When to Start Physical Therapy After Shoulder Replacement

Shoulder replacement surgery involves replacing damaged parts of the shoulder joint with artificial components. This procedure aims to reduce pain and restore movement and function to a shoulder affected by conditions like arthritis or severe fractures. Physical therapy is essential for a successful recovery, helping to regain mobility and strength in the new joint.

Understanding the Initial PT Timeline

Physical therapy typically begins very soon after shoulder replacement surgery, sometimes even on the same day or within one to three days post-operation. This immediate start is important for preventing the joint from becoming stiff and promoting early healing. During these initial sessions, exercises are usually passive, meaning a therapist or a device moves the arm without the patient actively using their shoulder muscles. This approach helps protect the surgical repair while gently introducing motion.

Patients often receive instructions for specific exercises, such as gentle elbow and hand movements, even before leaving the hospital. These early exercises, like pendulum swings or grip strengthening, are important to prevent stiffness in the elbow, wrist, and hand, which can occur from immobilization in a sling. The goal is to maintain movement and circulation without putting stress on the healing shoulder.

Key Factors Influencing PT Initiation

The exact timing and intensity of physical therapy vary based on several factors unique to each patient and their surgery. The specific type of shoulder replacement performed—such as anatomic, reverse total, or hemiarthroplasty—significantly influences the rehabilitation protocol. For instance, anatomic replacement patients might start structured physical therapy within one to two weeks, focusing on passive range of motion. In contrast, reverse shoulder replacement patients may begin therapy around six weeks post-surgery, as their protocol emphasizes different muscle groups for movement.

The surgeon’s specific recommendations also play a large role in determining when physical therapy starts and how it progresses. A patient’s overall health, including any existing medical conditions, can influence the recovery timeline and the speed at which they can safely engage in therapy. The quality of the surgical repair and any findings during the operation, such as the condition of the rotator cuff, further guide the physical therapy plan.

The Focus of Early Rehabilitation

Following shoulder replacement surgery, the primary goals of physical therapy are to manage pain, reduce swelling, and protect the surgical site. Therapists often use techniques like ice application to help control discomfort and inflammation. Pain medication is also prescribed to help patients participate comfortably in early therapy sessions.

Early exercises focus on gentle range of motion, primarily passive or active-assisted movements where the therapist helps move the arm. This helps prevent the shoulder from stiffening without over-engaging healing tissues. Patients are usually advised to wear a sling for several weeks, often four to six, which helps immobilize and protect the shoulder joint. Precautions are in place to avoid movements that could jeopardize the repair, such as lifting anything heavier than a cup of coffee, pushing, pulling, or reaching behind the back.

Advancing Through Recovery: Long-Term PT

As healing progresses, physical therapy evolves from passive movements to more active participation. Around six to eight weeks after surgery, if healing is proceeding well, patients typically transition to active-assisted range of motion exercises, where they begin to use their own muscle power, often with assistance from a therapist or a device. This phase gradually progresses to active range of motion, allowing the patient to move the arm independently.

Strengthening exercises are typically introduced later in the rehabilitation process, often around 8 to 12 weeks post-surgery, to allow sufficient time for tissues to heal. This phase focuses on rebuilding muscle strength around the shoulder, improving stability, and enhancing endurance. Long-term goals of physical therapy include restoring full function, returning to daily activities, and improving overall shoulder strength and flexibility. Consistent adherence to the physical therapy program is important for achieving the best possible outcomes.
