| Objective:, by observing Unicompartmental knee Arhtroplasty (UKA) and Total Knee Arthroplasty (TKA) recently for the treatment of knee osteoarthritis clinical efficacy, to identify the the clinical curative effect of the single condyle and provide practical basis for the clinical promotion.Method:the patients were from nanjing university of Chinese medicine affiliated hospital in changzhou city in September 2013 ～ October 2014 orthopedics hospital patients. UKA11 cases, TKA12 cases. UKA male 1 case (1), female 10 cases (11). TKA male 3 cases (4) and female 9 cases (10 knees). To observe the surgical trauma index (blood loss, operating time points,90 ° of knee flexion, knee joint swelling degrees), make a comparison. Finally, two groups of patients before and after operation of VAS scores, knee flexion biggest degree, KSS, WOMAC score statistical analysis to compare the clinical curative effect of two groups of patients are 6 months follow-up time.Results:1.Trauma indicators:(1) the bleeding (total guide flow):the bleeding (180.0±30.332) of the UKA group ml obviously small all over the TKA group of ml (406.6±87.108). (2) the operating time:UKA due to just half a chamber between the displacement, which used time (37.73 ± 6.467) less than TKA clearly used time (67.08±6.895). (3) knee flexion 90° point: UKA used time was (5.45±0.473) days less than theTKA (8.42±2.065) days. (4) joint swelling degree diameter (knee weeks):1 week,2 weeks after theUKA (44.45±1.214,1.214±0.894) cm group were better than that of the TKA (46.00±1.706,1.706±0.996) cm, after 3 months, no statistical significance (P> 0.05).2. (1) UKA group 11 and 12 patients TKA has achieved satisfactory clinical efficacy. Postoperative incision is I/a healing, not present infection, lower limb deep vein thrombus, prosthesis loosening and other complications. (2) Of UKA group and TKA preoperative VAS, knee flexion biggest degree, KSS and WOMAC scores had no statistical significance (P> 0.05). Two groups of patients with preoperative there was no significant difference. (3) VAS score, VAS UKA group by preoperative (7.64 ±0.92) topostoperative follow-up time of(2.09 ±0.83) at the end of TKA group of VAS by preoperative(7.58±0.90).to postoperative follow-up time of (2.67±0.89)at the end of two groups of patients with pain relief, but at the time of the last follow-up,UKA is better than that of TKA group (P< 0.05). (4)Largest knee flexion,:at the time of the last follow-up UKA group (122.73±5.17)is obviously better than the TKA group (118.25±3.864) (P< 0.01).(5) KSS clinical, functional score:the last follow-up, two groups of patients with postoperative clinical and functional score, UKA group respectively (89.72± 1.42), (89.18±1.66), TKA group respectively (86.58±1.83), (84.91±1.62).6 WOMAC score: at the time of the last follow-up UKA group (6.18±0.98) than TKA group (7.91±1.08) (P< 0.01).Conclusion:UKA, TKA for unilateral compartment osteoarthritis were obtained satisfactory curative effect, UKA as little trauma, short operation time and quick recovery etc, as long as grasp indications, postoperative recent curative effect of UKA can be superior to TKA, worth clinical promotion. |
