Abstract
ABSTRACTColonna capsular arthroplasty represents an option for the management of chronic hip dislocation in young patients with dysplasia. In the appropriate patient, modern capsular arthroplasty procedures may provide an opportunity for hip preservation in patients with preserved femoral head cartilage and not appropriate for total hip arthroplasty. Here, we review our experience with surgical dislocation of the hip and capsular arthroplasty in a 27-year-old female with congenital hip dysplasia and chronic superior hip dislocation. Due to inadequate native capsular tissue, a decellularized dermal allograft was used for interposition and capsular arthroplasty augmentation. The femoral head with preserved articular cartilage was reduced into the enlarged native acetabulum using a parachute technique to hold the allograft in position. Post-operatively, the patient was placed in a hip abduction brace and made non-weight bearing for six weeks. A conservative physical therapy protocol was implemented to allow gradual increase in weight bearing and range of motion over the first 12 weeks post-operatively.

Summary
Capsular arthroplasty has been performed for over 100 years as a treatment for complete hip dislocation in children and young adults. The technique involves wrapping the femoral head within the hip capsule prior to performing hip reduction into the true acetabulum. This technical note describes the use of a decellularized dermal allograft for interposition and capsular arthroplasty augmentation, due to inadequate native capsular tissue volume.
