Ask a PT Response: "The lower level mat exercises for a hip ORIF and a total hip replacement (THA) are very similiar. The biggest difference is with exercise progression. Often times after an ORIF, the surgeon will require that the patient have either a non weight bearing status or a partial weight bearing status. This precaution will, therefore, not allow for the patient to perform exercises which require weight bearing ie. calf/heel raises in standing, partial wall slides, etc. On the other hand, patients who have undergone a THA will usually have a weight bearing as tolerated status which will allow for the patient to perform exercises in weight bearing. I hope this clears things up. Thanks for using CyberPT."
