Brief summary

Hamstring avulsion is a common misdiagnosis for FAI and there appears to be a relationship between these two diagnoses. This relationship has never been studied. This study could contribute significantly to the global understanding of this hard to treat entity.

Interventions

We will retrospectively review patients who suffered from hamstring problems and try and correlate these with FAI. We suspect these two entities are commonly being confused by mistake. The duration of the observation is approximately 6-12 months.

Patients whom their cartilage hip status was define as advanced OA, during surgery, or patients which, following surgery, would be instructed to avoid full weight bearing on the operated hip for more than 4 weeks j. Concomitant use of PRP or TA during the surgical procedure
