Knee Flexionater to Avoid Motion Restoring Surgery

The goal of this clinical trial is to learn whether adding a stretching device to standard physical therapy can help people regain knee bending after total knee replacement surgery. Some people have difficulty bending their knee during recovery. When this happens, doctors may recommend another procedure called motion-restoring surgery to improve knee movement. This study aims to answer two main questions. First, does adding a hydraulic high-intensity stretching device to physical therapy help people regain knee bending after surgery? Second, does using the device affect recovery, daily activities, or the chance of needing another procedure? Researchers will compare two treatment approaches. One group will receive standard physical therapy alone. The other group will receive standard physical therapy and will also use a hydraulic high-intensity stretching device called the Ermi Knee Flexionater at home. Participants who receive the device will use it at home each day in addition to attending their physical therapy sessions. Researchers will measure how well participants can bend their knee and will ask questions about pain, daily function, and activity level. Participants will also complete simple walking and mobility tests. Study visits will occur about four weeks after surgery when participants enroll, and again at about eight weeks, twelve weeks, six months, one year, and two years after surgery. Researchers will compare results between the two groups to see whether the stretching device improves recovery after knee replacement.

Incidence and Determinants of Joint Contractures in Mechanically Ventilated ICU Patients

This prospective observational cohort study aims to evaluate the incidence and determinants of joint contracture development in mechanically ventilated adult patients admitted to the intensive care unit (ICU). Prolonged immobilization, deep sedation, and neuromuscular blockade are common in critically ill patients and may contribute to musculoskeletal complications, including joint contractures, which can adversely affect functional outcomes and rehabilitation after ICU discharge. Adult patients who are mechanically ventilated, immobilized, and have impaired consciousness will be consecutively enrolled and followed during their ICU stay. Joint range of motion will be assessed using standardized passive range of motion (PROM) measurements performed with a goniometer at predefined intervals by trained assessors. Joint contracture will be defined as a reduction of at least 33% in passive joint range of motion compared with normal reference values. This study is non-interventional, and all patients will receive routine ICU care and standard physiotherapy according to institutional protocols. No additional procedures or interventions will be applied for research purposes. Demographic characteristics, clinical variables, and ICU-related factors will be recorded to explore potential associations with contracture development. The findings of this study are expected to provide prospective data on the burden of joint contractures in mechanically ventilated ICU patients and to identify modifiable risk factors that may inform future preventive and rehabilitative strategies in critical care practice.
