The prevalence of knee pain has increased nearly 65% over the past two decades, leading to almost 4 million primary care visits annually. Understanding the mechanisms behind knee pain can empower individuals to seek timely assistance or treatment.
Common Causes of Knee Pain
Knee pain has a variety of causes, which can be broadly categorized into injuries and medical conditions. Some common reasons for knee pain include:
CauseDescriptionInjuriesRuptured ligaments, torn cartilage, and meniscus tears often result from sports or accidents, leading to sharp, stabbing pain.ArthritisConditions like osteoarthritis can lead to cartilage damage and inflammation in the joint, causing chronic pain.Mechanical ProblemsIssues with the alignment of the knee joint or inappropriate functioning of the joint components can contribute to discomfort.Patellofemoral Pain SyndromeThis syndrome results in sharp knee pain during activities such as climbing stairs or squatting, typically absent at rest [3].
Furthermore, over-the-counter medications like ibuprofen and naproxen sodium may provide relief, while topical treatments that contain numbing agents can also be beneficial [4].
Understanding these causes is vital for individuals experiencing stabbing pain in the knee cap to navigate their options effectively and seek appropriate treatment.
Sharp Knee Pain Causes
Understanding the root causes of sharp knee pain can aid in identifying effective treatment options. This section will explore common causes including soft tissue injuries, bone issues, and bursitis and inflammation.
Soft Tissue Injuries
Soft tissue injuries encompass various conditions that affect the ligaments, tendons, and muscles surrounding the knee joint. Examples include ligament sprains or strains, which can lead to sharp pain and instability in the knee. These injuries often arise from sudden movements or overexertion during sports. The damage to the knee cartilage lining or inflammation in the knee bursa can exacerbate this pain.

Potential Medical Conditions
Several medical conditions can contribute to stabbing pain in the knee cap. Understanding these conditions helps in identifying the appropriate treatment options.
Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an inflammatory autoimmune disorder primarily affecting the joints, including the knees. This condition can cause mild to intense throbbing and sharp pain, often accompanied by symptoms such as warmth, stiffness, or joint locking, particularly in cold weather or after waking in the morning. RA can lead to painful swelling in the knee joints, and if left untreated, it can result in bone erosion and joint deformity. Approximately 40% of people in Singapore are affected by this condition [3].
Symptoms of Rheumatoid ArthritisThrobbing knee painWarmth around the jointJoint stiffnessJoint locking
Treatment options for rheumatoid arthritis include non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, biological agents, and disease-modifying anti-rheumatic drugs (DMARDs).
Meniscus Tears
Meniscus tears are a common injury affecting the knee. The meniscus is cartilage that acts as a shock absorber between the thigh bone and shin bone. When tearing occurs, it can lead to sharp stabbing pain, particularly during twisting movements [3]. This injury is often associated with sports activities that require sudden stops, changes in direction, or any quick movements, making it prevalent in sports like basketball, soccer, tennis, and volleyball.

Osteoarthritis
Osteoarthritis is one of the leading causes of long-term knee pain, particularly in individuals over 65 years of age. This degenerative joint disease results from the wear and tear of cartilage, leading to restricted movement and increased pain, especially during weight-bearing activities.
Symptoms of OsteoarthritisChronic knee painSwellingStiffnessRestricted movement during activity
Movement can help alleviate stiffness associated with knee pain. Understanding these potential medical conditions assists individuals in recognizing the signs and symptoms of their knee pain, enabling timely and effective treatment.
