The Anterior drawer test is a hands-on knee exam used to check the stability of the anterior cruciate ligament (ACL). It looks for excessive forward movement of the shinbone (tibia) compared with the thighbone (femur). It is commonly used after sports injuries, falls, or twisting knee events. It is one part of a broader knee evaluation, not a standalone diagnosis.

The Lachman test is a hands-on knee exam used to assess the anterior cruciate ligament (ACL). It checks how much the shin bone (tibia) moves forward relative to the thigh bone (femur). It is commonly used in orthopedic clinics, sports medicine, emergency care, and physical therapy settings. It helps clinicians evaluate suspected ACL injury after a twist, pivot, or sports-related knee event.

CRPS after knee surgery refers to complex regional pain syndrome that develops in the leg following an operation on the knee. It is a pain condition where symptoms are often out of proportion to what is expected from typical surgical healing. The term is commonly used in orthopedics, sports medicine, pain medicine, and physical therapy when postoperative pain becomes unusually persistent and multifaceted. It helps clinicians communicate a specific pattern of pain plus nervous-system and tissue changes that may require specialized evaluation.

Complex regional pain syndrome is a chronic pain condition that can develop after an injury or medical procedure. It is defined by pain that is out of proportion to the original tissue injury and by changes in sensation, skin, and movement. It is commonly discussed in orthopedics, sports medicine, pain medicine, and rehabilitation settings. It can affect an arm or a leg, including the knee and lower limb after trauma or surgery.

Saphenous neuritis is irritation or inflammation of the saphenous nerve, a sensory nerve on the inner (medial) side of the knee and lower leg. It can cause burning, tingling, sensitivity to touch, or sharp pain along the medial knee, shin, or ankle area. It is commonly discussed in orthopedic, sports medicine, and pain settings when medial knee pain does not match typical joint findings. It may occur after injury, overuse, or surgery around the knee, but it can also appear without a clear trigger.

Peroneal neuropraxia is a temporary loss of peroneal nerve function due to a mild nerve injury. It can cause numbness, tingling, or weakness in the lower leg and foot, sometimes including “foot drop.” It commonly relates to compression or traction of the nerve near the outside of the knee (around the fibular head). Clinicians use the term to describe the *type and expected behavior* of the nerve injury, not a specific treatment.

Posterior tibial pulse is a palpable heartbeat felt in an artery on the inner side of the ankle. It reflects blood flow through the posterior tibial artery, a key vessel supplying the foot. Clinicians use it as part of a routine circulation check in the lower limb. It is commonly assessed in orthopedics, sports medicine, emergency care, and physical therapy settings.

Dorsalis pedis pulse is the pulse felt on the top of the foot. It reflects blood flow through the dorsalis pedis artery, a continuation of a lower-leg artery. Clinicians check it during routine exams and after injuries or surgery to screen circulation to the foot. It is commonly documented in orthopedic, sports medicine, vascular, and emergency care settings.

Ankle-brachial index is a simple test that compares blood pressure at the ankle to blood pressure at the arm. It is used to screen for reduced blood flow in the legs, most often from peripheral artery disease (PAD). Clinicians use it in vascular, primary care, sports medicine, and orthopedic settings when circulation may affect symptoms or healing. It helps separate blood-flow problems from joint, muscle, nerve, or tendon causes of leg pain.

Neurovascular examination knee is a structured check of nerve and blood vessel function around the knee and lower leg. It helps clinicians confirm that circulation and nerve signals to the foot and ankle are intact. It is commonly used after knee injuries, before and after procedures, and when swelling or pain could threaten tissues. It is also used in routine orthopedic and sports medicine assessments to document baseline status.
