Abstract:
The aim of this study is to compare and correlate magnetic resonance imaging
(MRI) and arthroscopic findings in cases of ligament injuries. MRI is currently
available means of diagnosis in acute injured painful knee were clinical examination
is non conclusive. Because of high negative value and exclude arthroscopy. The
purpose of study was to correlate results of MRI in internal derangement of knee with
arthroscopy findings, so as to determine the efficacy of MRI in different intrarticular
knee injuries.
Aim & Objective of study
To observe sensitivity and specificity of MRI in detecting cruciate ligament tears,
confirmed subsequently with arthroscopy.
To observe the sensitivity and specificity of MRI in detecting meniscal tears.
To categorize discrepancies in finding of menisci and cruciate ligament between
arthroscopy and MRI.
Methods Of Collection Of Data
All patients who are clinically suspected of internal derangement of knee
presented in department of orthopedics will be evaluated with clinical history and
MR imaging in Radio diagnosis dept.
A surface coil is used, MRI will be performed using a 1.5 tesla MRI scanner
(Philips MRI System ).Axial, coronal & sagittal T1 ,T2 ,PD & STIR images will
be taken.
Strykararthroscope.

Result
Out of total 33 patients evaluated, most common injury were ACL and PCL injury
least Common. Medial meniscus injury is most common than lateral meniscus and
grade II & III common in both.MCL outnumbered LCL tear. Osseous lesion & joint
effusion were most common associated with injuries. On arthroscopy most of findings
correlated very well, however with ACL mid-substance & inferior surface of medial
meniscus showed negativepredictive value.
Conclusion
MRI is non invasive and reliable investigation for ligament pathologies, It
helps in accurate diagnosis of ligament injuries, there by helping in proper
management by conservative and surgical treatment.
However arthroscopy still remains gold standard for diagnosis and treatment
of the same. False negative cases have been reported in meniscal injuries. So, MRI
can be helpful to diagnose the knee injuries reducing there by invasive procedure and
assist further management.
