The use of continuous passive motion following knee cartilage defect surgery: a systematic review

Fazalare JA, et al. · Orthopedics

Anecdotalcounts toward this tier

Despite near-universal use in cartilage-repair protocols, the human evidence could not support definitive conclusions about CPM benefit — only 4 heterogeneous low-level studies existed. CPM is tradition-and-theory driven, not proven.

Population
4 Level III human studies of CPM after knee cartilage restoration
Intervention
Continuous passive motion machines postoperatively
Comparator
No CPM / varied
Limitations
Only Level III evidence available; heterogeneity prevented pooling; no RCTs.
