Discoid lateral meniscus instability in children: part I. A new grading system of instability to clarify natural history

ConclusionA new presentation of DLM is presented: episodic locking phenomenon and blocked knee with flexion deficit. Clinicians should be wary of pseudo-improvement with the recovery of mobility after a period of the locked knee, which may be due to a progression towards the ultimate degree of instability. Clinical grading of instability has clarified the natural history of DLM-associated tearing.Level of evidenceIII.
