RESUMO
BACKGROUND:Unicompartmental knee arthroplasty has been paid more and more attention because of its advantages of fewer traumas,less blood loss,less complications,faster recovery,excellent knee function and high prosthetic survival rate.Most of the relevant reports focused on its clinical effect,but the changes in the levels of relevant inflammatory cytokines in patients after unicompartmental knee arthroplasty were rarely reported. OBJECTIVE:To investigate the effect of unicompartmental knee arthroplasty in patients with medial compartment osteoarthritis of the knee and the changes of interleukin-1,interleukin-6,and tumor necrosis factor-α levels. METHODS:A total of 30 patients with medial compartment osteoarthritis of the knee who received unicompartmental knee arthroplasty from September 2021 to March 2023 and met the inclusion criteria were selected as the study subjects.Medial angle of proximal tibia,femoral and tibial angle,pain visual analog scale score,hospital for special surgery score,knee joint range of motion,synovial fluid interleukin-1,interleukin-6,and tumor necrosis factor-α levels before and after surgery were compared and statistically analyzed. RESULTS AND CONCLUSION:(1)All 30 patients had grade I wound healing.All patients were followed up for more than 6 months after surgery.There were no complications such as prosthesis loosening and dislocation of prosthesis liner in all patients.(2)The medial proximal tibia angle and the femoral and tibial angles measured after operation were significantly improved(P<0.05).(3)The visual analog scale score,hospital for special surgery score and range of motion measured at 1,3,and 6 months after operation were better than those before operation(P<0.05),and showed a gradual improvement(P<0.05).(4)The levels of interleukin-1,interleukin-6,and tumor necrosis factor-α in synovial fluid at 3 and 6 months after operation were decreased gradually compared with those before operation(P<0.05)and showed a gradual downward trend at each time point after operation.(5)It is indicated that unicompartmental knee arthroplasty can effectively treat medial compartment osteoarthritis of the knee,significantly relieve pain,restore knee joint function,improve knee varus deformity and lower limb strength line,and reduce the levels of inflammatory cytokines interleukin-1,interleukin-6,and tumor necrosis factor-α in joints to a certain extent.

RESUMO
Objective To investigate the curative effect of cocktail combined with tranexamic acid(TXA)on total knee arthroplasty(TKA)under the concept of enhanced recovery after surgery(ERAS).Methods Seventy patients with knee osteoarthritis who received unilateral TKA treatment admitted to the Second Affiliated Hospital of Bengbu Medical College from September 2020 to July 2022 were ret-rospectively analyzed.According to different treatment methods,they were divided into experimental group and control group,with 35 ca-ses in each group.Under the guidance of ERAS concept,the experimental group received injected intraarticular mixture of cocktail and TXA during the operation,while the control group received injected intraarticular mixture of cocktail and normal saline.Postoperative drainage volume,hemoglobin(Hb)decline and total blood loss at 3 days after operation,blood transfusion rate,first ambulation time,length of hospital stay,postoperative pain visual analogue scale(VAS)、knee range of motion(ROM)and HSS score at different time points after operation,delayed wound healing,wound infection and incidence of deep vein thrombosis were compared between the two groups.Results The postoperative drainage volume,decline of Hb and total blood loss at 3 days after operation,blood transfusion rate in the experimental group were less than those of the control group,the differences were statistically significant(P＜0.05).The first ambu-lation time and length of hospital stay in the experimental group were significantly lower than those of the control group,the difference were statistically significant(P＜0.05).There were no significant differences in pain VAS score at 1 day,2 days,3 days,7 days,14 days af-ter operation between two groups(P＞0.05).There were no significant differences in ROM at 7 days,14 days after operation and HSS score at 4 weeks,12 weeks after operation between two groups(P＞0.05).Conclusion Under the concept of ERAS,intraarticular in-jection of cocktail combined with TXA in TKA can effectively reduce postoperative blood loss,improve postoperative pain,reduce periop-erative risks,and promote better early postoperative rehabilitation,the clinical effect is significant.
RESUMO
BACKGROUND: Although there are many studies on acute patellar dislocation in adolescents, the optimal treatment strategy is under discussion.OBJECTIVE: To summarize the clinical efficacy of reconstruction of the medial patellofemoral ligament (MPFL) in the treatment of adolescent acute patellar dislocation using double-pulley technique.METHODS: Thirty cases of acute patellar dislocation were enrolled and received reconstruction of the MPFL using double-pulley technique. We proceeded to prepare the bone bed for anchor placement at the medial point of the superior edge of the patella and at the upper 1/3 patella along the long axis of the patella using arthroscopic grinding. Two double-loaded 5.0 anchors were respectively placed at the medial point of patella and at the upper 1/3 patella parallel to the patellar articular surface, and then tied using the double-pulley technique. Long longitudinal incisions were performed at the medial condyle and at the adductor tubercle to expose these two structures, the deep fascias tunnel between two incisions were penetrated to pull the tendon weave end through the tunnel until the lateral side along a femoral tunnel; finally the tendon was fixed using screws in appropriate tightness. All patients were followed for more than 10 months, and the patellar-related parameters and knee function parameters were compared before and after operation. RESULTS AND CONCLUSION: There were 12 cases of intra-articular cartilage injury and 4 cases of meniscus injury. The patella title angle, Q-angle and outward shift distance at the last follow-up were less than those before operation. Lysholm and International Knee Documentation Committee scores at the last follow-up were higher than those before operation. The mean operation time was (90±10.5) minutes. There was one patient with knee movement angle from 0° to 30° and one patient with a patellar fracture caused by slipping and treated with internal fixation. None of patients appeared with patellar dislocation, positive apprehension test infection or poor wound healing. These results indicate that the simple and mini-invasive double-pulley technique is a good treatment strategy for acute patellar dislocation, because it is consistent with patellar anatomical stability, holds patellar trajectory visibility, quick recovery and good curative effect. Additionally, osteotomy is recommended when the simple efficacy is not satisfactory.
RESUMO
BACKGROUND:Because of its advantages, Endobutton has been widely used in clinic. Currently, its shortcomings are increasingly recognized. Tightrope that overcomes the shortcomings of Endobutton has been gradualy accepted by a doctor skiled in sports injuries. OBJECTIVE: To analyze and compare the differences in the effects of Tightrope and Endobutton in the reconstruction of the cruciate ligament. METHODS:Totaly 60 cases of anterior cruciate ligament rupture were selected and subjected to anterior cruciate ligament reconstruction under arthroscopy, of which 30 cases were randomly assigned to reconstruction by Endobutton device and 30 cases underwent reconstruction by Tightrope device. Al operations were performed by the same surgeon. Al patients were subjected to regular functional exercise and were folowed up regularly after operation. Effects of Tightrope and Endobutton in the cruciate ligament reconstruction were evaluated by comparing various indexes in the two groups. RESULTS AND CONCLUSION:Compared to the Endobutton fixation system, the Tightrope fixation system could shorten the operation time, reduce the length of tendon incision, and decrease the loss of bone mass in the femoral bone tunnel. There were no significant differences in the maximum knee flexion, knee joint score and Tegner movement level score between the two groups at 3 and 6 months after operation. These findings indicate that the Tightrope fixation system is superior to the Endobutton fixation system, because it is more simple and convenient to operate and has less bone loss. However, their clinical efficacy has no difference after 6 months.
