Introduction

Early rehabilitation and discharge following minimally-invasive total hip arthroplasty has potential risks including the possibility that patients may become progressively anemic at home. The current study assess the use of pre-emptive autologous blood transfusion on the length of stay, readmission, and allogenous transfusion.

Methods

Patients treated by primary total hip arthroplasty using the superior capsulotomy technique were studied. Patients were divided into two groups. Group 1 were patients who did donate autologous blood and received an intra-operative pre-emptive transfusion. There were 283 patients in Group 1. Group 2 were patients who were medically capable of donating autologous blood but did not for non-medical reasons. There were 71 patients in Group 2. Patients who did not donate autologous blood for medical reasons (preoperative Hgb less than 11.5, age over 80) were excluded. All patients received general anesthesia. Length of stay, allogenous transfusion and readmission were compared.

Introduction

The current study reports on the impact of immediate mobilization of patients treated by tissue-preserving, computer-assisted total hip arthroplasty on length of stay, disposition, and complications.

Methods

From March, 2010 to April, 2011, a total of 231 consecutive primary THA were performed. Of these, 218 hips met the inclusion criteria of treatment using the superior capsulotomy surgical technique1 (Fig. 1), navigation of acetabular component implantation using a patient-specific mechanical navigation device (HipSextant™ navigation System, Surgical Planning Associates, Inc., Boston, MA)2, and patient age less than 80 years. Mean age of the patients was 57.3 years (range 23.5–79.9 years). The superior capsulotomy approach1 was used in all cases. This technique allows for both the femoral and the acetabular components to be placed with the patient in a lateral position through an incision in the superior capsule, posterior to the abductors and anterior to the short external rotators. The hip is not dislocated during surgery. Rather, the femur is prepared in situ through the top of the femoral neck, the neck is then transected, and the femoral head is excised en bloc. The acetabulum is prepared under direct vision using angled reamers, and the socket is placed with an offset inserter. The final construct is then reduced in situ. The protocol also involved the use of pre-emptive oral analgesia, pre-emptive autologous blood transfusion, and immediate mobilization3. Length of stay and disposition in this study group were compared to a cohort of 698 total hip arthroplasty performed at the same institution by all other techniques.
