MR Imaging of Calcification of the Lateral Collateral Ligament of the Knee: A Rare Abnormality and a Cause of Lateral Knee Pain

Introduction: Lateral collateral ligament calcification is a rare cause of knee pain. There are only a handful of case reports, and the findings are usually incidental and asymptomatic. The exact mechanism for calcific deposit remains unclear. We present a case of symptomatic calcification within the lateral collateral ligament treated by surgical enucleation. Case presentation: A 52-year-old active woman presented with complaints of pain over the lateral aspect of the left knee of 6 months’ duration. Her pain was severe, aggravated on descending stairs but relieved on rest. Clinical examination revealed tenderness over the lateral aspect of the knee joint. Standard standing anterior-posterior radiograph of the left knee revealed a homogenous dense opacity adjacent to the lateral femoral condyle. Conclusion: Calcification within the lateral collateral ligament is rare and treatment is determined by whether the patient is symptomatic or not. If symptoms of the patient cannot be alleviated with a conservative approach, we recommend a surgical enucleation of the calcification, which in our case had good results.

Abstract Background Knee pain incidence is increasing among the community which has different multiple pathologies. Magnetic Resonance Imaging (MRI) is considered the gold standard imaging modality in diagnosing knee soft tissue injury. Ultrasound (US) is another modality which can be used in diagnosing soft tissue injury. Aim of the Work is to detect the reliability of US in diagnosing cases with knee pain as compared to MRI. Patients and Methods A prospective study was conducted on 20 patients with knee pain. They were referred from the Orthopedic and/or Rheumatology Department to Radiology department at Ain Shams University hospitals for MRI and US examination of the knee.The age group were from 19 to 59 years. Results In this study, 20 patients were examined with majority being males (75%). US was tested against MRI for different soft tissue pathologies.including knee effusion, meniscal pathology (tear, degeneration and extrusion), medial collateral ligament sprain, lateral collateral ligament sprain and Baker’s cyst. There was good agreement between US and MRI in most of these pathologies. US showed an overall sensitivity of 61.7% and specificity of 92.7% with accuracy of 86.9%. The overall PPV and NPV were 66.1% and 91.3% respectively. Conclusion Ultrasound can be considered a reliable screening imaging modality in cases of knee pain.

AbstractThe aim of this study was to report the outcome in a 6-year-old male English Setter dog that suffered a combination of divergent elbow dislocation and open distal ulnar fracture. This study is a case report. After surgical reduction in the elbow luxation, the dog was treated with the TightRope fixation system used as replacement of the lateral collateral ligament, a radioulnar positional screw, and external skeletal fixation. Removal of all implants was performed 3 months postoperatively. The 6-month follow-up visit found the dog without lameness, displaying normal activity, and with normal elbow range of motion and normal Campbell's test. Successful surgical management was achieved with good long-term results using TightRope, a positional screw, and an external skeletal fixator.

The Right

A 24-year-old right-handed man suffered right olecranon and lateral epicondylar fracture from high energy trauma. Fixation of olecranon was performed by a previous doctor. Three months after operation, he presented with limited range of motion (ROM) of the right elbow caused by malunion of the lateral epicondylar fracture and subluxation of the radiohumeral joint. Preoperative ROM of the right elbow was flexion 110° and extension −75°. Forearm rotation was pronation 85° and supination 65°. Fragment excision of the lateral epicondyle, which was 27 mm in length, and lateral collateral ligament repair using anchors were performed. Fourteen months postoperatively, contracture release of the elbow was performed. Twenty-four months postoperatively, radiograph of the elbow showed normal congruence without osteoarthritic changes and the ROM of the right elbow was flexion 120° and extension −35°. Forearm rotation was pronation 90° and supination 70°. In the surgical setting, in case of the size of the lateral epicondylar fragment is relatively large, the fragment should be fixed or lateral collateral ligament should be repaired when the instability of the elbow is found.
