The pes anserine bursa cushions the tendons that attach on the inner side of the shinbone, just below the knee. When it becomes irritated, it produces pain and tenderness in that spot, often mistaken for a problem inside the knee joint itself.
It is common in runners, in people with knee arthritis, and in those carrying extra weight. It is a benign, self-limiting problem that responds well to simple measures.
Symptoms
Typical complaints include:
- Pain and tenderness on the inner shin a few centimeters below the knee
- Pain with stairs, rising from a chair, or at night
- Sometimes mild swelling over the tender spot
How it is diagnosed
The diagnosis is clinical, based on tenderness localized to the pes anserine area rather than the joint line. Imaging is used mainly to rule out other inner-knee problems, such as a meniscus tear or arthritis, when the picture is unclear.
Pes anserine bursitis is treated without surgery. Dr. Lee starts with activity modification, addressing any underlying cause such as tight hamstrings, gait, or knee arthritis, along with anti-inflammatory measures and a stretching and strengthening program.
A corticosteroid injection into the bursa relieves stubborn cases. Because the bursitis is often a symptom of something else, like arthritis or a training error, treating that underlying factor is what keeps it from returning.
Non-surgical treatment
The condition responds to simple measures:
- Activity modification and addressing the underlying cause
- Stretching and strengthening, especially the hamstrings
- Anti-inflammatory measures and ice
- A corticosteroid injection for stubborn cases
Recovery timeline
Recovery is usually steady over a few weeks:
- Weeks 0 to 4Activity modification, stretching, and anti-inflammatory measures.
- Weeks 4 to 8Progressive strengthening and a graded return to activity, addressing the underlying cause.
What patients commonly misunderstand
Two things to recognize:
- It is not a problem inside the joint. The pain is from a surface bursa on the inner shin, not from inside the knee. Confirming that avoids unnecessary worry about a meniscus or cartilage problem.
- It often points to something else. Pes anserine bursitis frequently accompanies knee arthritis, tight hamstrings, or a training error. Treating that underlying factor is what prevents it from coming back.
