Failed Surgery

 

1.  Diagnosis incorrect

- other local (intra-articular eg meniscal tear)

- referred (hip or spinal pathology)

 

2.  Right diagnosis but wrong surgery

- osteotomy for advanced OA

 

3.  Right surgery performed inadequately

- poorly performed -  inadequate fixation for osteotomy

- incomplete - didn't address all pathology /  incomplete correction of deformity

 

4.  Recognized complication of well performed surgery

 

5.  Well performed surgery with inadequate rehabilitation

- patient motivation

- wrong rehab

- right rehab done poorly

 

6.  Progression of pathology or disease process

- progression of OA after osteotomy
