Clinical Orthopaedics and Related Research
|August 1, 1986
Summary
Reflex sympathetic dystrophy (RSD) is an overlooked cause of unexplained knee pain. A study found 14 of 67 patients had RSD, supporting its diagnosis and guiding treatment.
Area of Science:
- Orthopedics
- Neurology
- Pain Management
Background:
- Knee pain of undetermined origin presents a diagnostic challenge.
- Reflex sympathetic dystrophy (RSD), now known as Complex Regional Pain Syndrome (CRPS), is rarely considered in knee pain cases.
Purpose of the Study:
- To evaluate the prevalence of reflex sympathetic dystrophy (RSD) in patients with unexplained knee pain.
- To characterize the clinical presentation and diagnostic findings of RSD in the knee.
- To establish treatment guidelines for RSD of the knee.
Main Methods:
- Retrospective chart review of 67 patients presenting with unexplained knee pain.
- Application of diagnostic criteria for reflex sympathetic dystrophy (RSD).
- Analysis of clinical profiles, physical examinations, and laboratory test results.
Main Results:
- 14 out of 67 patients (approximately 21%) met the diagnostic criteria for reflex sympathetic dystrophy (RSD).
- Specific clinical and physical findings were identified in patients diagnosed with RSD of the knee.
- Laboratory tests and treatment responses supported the diagnosis.
Conclusions:
- Reflex sympathetic dystrophy (RSD) should be considered in the differential diagnosis of unexplained knee pain.
- The study provides a basis for diagnosing and managing RSD affecting the knee.
- Further research may refine diagnostic and therapeutic approaches for this condition.
