Haemarthrosis of Knee Joint after Injury
- Rapid swelling of the knee after an injury
>a significant injury.
- Causes of Traumatic Haemarthrosis of Knee :- alone or any combination
-Joint Capsule tear
- Diagnosis:- H/O trauma plus a thorough examination gives an accurate diagnosis in most patients.
–Clinical Examination: Local Swelling with joint effusion, Tenderness, Painful movement, Examination/Tests for ligament laxity if possible (e.g. Drawer tests, Lachmann Test, Valgus/Varus stress test, Mc-Murray’s test, Pivot shift test etc)
–Examination under anaesthesia if clinical evaluation difficult due to pain
–Arthroscopic examination: invaluable in looking for the existence of other injuries with/without an associated ACL tear
–X-ray:- to diagnose fracture(s)
–MRI Examination:– beneficial to help diagnosing ligament/meniscus tears, osteochondral fractures, local soft tissue oedema etc.
-Aspiration of the fluid→ to help in reaching a diagnosis & to decrease pain.
- Initial Treatment:-Aspiration & Splinting of the knee, along with re-evaluation
- Adjuvant tests- including x-ray, & MRIs is beneficial.
- Although arthroscopic evaluation of the knee is not needed in every patient with an acute hemarthrosis, most of these patients eventually undergo arthroscopy to complete the diagnosis or as a means of early surgical intervention.
- Surgical Treatment:- to repair an injured structure
>depending on the patient’s age, activity level, amount of instability, & associated lesions.
- Routine arthroscopy:- indicated as a means to determine the correct treatment & not merely for diagnosis.
