old take a meniscal tear (expected degenerative alter)
20% of people over 50 years old with articulatio genus hurting take a meniscal tear
25% of people over fifty years onetime WITHOUT knee pain have a meniscal tear!

KEY DIAGNOSTIC Point:

SEEING A MENISCAL TEAR ON MRI DOES Not CONFIRM THE MENISCUS Equally THE SOURCE OF Pain

Does a Meniscus Tear Demand Surgery?

The only meniscal tears that demand surgery are those that can be repaired, or tears that requite persistent pain despite good quality non-operative care. In general, if you are over 30 years old the meniscus has reduced healing potential and is less likely to be repaired equally the blood supply to your meniscus starts to diminish.

If you have a tear of the meniscus in or nearly the blood supply, the meniscus may heal if surgical stitches hold it together whilst it heals (similar to how skin stitches simply concur the skin together whist waiting for the pare to heal). The stitches themselves are non very potent so if the meniscus injury is in an area without claret supply (white zone), the stitches will not repair the meniscus past themselves.

A specific type of meniscal tear called a 'bucket handle tear' can occur and cause your human knee to be locked (cannot fully straighten your knee). In all cases of a locked knee joint further medical cess is required urgently as in that location are several causes of a locked knee. If yous have a bucket handle meniscal tear you will need urgent surgical referral for either repair or fractional meniscectomy. Non-operative treatment is not an option for bucket handle meniscal tears.

Can Your Meniscal Tear Heal On Its Own?

Small-scale meniscal tears in the 'scarlet zone' in younger people may heal without surgery though. If you accept a tear of the meniscus away from the blood supply information technology is unlikely to heal on its own. However, even if your meniscal tear is outside of the 'red zone' or you lot are older than xxx, y'all can withal treat your pain successfully in a few means;

What Is The All-time Treatment For Meniscal Tears?

A big number of scientific studies involving thousands of patients take improved our understanding of meniscus treatment options.

Meniscal Surgery

For many years the almost frequent handling for meniscal tears was to cut out the part of the meniscus that was torn via keyhole surgery (known as arthroscopic partial meniscectomy) to attempt and forbid ongoing inflammation within the knee. By and big, this surgery was successful for treating human knee pain, but it was recognized that the risk of developing human knee problems later in life was increased one time yous had had a partial meniscectomy. A group of patients were seen to have poor outcomes subsequently partial meniscectomy surgery. These patients already had osteoarthritis in the knee and once the meniscus (intermission) had been removed, their pain increased. Patients with this response have few handling options available beyond a total genu replacement which is undesirable for nigh until absolutely necessary. Therefore, partial meniscectomies in people with osteoarthritis is not recommended.

An upshot with meniscal surgery is the amount of meniscus that needs to be removed. Successful surgery requires the meniscus to be resected dorsum to a stable base. Although the tear in the meniscus may be small, its effect on meniscal function is potentially big. The meniscus is fabricated up of fibres the run all the way through it from the front to the dorsum – like multiple washing lines stacked together to make a strong unit. A small tear in the meniscus is like snipping the washing lines in half – the injury to the fibre is quite localized but the unabridged fibre is defunctioned. Surgery tries to remove all of the injured fibres working on the theory that this volition reduce the number of re-tears that occur. Unfortunately, this ways a modest tear however results in a pregnant amount of meniscus being removed and resecting equally little as xv-35% of the meniscus tin issue in forces increasing in the genu past up to 300%. This later stresses the bones and the smoothen cartilage that lines them and results in early osteoarthritis in many people.

Subsequent scientific studies accept establish that having a partial meniscectomy did not meliorate people'southward pain any more than than did 'sham (false) surgery'. In these studies patients were anaesthetized (put to slumber) and the knee was explored via keyhole surgery. In one group of patients the meniscus was not touched. The other group had the meniscus surgery. None of the patients knew if they had the real or simulated performance. At all follow up points after the operation, there was no difference in patients' hurting scores whether they had the faux surgery or the partial meniscectomy.

The results from the sham surgery prompted further enquiry into non-operative treatments such as anti-inflammatories, injections and rehabilitation for meniscal injuries.

Meniscal Surgery Summary

Surgery helps pain but is not more successful than fake surgery, anti-inflammatories or exercise in most people
Partial meniscectomy affects function of the knee and will speed upward the onset of degenerative osteoarthritis

Non-Operative Treatment For Meniscus Injuries

We now know that the bulk of patients have at to the lowest degree as good outcomes (reduction of hurting and improved function) if they perform a physiotherapist supervised practise rehabilitation program for a few months instead of having surgery. Not all physiotherapy is the same and information technology is important that the physiotherapist that guides your rehab performs a thorough examination of your knees, understands your specific needs and tailors your do program accordingly.

In some cases, the pain in the knee is likewise severe to perform the rehab exercises or too swollen to allow the muscles around the articulatio genus to piece of work effectively. In these circumstances, treatment with either anti-inflammatory tablets (guided by a doctor) or an injection into the knee (preferably under ultrasound guidance) are recommended. These treatments can settle your pain and swelling sufficiently to allow y'all to perform rehabilitation work.

Although the majority of patients volition not demand surgery for their meniscus injury, some people volition nonetheless take pain after performing rehab. When this is the case, surgery for the meniscus should be considered.

What is a Discoid Meniscus?

Children and adolescents with lateral human knee pain volition often take an injury to a discoid meniscus. A discoid meniscus is something some people are born with and information technology is a meniscus that is circular rather than moon-shaped. A discoid meniscus is vulnerable to tearing only resecting the excessively large fragment of a discoid meniscus does not seem to take any adverse effects as the patient is left with a normal looking moon-shaped meniscus.

What Is A Meniscal Root Avulsion?

Occasionally people tin rip the meniscus off the os where it attaches. The injury mechanism is no different to other meniscal tears, but the resulting pain and loss of function is astringent. In that location is frequently significant posterior knee pain and difficulty with weight bearing. Swelling may not exist significant. Occasionally these can be repaired through a specific surgical technique. If information technology cannot be repaired and in that location is underlying osteoarthritis present, the injury tin can be devastating. This is so managed equally a severely painful osteoarthritic knee and can effect in a total human knee replacement if non-operative treatments are unsuccessful.

New Applied science On The Horizon?

In the United States, in that location is ongoing research in to the utilize of meniscal allograft surgery where a meniscus donated from a deceased person is used to supplant the injured meniscus. The results for this procedure are promising only it is not available in Australia and is unlikely to be a treatment option in the virtually future due to a lack of availability of donor menisci.

SUMMARY OF MENISCAL Problems

Meniscal tears are common in middle-aged people and may not be the cause of knee pain
Symptomatic meniscal tears should exist treated with not-operative treatments (supervised physiotherapy, anti-inflammatories, injection therapy) for a few months before considering any surgical intervention
Surgery is a skilful option for hurting that persists despite expert quality not-operative handling
Although surgery may aid pain it will impact knee role and speed up osteoarthritis
The only tears that tin exist repaired are those in the outer edge of the meniscus, usually in people less than 30 years quondam
If y'all have a locked knee (can't fully straighten) you need to come across a medico for urgent assessment

The Sports Medicine Physicians and Sports Physiotherapists at Newcastle Sports Medicine are experts in assessing and treating all knee issues including meniscal injuries. If yous would like your human knee assessed or treated please call (02) 4910 0805 to make an appointment.
