Summary
Systemic lupus erythematosus (SLE) patients experiencing patellar tendon rupture require prompt emergency department diagnosis and treatment. Early intervention is crucial for optimal recovery and minimizing long-term knee dysfunction.
Area of Science:
- Orthopedics
- Rheumatology
- Emergency Medicine
Background:
- Systemic lupus erythematosus (SLE) is rarely associated with patellar tendon rupture.
- Corticosteroid treatment for SLE may predispose patients to tendon pathologies.
Observation:
- An 18-year-old male with SLE presented to the emergency department with acute left knee pain and inability to extend the knee after a fall.
- Physical examination revealed a palpable defect in the patellar tendon and radiographs showed patella alta.
Findings:
- The patient was diagnosed with patellar tendon rupture.
- Surgical repair of the patellar tendon was successfully performed.
Implications:
- This case highlights the importance of considering patellar tendon rupture in SLE patients presenting with knee injuries.
- Prompt diagnosis and management in the emergency department are essential for favorable outcomes and preventing long-term disability.
- Further research is needed to understand the specific impact of SLE pathophysiology and corticosteroid treatment on patellar tendon integrity.

01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:26Nephrotic Syndrome II : Assessment and Medical Management
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...
