Types of Knee Valgus
Knee valgus is categorized based on the severity of the inward bowing of the knees. Mild valgus may not cause significant symptoms, while moderate and severe cases can lead to substantial pain and dysfunction. The severity is typically assessed by physical examination and often quantified using goniometry or imaging techniques.
Anatomical Structures Contributing to Knee Valgus
| Structure | Potential Role in Valgus | Symptoms | Treatment Options |
|---|---|---|---|
| Femoral Morphology | Variations in the shape and angle of the femur (thigh bone) can predispose individuals to valgus. A shallow or inward-angled femoral condyle can increase the tendency for the knee to collapse inward. | Pain, instability, and potential for cartilage damage. | Strengthening exercises, bracing, and in severe cases, surgical intervention to correct the femoral alignment. |
| Tibial Morphology | A more inwardly angled tibia (shin bone) can contribute to the inward bowing of the knee. This can result in an increased Q-angle, further impacting knee alignment. | Pain, instability, and potential for joint degeneration. | Strengthening exercises, orthotics, and, in severe cases, surgical interventions to address the tibial alignment. |
| Patellofemoral Tracking | Malalignment of the patella (kneecap) within the femoral groove can contribute to valgus. This misalignment can cause increased friction and stress on the patellofemoral joint. | Pain, creaking, and potential for patellar tracking issues. | Strengthening exercises for the surrounding muscles, bracing, and, in severe cases, surgical interventions to correct the patellar alignment. |
| Muscle Imbalances | Weakness in the vastus medialis obliquus (VMO) muscle or tightness in the lateral structures can contribute to knee valgus. This imbalance creates an uneven force distribution across the knee joint. | Pain, instability, and potential for recurrent injuries. | Targeted strengthening exercises to improve muscle balance, stretching of tight muscles, and physical therapy. |
| Ligament Laxity | Increased laxity in the medial collateral ligament (MCL) can contribute to knee valgus. This ligament is responsible for providing stability to the knee joint. | Increased instability, pain, and potential for recurrent injuries. | Strengthening exercises to support the ligaments, bracing, and, in severe cases, surgical intervention to reconstruct or reinforce the MCL. |
Impact on Surrounding Joints
Knee valgus can have significant implications for the hip and ankle joints. Abnormal stress on the knee can lead to compensatory changes in the hip, potentially increasing the risk of hip pain and osteoarthritis. Likewise, altered foot mechanics and ankle alignment can also be affected by knee valgus. This can lead to problems such as plantar fasciitis and ankle instability.

Physical Examination Tests for Knee Valgus
A comprehensive physical examination is essential to evaluate the integrity and function of the knee joint. The following tests are commonly employed to assess for knee valgus:
| Test Name | Procedure | Expected Findings in Valgus | Interpretation |
|---|---|---|---|
| Valgus Stress Test | The examiner applies a valgus force to the knee while stabilizing the femur and tibia. | Excessive inward movement of the tibia relative to the femur, indicating ligament laxity. | Suggests possible medial collateral ligament injury or increased joint laxity. |
| Lachman Test | The examiner stabilizes the femur and grasps the proximal tibia. A pulling force is applied to assess anterior-posterior stability. | Excessive anterior translation of the tibia, indicating anterior cruciate ligament (ACL) injury. | This test evaluates anterior-posterior stability and is not directly related to valgus, but is often performed as part of a comprehensive knee evaluation. |
| McMurray’s Test | The examiner rotates the tibia internally and externally while flexing and extending the knee. | Clicking or popping sounds, or pain, especially on the medial aspect of the knee. | Suggests possible meniscal tears. This test can be helpful to evaluate the meniscus and rule out other internal derangements. |
| Anterior Drawer Test | The examiner stabilizes the femur and pulls the tibia forward. | Excessive forward movement of the tibia, indicating possible anterior cruciate ligament (ACL) injury. | Assesses anterior stability and is not directly related to valgus, but is often performed as part of a comprehensive knee evaluation. |
Patient Medical History
Gathering a comprehensive patient medical history is crucial for a thorough diagnosis. Key areas to explore include past injuries, surgeries, and any prior conditions that might be related to knee valgus. The patient should be questioned about the onset, location, and characteristics of the pain, as well as any associated symptoms like instability, clicking, or swelling. The duration of symptoms and any aggravating or relieving factors should be carefully documented.
This detailed history provides a context for understanding the patient’s condition and aids in developing an appropriate treatment plan. A detailed medical history, including details about the patient’s lifestyle and activity levels, is vital for a comprehensive assessment.
