Medial knee injury | inner knee disorder

Medial knee injury

The injury of the medial knee type is a common form of knee injuries that are present  on the knee  inner part . knee   complexly  of  medial  ligaments composed  of three type  MCL. A sum   of these three is   collectively called MCL.

Medial collateral ligament

The average collateral tendon (MCL) interfaces the bones within the thigh bone and lower leg. The MCL runs along the inside of the knee while the horizontal indemnity tendon  runs all along the beyond of the lap. Both these two tendons together with others, offer assistance to withhold the knee in place.

Ligaments for the most part comprise of thick connective tissue. A sprain stretched these tendons, which can end up free afterward causing serious damage. A tear may be a numerous serious damage that breaks the tendon in two.

When a few tears the MCL, it may not tighten the knee as safely. MCL wounds happen amid affiliation sports. Coordinate contact to the exterior of the knee amid a contact can thrust the knee one side .

This puts a tall constraint on the MCL, which can tear. The muscles are contracting whereas running and turning can too put a tall push on the tendon to sprain it.

A MCL harm is all tears of the tendon inside the knee MCL (average collateral tendon) could be a band of tissues that run at the side inward circumference of the knee.

They connect your shin and thigh bones to keep your knee adjusted and working legitimate when moving . When your MCL isn’t legitimate working your knee can over-extend itself or attach too far in a side that’s not gathered to twist .

But on the off chance that your damage is serious, you will have to have surgery. The MCL is displayed within the knee center side. The average collateral tendon is exceptionally imperative to keep up the soundness of the knee joint.

The ligament is  made up of  many     of collagen   fibers  and  also composed of less  numbers of elastic fibers. It protects  the knee from any kind of damage  and external  force  and  also prevents the medial side  of the joint  from  any other  kind of stress. 

The (MCL) medial knee collateral ligament injury  occurs  after the   knee  outside   and   upper leg.  The  foot is  in direct  contact with the ground  and they cannot  walk  or  move. We understand the medial knee structure and function and internal organs   by physical test  and  treatment  of knee injury .

Knee Components

  • bone
  • tendon
  • muscles
  • sinews

Various kinds of lap wounds

At the lap satisfying beat position the femur is described as hip bone or thigh bone. The foot of the knee joint is made up of tibia and shinbone. This foot is covered and protected by kneecap which is called a patella. These bones are connected by cartilage tissue; this tissue prevents the bone from moving apart during the movement.

 Some other tissue called ligament also join these bones and help in movement the bind these bones like a rope.

Hairline Fracture: Some of the bone in over the leptin can be broken. The foremost common fractured jaw bone within the common is the patella kneecap. Tall affects injury such a drop or vehicle mishap, Reasons for the most part knee break.

Frontal cruciate tendon damages 

The front cruciate tendon (ACL) run askew set down the face of the lap, Giving basic solidness to the mutual. Wounds to the ACL tin be genuine and required operation. ACL wounds are reviewed on a range from 1 to 3. A review 1 wrench is mellow harm to the ACL whereas a review 3 alludes to a total tear.

Athletes who take an interest in contact wear such as football, frequently harm their ACL. In any case, making contact with sports activities is not as it were because of this grievance. When very abruptly the direction of motion is changed the muscles inside the knee joint are torn causing severe pain and make it impossible to move.


When the perfect alignment or arrangement of lap jaws is disturbed the lap moves apart from each other. Lap disengagement, one or further of the bone may creep out of put. Auxiliary variations from the norm or injuries, counting car mishap, collapses, and communication wear, can reason a lap interruption.

Meniscal scratches

While community groups allude to damaged gristle in lap, they are likely discussing almost menisci scratch. The menisci are two overcooked wedges of tendon among the thigh bone and shinbone. These fragments of tendon can tears all of a sudden amid wearing exercises. They too tear gradually due to aging.

Through an abruptly meniscus wrench, current might be listened to or understood in the lap. After beginning damage, torment, swelling, and snugness may increment over the following few days.


Bursitis is little watery-crammed bladders that pad the lap joint and permit the ligament and tendon to glide effortlessly across the cooperative. These pouches can swell and end up aroused with abuse or rehashed weight from the knee.

It is commonly called or termed as bursitis. In most cases in the self-care treatment bursitis which is not genuine is used. In some cases or treatment antibiotics are used as a cure. It involves a needle which draws back most of the fluid to use.


The patella tendinitis is  group or cluster of lap or tendinitis.  This is often an damage to the ligament that interface the lap cap to the shinbone. The patella’s ligament works with the facade of the thigh to amplify the lap so an individual can scamper, bounce, and execute other bodily events.

Often alluded to as an athlete lab, tendinitis is widespread along with competitors who habitually bounce. In any case, any bodily dynamic individual can be at chance of creating tendinitis.

