Summary
Persistent knee joint instability, often following trauma, is a significant prearthrotic factor. This instability can lead to the development and progression of gonarthrosis (knee osteoarthritis) over time.
Area of Science:
- Orthopedics
- Rheumatology
- Sports Medicine
Background:
- Knee joint instability is often linked to gonarthrosis development.
- Understanding the progression of secondary gonarthrosis is crucial for patient outcomes.
Purpose of the Study:
- To investigate the relationship between prolonged knee joint instability and the development of secondary gonarthrosis.
- To identify factors influencing the onset and progression of gonarthrosis post-trauma.
Main Methods:
- Retrospective review of recent and primary radiograms from 32 patients with old knee trauma.
- Analysis of prolonged capsular and ligamentous instability.
- Correlation of instability duration with gonarthrosis development.
Main Results:
- All primarily intact knee joints developed gonarthrosis after an average of 46 months of instability.
- Pre-existing gonarthrosis generally worsened, with few exceptions.
- Arthrosis development tendency correlated with instability duration, not type.
Conclusions:
- Persisting knee joint instability, especially after combined capsular and ligamentous damage, is a significant prearthrotic factor.
- The duration of instability, rather than its type, influences gonarthrosis development.
- Previous surgical interventions did not appear to cause secondary gonarthrosis.
