The basic science of continuous passive motion in promoting knee health: a systematic review of studies in a rabbit model

Knapik DM, et al. · Arthroscopy

In rabbits, CPM after cartilage injury improved cartilage nutrition and healing quality versus immobilization — the basic-science rationale (Salter's work) behind post-cartilage-repair CPM protocols. Animal support only; human benefit unproven.

Population

Rabbit-model studies of CPM after joint injury/surgery

Intervention

Continuous passive motion

Comparator

Immobilization or free activity

Limitations

Rabbit model; lesion sizes, joint loads and rehab durations do not map directly onto humans.