Ligament Damage

Ligament are delicate tissues that interface the physiques to the skeletons. In lap, a familiar ligament to survive harm is the patellas. It isn’t unprecedented for a competitor or intermediate-age individual to include bodily exercises to damage or overextend the ligament. Coordinate affect is since a drop or beat night too caused a sprain within the sinew

Indemnity tendon damages

Collateral tendons interface the thigh bone to the shinbone. Harm to these tendons may be a commonplace issue for competitors, especially persons included in make contact sport. Warranty tendon scratches happen due to an accident with an additional person.

Iliotibial orchestra disorder

Iliotibial group disorder is frequently included as an extended remote runner. It is triggered while the Iliotibial ensemble, which is found on the exterior of the lap, shines alongside the exterior of the lap joint. Naturally, the torment begin sour as minimal aggravation. It can continuously build to the moment where a candidate must halt stretching for a time to sublet the Iliotibial ensemble repairs.

Subsequent cruciate tendon damages

Behind the knee joint there is the cruciate tendon. The subsequent or back tendon joins the hip bone or thigh bone and shin bone together. This binds these bones together during movement and stabilizes during motion.

When the knee joint is bent during the motion it can damage the back cruciate tendon. The chance of injury is increased when someone falls when its leg is bent or knee joint is in its bent position causing damage to this tendon.


An MCL tear causing torment on the inward side of the knee. Tearing the MCL are likely to caused numerous extreme torment which spraining the tendon .A contaminated individual may feel a popping sound at the time of the wounds.

This was the voice of the MCL tearing. a individual was feel to  take note swelling within the harmed range which may never happened quickly. Swelling can spread to the other side of the knee joint wounds within the days after the damage.

The knee may feel stuffy and players have trouble rectifying the leg or bowing their knee.The may too finding climbed the stairs or sitting in a chair challenged as they specified them to bowing their knee. The torn MCL can influencing the adjusted of the knee.

A individual can feel as in the event that their knee might give way or that their knee cap feel misplaced .It was conceivable to harmed or crush other tendons at the same time as the MCL .In the event that a blow to the knee is serious cause these harm ,

  • The LCL on the front or higher of the knees
  • The front cruciate tendon (ACL ), which can attach bone in the  thigh and  posterior limb at the anterior  side of  the lap.

These are caused discomfort in the portions of  the lap. It will take away lengthier damage to rebuild if a person damaged many sinews.


When your external knee is exceptionally difficult, The MCL, which runs along your inward knee, can stretch out sufficiently to strain or tear.

Sportsmen those playing football, hockey, and other sports the players affect other competitors with tall drives may wound their MCL within the way. You extend or tear your MCL in case your knee is suddenly pushed to the side, or in the event that it turns or twists out as well.

Anatomy and function

The knee is pivot joint; these are dependable for weight-carry and development. It contains bones, meniscus, tendons, and tendons.

The lap structure contains many of   purposes:

  • help the deceased in an uplift situation not including the needed  for weights to working
  • supports to bend and uplift  the corpse
  • supports balanced
  • play-acts as a jerk absorber
  • permits twists of the legs
  • make moving much effective
  • facilitates push the groupahead or toward

Beneath it can explain the important components of lap internal structure .

Jaw Bones

Knee is made up of two types of bones: patella and tibia. These bones are kept in place by the knee joint at the front of the knee present the Patella which is small in size having 3  corner structure and present between the quadriceps muscles these bonds are surrounded by very large number of carriage issues it provide n very good force

Cartilage Tissue:

The knee is composed of two types of cartilage.

 One of them is called meniscus. It is spherical in shape. They form a cushion around the knee and decrease the amount of shock during the movement. It also helps in decreasing the friction between the bones present in the knee during movement. A nerve is connected with the meniscus which help in right balance and proper alignment with respect to the weight division between the bones with the femur

The meniscus is of two types one is called medial and other is call lateral the medial is is present internal to knee and the lateral is preset on the outer region of the knee

The second type of cartilage present in the knee is called Articular Cartilage and it also can be injured.

This cartilage is located on the bone femur below which tibia is present upper patella bone is present the cartilage help the bone to move continuously without rubbing or friction over one another


Two bones are connected with the special type of tissue which are called ligaments. They are thick Silk-like and long strong thread of connective tissue providing balance and protecting the bones. There are 4 types of ligaments which are listed here.


These very strong and delicate present all over the knee It is just like the tendon but their function is to two bones together while tendon joins the muscle with the bone The largest ligament tissue is present on the upper area of the knee call patellar ligament it is extended till the thigh bone and attached to the quadriceps of the thigh it function is to protect the knee cap

Brute Force

This is not a part of the knee joint but its function is to stabilize and connect the knee with nerves

It composed of 4 quadriceps muscles and three types of Hamstring muscles the quadriceps muscles make the knee straight while the three hamstring muscles stabilize

Collaborative pill

The lab place in the knee is surrounded by an empty space pouch which is filled with a friction reducing liquid called Synovial it also help in the nourishment of the knee

 Connection of Tibia and femur with the help of ligaments in following ways        

Anterior cruciate ligament (ACL)

The ACL ligament  in the knee is present  in the middle  which controls   the forward movement and circulation  of tibia.


