ABSTRACT
Objective To compare the early clinical efficacy of unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) for elderly patients with medial compartmental knee osteoarthritis.Methods A total of 35 elderly patients with medial compartmental knee osteoarthritis were selected from September 2014 to March 2018 in our hospital, of whom 16 cases treated by UKA were observation group and 19 cases treated by TKA were control group.ResultsThe operation time, intraoperative blood loss, the rate of perioperative blood transfusion, postoperative drainage volume and hospitalization stays of observation group were less than those of control group, the difference were significant (P＜0.05).Before the treatment, there was no significant differences in the KSS score between two groups (P＞0.05).After the treatment, KSS scores of two groups had been improved to some extent, and the observation group was better than the control group, the difference was significant (P＜0.05).No revision or infection happened in 1 year post-operative follow-up of either group.The observation group (0) were less than the control group (26.32％) in thrombosis rate, the difference was significantly (P＜0.05).ConclusionBoth UKA and TKA have certain early clinical efficacy, but UKA had advantages such as shorter operation time, shorter hospitalization, less pain, lower incidence of adverse reaction, which can promote the postoperative function recovery, the early clinical efficacy is more significant.
ABSTRACT
<p><b>OBJECTIVE</b>To compare clinical efficacy of double titanium plate and clavicular hook plate for the treatment of Neer II distal clavicular fracture.</p><p><b>METHODS</b>From April 2013 to June 2015, 42 patients with Neer II distal clavicle fractures were non-randomly selected, including 25 males and 17 females. All patients were fresh closed fractures. Twenty patients were treated with double titanium plate with tight rope(group A), including 11 males and 9 females aged from 16 to 49 years old with an average age of(33.8±10.7) years;the time from injury to operation ranged from 2 to 5 days with an average of (3.5±1.8) days. Twenty-two patients were treated with clavicle hook plate(group B), including 14 males and 8 females aged from 27 to 53 years old with an average age of (37.7±9.9) years;the time from injury to operation ranged from 2 to 5 days with an average of (3.1±2.0) days. Operative time, blood loss, hospital stays and postoperative complications were observed and compared; fracture healing were compared among preoperative, postoperative at 1, 3 and 6 months; VAS and ASES scoring were used to evaluate shoulder function.</p><p><b>RESULTS</b>All patients were followed up from 6 to 12 months with an average of 7.2 months. All incisions were healed at stage I. Blood loss in group A were less than that of group B(<0.05); while there were no significant difference in hospital stays and operative time between two groups. No shoulder pain occurred in group A, 4 cases occurred shoulder pain in group B, and had significant difference. Fracture healing time ranged from 3 to 6 months with an average of 4.3 months. VAS score and ASES score in group A were higher than that of group B in pain, function and total score.</p><p><b>CONCLUSIONS</b>Compared with clavicle hook plate, double titanium plate has advantages of shorter incision wound, less bleeding and simply operation, less complications, and could avoid pain for removing internal fixation. Over reduction of acromioclavicular joint during operation does not affect its superior curative effect. It is better choice for the treatment of Neer II distal clavicle fracture.</p>
