Effectiveness of inpatient versus outpatient rehabilitation following total knee arthroplasty on clinical and functional outcomes in Germany: a non-randomized clinical trial

Abstract Background Rehabilitation models following total knee arthroplasty (TKA) vary internationally. The German healthcare system typically involves an initial hospital stay of 8–10 days, followed by a 3-week intensive rehabilitation program, which is delivered in either an inpatient or outpatient setting.
