Non-weight bearing means keeping all body weight off an injured or treated limb when standing or walking. It is a common orthopedic instruction after certain fractures, surgeries, and serious soft-tissue injuries. Non-weight bearing is usually supported with assistive devices such as crutches, a walker, or a wheelchair. Clinicians use it to protect healing tissues and to reduce pain and mechanical stress.

PWB most commonly means **partial weight bearing**. It describes a **restricted amount of body weight** allowed through an injured or healing leg. PWB is commonly used after **knee surgery, fractures, or soft-tissue repairs**. It is also used during **rehabilitation and gait training** in physical therapy.

Partial weight bearing is a mobility restriction that limits how much body weight you place through an injured or healing leg. It is commonly used after knee surgery, fractures, or soft-tissue injuries to protect healing structures while keeping you moving. Clinicians usually pair it with crutches, a walker, or a cane to “share” load between the arms and the affected leg. The exact amount allowed varies by clinician and case.

TTWB stands for **toe-touch weight bearing**. It describes a **weight-bearing restriction** where the toes may touch the floor for balance, but the leg is not meant to support meaningful body weight. TTWB is commonly used after **knee, hip, ankle, or foot injuries and surgeries**. It is typically taught and monitored by orthopedic teams and physical therapists.

Toe-touch weight bearing is a walking restriction where the toes lightly touch the ground for balance, while most body weight stays off the leg. It is commonly prescribed after knee, hip, ankle, or foot injuries and surgeries. It is usually performed with crutches, a walker, or other support device. The exact amount of allowable loading varies by clinician and case.

WBAT stands for **Weight Bearing As Tolerated**. It means you may place as much weight through the leg as you can comfortably tolerate. WBAT is commonly written in orthopedic notes, hospital discharge instructions, and physical therapy plans after knee, hip, ankle, or foot problems.

Weight-bearing as tolerated is a common orthopedic instruction about how much body weight a person may place through an injured or operated leg. It generally means weight can be placed on the limb up to the level that feels tolerable, typically guided by pain and symptoms. It is widely used after knee injuries and many knee surgeries during rehabilitation. It is also used in physical therapy to support safe return to standing and walking.

Early mobilization means starting safe movement and activity soon after an injury, illness, or surgery. It is used to reduce the downsides of staying still for too long. In knee care, it often begins in the first days after a procedure or acute injury. It is common in orthopedics, sports medicine, physical therapy, and hospital-based rehabilitation.
