Pes Anserine Bursitis Treatment & Management

Acute Phase
Rehabilitation Program
Physical Therapy
Patients with pes anserine bursitis need to work on both a hamstring stretching program and a concurrent closed-chain quadriceps strengthening program. This type of program can usually be taught to the patient by an athletic trainer or physical therapist. Patients should understand that, to gain the maximum benefit from this program, they need to stretch their hamstrings frequently during the day, sometimes hourly. The quadriceps strengthening program is recommended in most patients because of other concurrent pathology in the knee.
A regular program of hamstring stretching and quadriceps strengthening usually results in alleviation of the pain from pes anserine bursitis in approximately 6-8 weeks. Addition of a nonsteroidal anti-inflammatory drug (NSAID) may help to alleviate some of the pain at this time, and an ice massage may help to reduce inflammation. Cutting back or eliminating the offending activities is also important.
Recreational Therapy
In patients with generalized anterior knee pain, activity modification may be necessary to allow the joint to quiet down and to allow the hamstring tightness to resolve. In most patients, this modification involves minimizing the use of stairs, climbing, or other activities that cause irritation of the joint.
Surgical Intervention
The need for surgery is very rare in cases of pes anserine bursitis. Surgery is usually indicated in cases in which an immunocompromised patient has a localized infection that does not resolve with standard antibiotic treatment. Surgical decompression of the bursa may be indicated in such cases.
Consultations
Recalcitrant cases that do not respond to a program of activity modification and exercise may need a referral to a specialty-trained, sports medicine physician, primary care physician, or orthopedic surgeon for evaluation.
Other Treatment
Local anesthetic (typically lidocaine) and corticosteroid (Celestone) injection directly into the bursa is another treatment option. This should be considered only for refractory cases that have not responded to physical therapy, rest, ice, and nonsteroidal anti-inflammatory drugs (NSAIDs). No more than 3 injections should be used over a 1-year period, with at least 1 month between injections; however, patients who do not respond to the initial injection rarely respond to repeat treatments.[2] When injecting the bursa, make certain to avoid injecting any of the 3 tendons converging at the pes anserinus because this can intensify the patient’s pain and weaken the tendons.
Recovery Phase
Rehabilitation Program
Physical Therapy
During the rehabilitation program, the patient should incorporate the following measures:
- Continue with activity modification as necessary.
- Begin a gradual resumption of activities.
- Continue alternative training for cardiovascular fitness.
- After regaining full, pain-free motion with good isometric strength, work on improving strength and endurance.
Medical Issues/Complications
Pes anserine bursitis is primarily a self-limiting condition, which responds well to an exercise/stretching program.[9] Recalcitrant cases should be referred to a specialist to confirm the diagnosis and to rule out other causes of the patient's pain (eg, proximal tibial plateau fracture).
Surgical Intervention

Maintenance Phase
Rehabilitation Program
Physical Therapy
Continue to work on a hamstring stretching program and a concurrent closed-chain quadriceps strengthening program.
