Peroneal Tendinitis: A case discussion of 17-years old Male Sprinter.

Peroneal Tendinitis: A case discussion of 17-years old Male Sprinter.

Background:

Peroneal tendonitis is an overuse injury characterized by inflammation of the peroneal tendons, specifically the peroneus longus and peroneus brevis. These tendons play a crucial role in stabilizing the ankle and foot during dynamic activities, such as running. Athletes with certain foot biomechanics, including high-arched feet or valgus alignment, are predisposed to this condition due to increased repetitive stress on these tendons.  

Case Summary:

Patient: 17-year-old male sprinter  

Complaint: Gradual onset of pain and mild swelling on the postero-lateral aspect of the right ankle.

Duration: 3-4 weeks  

Mechanism of Injury: Increased sprinting workload during training in preparation for an upcoming competition, combined with improper footwear.  

Clinical Presentation:

1. Pain localized to the posterolateral ankle, worsening with activity and improving with rest.  

2. Morning stiffness and discomfort during the first steps of the day.  

3. Difficulty performing lateral movements, leading to an impaired gait pattern.

Physical examination:

findings included:  

- A visible limp during walking/running.  

- Mild swelling and tenderness posterior to the lateral malleolus.

- Pain exacerbated on resisted foot eversion.  

- Sensory examination revealed slight irritation of the sural nerve, with reported burning on the lateral foot.  

Diagnostic Considerations  

Differential Diagnosis:

- Lateral ankle sprain  

- Chronic ankle instability  

- Sinus tarsi syndrome  

- Peroneal tendon subluxation or tear  

Imaging Studies:

-X-Ray: Ruled out bony abnormalities or fractures.

★★★MRI: could have been better for the confirmation(some article showed it as gold standard), but not done. ( Thickening of Peroneal tendons may confirmed Tenosynovitis)

Mechanism of Injury:

The process underlying the development of this condition is similar to a rope that has been repeatedly overloaded. In short, similar for a frayed rope. The patient’s condition is attributed to repetitive overload of the peroneal tendons during sprinting. Improper footwear and increased training intensity further exacerbated the mechanical stress.  

Treatment Plan:

Non-Operative Management:

The patient was advised to follow a structured treatment plan, which is supported by evidence from recent literature.  

1. Lifestyle/Activity Modification

   - Reduced sprinting and lateral movement activities for 4 weeks to allow inflammation to subside.  

   - Transitioned to controlled, low-impact activities such as cycling and swimming.  

2. Pharmacological Intervention

   - Prescribed NSAIDs (e.g., ibuprofen 400 mg TID) to reduce inflammation and pain (Hussain et al., 2023).  

3. Physical Therapy

   - Implemented a supervised rehabilitation program focusing on:  

     - Strengthening Exercises: Targeted exercises for peroneal muscle strengthening (e.g., resistance band eversion).  

     - Stretching: Focused on improving ankle flexibility to reduce stress on tendons.  

     - Proprioceptive Training: To enhance neuromuscular control of the ankle.  

4. Orthotics and Ankle Bracing 

   - Custom orthotics with recessed areas under the first metatarsal to correct foot biomechanics (Brent et al., 2022).  

   - Ankle bracing to limit excessive eversion and stabilize the joint.  

5. Cryotherapy

   - Applied ice packs for 15 minutes, 3–4 times daily to alleviate acute symptoms (Smith et al., 2021).  

6. Education

   - Counseling on proper footwear and the importance of progressive training loads.  

Follow-Up Plan:

- Reassess every two weeks to monitor progress.  

- Gradual return to running activities starting at week 6, incorporating sprint-specific drills by week 10.  

- Full recovery anticipated in 12–14 weeks with adherence to the protocol.  

Discussion  

Peroneal tendonitis represents a significant challenge for athletes, as it affects performance and poses a risk of chronic injury. Current evidence underscores the importance of conservative management, as surgical intervention is rarely required (Pomeroy & Amendola, 2023). Non-operative measures, such as strengthening, cryotherapy, and orthotics, have been proven to enhance recovery rates (Ryan et al., 2022).  

Addressing biomechanical risk factors is critical, as high-arched feet predispose athletes to excessive peroneal tendon loading (Davis et al., 2023). Early diagnosis and individualized treatment protocols can prevent progression to chronic tendonitis or tendon tears.
