What is Hyperextended Knee?
Injuries to the knee stick are commonly seen in jock who participate in high intensity activities . These injuries cause inflammation and pain in the neck of the knee join . Hyperextended articulatio genus is one such exercise of these types of wound . Hyperextended knee is a condition where the knee ligaments get stretched beyond their normal range of motion.1
Pathophysiology of Hyperextended Knee
One of the most complex juncture in the physical structure is the knee joint . The knee joint juncture serves as a connection between the thigh ivory ( femur ) and shin bone ( tibia ) . The diminished bones present with tibia and the kneepan ( patella ) make up the knee joint . Tendons connect to the leg muscles and allow movement of the genu joint . The ligaments aid in joining the stifle bones and help oneself with the stability of knee joint . Knee joint is an example of a bicondylar synovial joint . flection and extension along with a little academic degree of medial and lateral rotary motion are the social movement which can be done with the knee joint .
In the case of a hyperextended knee , the knee joint ligament get stretched or deplumate beyond their capacity or limits . This cause tear or melodic phrase in the ligament . The damage incurred depends on the degree of the wound . The patient role may not be able-bodied to burthen bear on the affected leg when the stifle is recovering .
Causes of Hyperextended Knee
When the stifle joint is pushed or draw to bend backwards , then it causes hyperextended knee joint . This can pass after the patient role has had a wrong landing from after a start or precipitate from a ladder . Hyperextended knee is often discover in athletes who play fun which involve make sudden kink or turns and stopping like a shot . Some of the example of such sport are basketball , volleyball , football and gymnastic exercise . Vehicle accidentscan also make hyperextension of the stifle join after a unmediated force or blow to the human knee go to harm to genu ligament with a possiblekneecap disruption .
Signs & Symptoms of Hyperextended Knee
nuisance : Patient feel symptom of painfulness in the knee reefer after hyperextension of the knee joint.2Pain can be mild to severe and is dangerous where there is damage or tear to the ligament or other complex body part . hurting can be feel as a mild ache to a sharp painfulness in the back of the knee or it can be feel as a pinching pain in anterior part of the knee roast . At the fourth dimension of injury , patient also may learn a popping auditory sensation , which occurs as a outcome of overstretching of the ligament beyond their normal range of apparent motion .
Knee Instability : After a hyperextension knee injury , patient experiences symptom of instability in the knee joint and find as if their leg is “ throw out ” when walk or find it difficult to suffer on one ramification .
Reduced Mobility : Patient has decreased mobility with knee reach of motion , such as trouble in bending or roll out the ramification after a hyperextension injury . decrement in mobility can be from swelling around the knee , which limits the image of front of the articulation . The degree of reduced mobility also depends on the amount of hurt to the internal structures , such as the PCL , ACL , semilunar cartilage or popliteal ligament .
Swelling & Bruising : Patient can have immediate or delayed bruising and prominence of the knee and its palisade country . The bump and bruising can be balmy or hard . This is the body ’s method acting of responding to the accidental injury to the tissue .
Diagnosis of Hyperextended Knee
The chemical mechanism of the hyperextended knee accidental injury is significant to valuate which area of the knee joint is damage . strong-arm examen is conduct where the stirred knee articulatio is checked to look for any swelling or bruising in the area .
Palpation of the human knee and the surrounding muscles is done to look for tenderness . The doctor also perform range of movement movement to evaluate the severeness of the damage to the knee joint .
Imaging mental test such as x - irradiation or Magnetic Resonance Imaging ( MRI ) CAT scan aid in better visualization of the knee juncture . The x - beam helps in detection of any broken bone and MRI scan aid in assessing any injuries to the ligament and the surround knee structure .
How is Hyperextended Knee Treated?
If the damage to the knee joint is less , then conservative discourse , such as pain medications and residual is sufficient for recovery of hyperextended knee . In mild cases of hyperextended knee and with conservative treatment , recovery prison term is around 2 to 3 weeks .
Conservative Treatment of Hyperextended Knee
quietus : Patient with hyperextended stifle should take perfect rest and bar play sports for a while . high-pitched impact or high-pitched bodily function and inter-group communication sport should be avoided . meek range of motion exercise should be done . NSAIDs , such as naproxen and ibuprofen , aid in decreasing the pain in the neck and intumescency associated with hyperextended knee . crutch can be used to minimize weight bearing .
icing : Ice program to the affected articulatio genus joint for about 20 minutes every pair of hours helps in relieving pain and swelling associated with hyperextended knee . The ice should always be wrapped in a towel to prevent hide annoyance and should never be applied directly to the hide .
densification for Hyperextended Knee : pliant bandage or a compression wrapping can be used to lose weight extrusion and pain .
superlative : keep the affected leg kick upstairs above the level of the heart aid in reducing the extrusion caused due to Hyperextended knee . The leg can be send on a pillow when sleeping or sitting up .
Surgical Treatment of Hyperextended Knee
If the knee hyperextension causes bout or severance of the tendon , then surgery may be postulate to recompense it . One of the most mutual sinew injuries of the knee articulation is ACL or prior cruciate ligament rupture . These occur in extreme hyperextension of the knee articulatio . Injuries to the posterior cruciate ligament ( PCL ) and popliteal tendon can also occur with a hyperextended knee and take OR for fixture . If the campaign of hyperextended knee is a serious injury which causes damage to the semilunar cartilage , then also surgery may be call for for repair .
Rehabilitation & Recovery : After the surgical subprogram , the affected role will take to undergo renewal program to strengthen the stifle . Recovery from surgical process for hyperextended articulatio genus can take up to 9 month . Patient necessitate to come after the over rehabilitation program to improve the strength and tractability of the stifle muscle after the hyperextended knee wound .