The ligament of pcl  present in the knee center controls tibia backward movement.


The ligament  of MCL makes the inner part of the knee stable.


This gives a higher stability knee outer part.

Biomechanical function of knee


The knee joint also has a biomechanical function which functions as a permission gate as it flexes and rotates at the same time by providing stability in daily life. Knee also allows the locomotion of muscle movement with minimum use of energy.

The sMCl function is to connect femur with tibia  present posterior to medial epicondyle  and has two sections . one of the tibial sections which connect the soft type of tissue the second tibial section attaches directly to the tibia which is 6cm long with a part distal  to the joint line.

The dMCL originates from femur which is one cm long to distal part with sMCL origin. The dMCL which  connects directly with a part medial meniscus which can add further divided into meniscotibial ligament and into the meniscofemoral part.

The ligament part is longer than that of femoral part of meniscofemoral .The meniscotibial ligament will stabilize the internal interaction .

sMCL oblique portion (POL) has three main parts

  • Central
  • Superficial
  • Capscular

The central part is the thickest part which arises from the semimembranosus tendon  which further connects  distal and inferior portions. POL is not alone structure and has major function to stabilize internal rotation of knee.

Tendons and muscle

Tendons muscle of thigh with kneecap and makes power straight  to knee. It hold patella in femur part which is patellofemoral grave .

The patellar connect kneecap with tibia .Adductor tendon is excellent structure which got rarely injured .The medial gastrocnemius tendon arrive from proximal gastrocnemius tubercle which is present posterior side.


Your doctor yearns for want to know how you come to be harmed and what is your  feeling  and getting around  since the injuries.

He or she checked to see what is harming your MCL and how severely it’s been compressed or torn. They may push on the inward side of your knee to see how to adjust or misplace the joint. They may moreover squeeze on the external parts of your knee when the leg is both bowed and straight to check on how the issue is so difficult.

  • The  doctor also need several imaging test of your injuries   lap
  • An MRI  deal  report can show  MCL damage , so the  doctor wants to know how hard pain your straining or rip is.
  • X-ray. they want to show you their MCL, but it can show whether you have cracked  bones .

Push X-ray. In spite of the fact that X-rays appear on bones and not delicate tissues as compared to tendons, The specialist is able to tell what or not MCL is torn with a push X-ray. you’ll attempt to unwind, and after that your specialist the X-ray will tenderly drag on the MCL side of your knee to see in the event that it opens up more than it ought to .

On the off chance that the picture appears an enormous space there centers the shin and thigh bones. At that point the joint is misplaced, and your MCL is torn.

Physical exam

Physical examination can be seen directly with a visual inspection which is an outer sign of the trauma. The injury of one versus the other has complications to healing, so a proper place of injury is beneficial.

The following technique and test will add helpful

Valgus stress at 0 to 20

This test has direct stress to the medial knee by the injury mechanisms. Valgus test done by the patient supine .The knee will add at angle of 20with flexion .The doctor uses their thigh at knee and applies valgus force.

Dial test

This test is done with patient supine at an angle of 30degree.  Thigh of the patient will stabilize and the foot rotates. The doctor then watches the tibial of the affected knee. This is an easy process.

 Treatment medial knee injury

Treatment will vary depending upon the patient’s knee injuries. They are graded differently by grade 1-3 injuries. Acute kinds of injuries involve the medial side of injury. Chronic grades include the surgery of the knee. The treatment will also be done by the Nonoperative and operative treatment.

All knee harm ought to be elevated by a specialist as conceivable. Essential treatment for commonly knee wounds include rest, ice, rise, and an over-the-anti torment calming by such as Ibuprofen .

 It is additionally vital to start reinforce and extend works out 24-48 hours after brief wounds, or as prompted by a specialist. They ought to be a step by step returned to typical exercises. The damage is repaired by ACl tear in the surgery.

Bodily Psychotherapy

It regularly demonstrates to help an individual’s recouping to reduce the pain along length during the movement. This therapy also takes place in the home extending its limits. Without any satisfactory restoration, individuals will tend to feel the pain and difficulty to move hence this therapy will restore the movement.

Damage avoidance

The following guidelines help in protecting commonly  knee damages:

  • Warm-hearted up by marching and stretching  lightly  prior to and later playing sports events.
  • Stay the hind leg physiques more robust by use  stairways
  • Horse-riding a resting trail bike
  • Works  out with any weight.
  • Preserve a fit weight to avoid  adding force  on the laps.
  • Always wearing a seat belt.
  • Using knee defenses in sports where lapscan get damaged.
