Details and patient eligibility

About

This study will be conducted to investigate the effect of selected therapeutic exercises compared to standard exercise program in improving ROM, muscle strength and functional outcomes in distal femur osteosarcoma patients who have undergone tumor resection and modular knee endoprosthesis.

Full description

Osteosarcomas (OS) are the most common primary bone tumor and third most common cancer among children and adolescents after lymphomas and brain cancers (Wang et al., 2018; Luetke et al., 2014).

It is a primary malignant bone tumor with a worldwide incidence of 3.4 per million people per year (Mirabello et al., 2009). They are characterized by the production of osteoid, or immature bone, by malignant mesenchymal cells (Wang et al., 2018; (Luetke et al., 2014).

Patients displayed some persisting physical difficulties including incapability to perform active range of motion (ROM), decreased muscle strength, altered gait and sit-to-stand patterns, yet they maintained high levels of emotional acceptance and coping. A surprising but important finding was the persisting hip weakness in both operated and non-operated limbs, which extends up to 42 months after resection around the knee. This indicates that continued rehabilitation programs emphasizing hip strengthening should be considered for these patients, even years after surgery (Beebe et al., 2009). Furthermore, ROM exercises, strengthening exercises and balance exercises improve overall Quality of life (QOL) for these patients (Marchese et al., 2006).

40 participants in 2 patient groups

Standard Rehabilitation Group

Experimental group

Description:

Standard Rehabilitation Group: will receive the standard protocol of king Hussein hospital 6 weeks post-operative which is: Start aggressive knee flexion exercises and increase the extensor strength. Consider CPM/dynasplint if flexion \<60_ MUA contraindicated. Examination under anesthesia can be done to assess the cause of limited knee flexion. Surgical release is indicated if knee flexion is \< 60 degrees at six months after surgery.

Treatment:

Other: standard rehabilitation protocol

Supervised Rehabilitation Group

Experimental group

Description:

Supervised Rehabilitation Group: will receive supervised rehabilitation program 1 session / week for 45 minutes-1 hour.

Treatment:

Other: standard rehabilitation protocol
