Summary
Even with normal arthroscopic findings, knee complaints can persist or worsen. Quadriceps muscle wasting was common in symptomatic patients, highlighting the importance of exercise for knee health.
Area of Science:
- Orthopedics
- Sports Medicine
- Rehabilitation
Background:
- Knee complaints are common, but arthroscopic findings are not always indicative of the underlying pathology.
- Understanding long-term outcomes for patients with knee pain and normal arthroscopy is crucial for effective management.
Purpose of the Study:
- To evaluate the clinical outcomes of patients with knee complaints and normal arthroscopic findings.
- To identify factors associated with symptom persistence or worsening in this patient group.
Main Methods:
- Prospective clinical follow-up of 96 patients with knee complaints and normal arthroscopic findings.
- Mean observation time of 10 months.
- Clinical re-examination to assess symptoms and identify potential causes for worsening.
Main Results:
- One-third of patients remained asymptomatic, one-third improved, and one-third had unchanged or worsened symptoms.
- Soft tissue alterations around the knee were implicated in symptom worsening for some.
- A subset of patients experienced worsening knee symptoms alongside complaints in other body regions, suggesting a potential psychosomatic factor.
- Quadriceps muscle wasting was prevalent in patients with persistent symptoms.
Conclusions:
- Knee complaints with normal arthroscopic findings can have varied outcomes.
- Quadriceps muscle atrophy is a significant finding in patients with ongoing knee symptoms.
- Energetic exercise programs are recommended for knee health, even in the absence of arthroscopic abnormalities.
