Objective: Through comparing the hospitalization costs of total knee replacement (TKR) in People’s Hospital of Peking University in 2005 and 2010, to investigate the changing status of hospitalization costs on this operation and the impact of clinical pathway ( CP ) on controlling the hospitalization costs during 5 years , and provide references for controlling medical treatment cost reasonably. Methods: The patients are grouped into undergoing unilateral and bilateral TKR. The total hospitalization cost and cost of each category during 5 years are compared, and SAS 9.2 statistic software is applied to deal the data. Results: Compared with 2005, the total cost for TKR in 2010 decreased. All the charging items decreased, except implant material increased, especially the cost of surgery, hospital room, nursing and pharmacy. Specific to one knee replacement group and both knees replacement, the changing trend of cost is coincident with the total cost. Conclusion: The total cost for TKR in 2010 was lower than that of 2005, which might be the result of adopting CP since 2010. Nevertheless, the implant material cost accounted large proportion of hospitalization cost in 2010, and it has obvious increasing trend compared to 2005. This result is related the increasing application of the new edition of Artificial knee joint prosthesis. Controlling implant material cost is the effective method of decreasing medical costs for TKR.

Objective This study is aimed to compare sinus tarsi approach and conventional extensile L shape approach in the management of Sanders type III calcaneal fractures. Methods A total of 36 cases of Sanders type III calcaneal fractures treated in our hospital between August 2011 to February 2014(35 patients, 27males, 8 females. Nineteen of them were performed a limited open reduction and internal fixation(ORIF) via the sinus tarsi approach(as minimal invasive group), while the other 17 cas?es were performed ORIF via conventional lateral extensile L shape approach(as conventional group). X?ray films were taken post?operatively to record the changes of B?hler angle and Gissane angle. The AOFAS ankle hind?foot scale, visual analogue scale and the MOS item short from health survey(SF?36) were adopted to assess the therapeutic effect. Results The average follow?up peri?od of minimal invasive group was 14.6 months. And conventional group were followed up for average period of 18.3 months. All the fractures in the series had a boney union at or before the final follow?up. The immediate correction and final correction of B?hler angle and Gissane angle were significantly increased in both minimal invasive group and conventional group, while there was sig?nificant difference between the two groups. The median AOFAS score ,VAS score and SF?36 score of the minimal invasive group were 84.74±8.14,1.68±0.95 and 89.36±4.69, while those in the conventional group were 82.06±10.95,1.94±1.43and 86.71±5.39. There was no significant statistically difference between the two groups. No wound problem happened in the minimal invasive group, 3 cases of subtalar joint stiffness were found, and 1 developed traumatic arthritis. Respectively, 2 cases in conventional group got hematoma and dehiscence for each, 8 cases of subtalar joint stiffness were found, and 2 cases developed traumatic arthri?tis finally. Conclusion Limited ORIF via a sinus tarsi incision have the familiar therapeutic effects to ORIF via a conventional extensile L shape incision in the management of type III calcaneal fractures. But the former has the advantage of lower incision complication rate and lower stiffness subtalar joint rate.
