OBJECTIVE:
To analyze the evaluation and treatment of blood loss during total hip arthroplasty (THA) and total knee arthroplasty (TKA) in the aged .
METHODS:
We retrospectively surveyed the blood loss and the rehabilitation of 46 cases of TKA and 146 cases of THA older than 60.
RESULTS:
In the group younger than 70, the mean total blood loss of THA was 1425 mL and the hidden hemorrhage 729 mL (51%); following the TKA, the mean total loss was 1386 mL and the hidden hemorrhage was 890 mL (64%). In the group 70 and older, the mean total blood loss of THA was 1435 mL and the hidden hemorrhage was 769 mL (53%)û following the TKA, the mean total loss was 1380 mL and the hidden hemorrhage was 910 mL (65%). The difference of hidden hemorrhage between the THA and the TKA was both significant by different (p< 0.05). Age played an important part in the THA group (p< 0.05), but not in the TKA group (> 0.05).
CONCLUSION
The aged have poor resistance to blood loss. Hidden hemorrhage in the TKA or THA perhaps is the primary part of the blood loss. Prompt treatment is helpful for the rehabilitation.

BACKGROUND: Early stage osteonecrosis of the femoral head (ONFH) has many treatment options including core decompression with implantation of a tantalum rod. The purpose of this study was to evaluate clinical and radiological outcomes and potential complications during conversion total hip arthroplasty (THA) in such patients. METHODS: Six male patients (8 hips) underwent THA subsequent to removing a tantalum rod (group I) from April 2010 to November 2011. We retrospectively reviewed the medical records of these patients. We enrolled 12 age- and sex-matched patients (16 hips) during the same period, who had undergone primary THA without a previous operation as the control group (group II). All patients were followed for at least 3 years. We checked the Harris hip score (HHS), operative time, and volume of blood loss. Radiological results, including inclination, anteversion of the acetabular cup, presence of periprosthetic osteolysis, and subsidence of femoral stem were checked at the last follow-up. RESULTS: The mean preoperative HHS values were 56.5 (range, 50 to 62) and 59.1 (range, 42 to 70) in groups I and II, respectively. The HHS improved to 96.0 (range, 93 to 100) and 97.6 (range, 93 to 100), respectively, at the 3-year follow-up (p = 0.172). Mean operation time was 98.8 minutes (range, 70 to 120 minutes) in group I and 77.5 minutes (range, 60 to 115 minutes) in group II (p = 0.006). Total blood loss volumes were 1,193.8 mL (range, 960 to 1,360 mL) and 944.1 mL (range, 640 to 1,280 mL) in groups I and II, respectively (p = 0.004). No significant differences in inclination or anteversion of acetabular cup and no evidence of osteolysis or subsidence of the femoral stem were reported in either group in radiological follow-up results. However, one case of squeaking occurred in group I during the follow-up. CONCLUSIONS: The two groups showed no clinical or radiological differences except extended operative time and increased blood loss. However, the incidence of squeaking (1 of 8 hips) was higher, as compared to the control group or previously reported values.
