OBJECTIVETo study the pharmacological properties of Tougu Xiaotong Granule (TGXTG) in preventing and treating knee osteoarthritis (KOA) at the molecular level.
METHODSThe computational methods, including principal component analysis, molecular docking, target-ligand space distribution, and the predictions of absorption, distribution, metabolism, excretion and toxicity (ADMET), were introduced to characterize the molecules in TGXTG.
RESULTSThe structural properties of molecules in TGXTG were more: diverse than those of the drug/drug-like molecules, and TGXTG could interact with significant target enzymes related to KOA. In addition, the cluster of effective components was preliminarily identified by the target-ligand space distributions. As to the results of ADMET properties, some of them were unsatisfactory, and were merely regarded as references here.
CONCLUSIONBased on this computational pharmacology study, TGXTG is a broad-spectrum recipe inhibiting many important target enzymes, which could effectively postpone the degeneration of spectrum cartilage by coordinately inhibiting the biological effects of cytokines, matrix metallopeptidase 3, and oxygen free radicals. radicals.

OBJECTIVES:
To evaluate the efficacy of different ways of cocktail analgesic mixture injection on total knee arthroplasty (TKA).
METHODS:
A total of 50 patients with knee osteoarthritis treated by TKA from July to September 2018 were randomly divided into two groups (=25). The Group 1 underwent anterior intra-articular injection before prosthesis implanted while the Group 2 underwent posterior intra-articular injection before prosthesis implanted. Visual Analogue Scale (VAS) of all patients for pain during activity and at rest, maximal flexion degree of the knee at the 48th h and the 72th h after surgery, the time of raise leg, usage rate of patient-controlled analgesia (PCA), and complications were evaluated and analyzed.
RESULTS:
VAS for pain at rest of patients in the Group 1 was significantly less than that in the Group 2 at the 6th, 12th, and 24th h after surgery (all <0.05). Maximal flexion degree of the knee at the 48th h and the 72th h after surgery in the Group 1 was better than that in the Group 2 (both <0.05). The Group 1 costed less time than the Group 2 on the ability to perform an active straight leg raise (=0.027).
CONCLUSIONS
The anterior intra-articular cocktail analgesic mixture injection can strongly relieve the pain early after TKA, which can improve knee function and achieve painless rehabilitation in most patients, with safety.

OBJECTIVE:
To investigate the effectiveness of preemptive analgesia with imrecoxib on analgesia after anterior cruciate ligament (ACL) reconstruction.
METHODS:
A total of 160 patients with ACL injuries who met the selection criteria and were admitted between November 2020 and August 2021 were selected and divided into 4 groups according to the random number table method (n=40). Group A began to take imrecoxib 3 days before operation (100 mg/time, 2 times/day); group B began to take imrecoxib 1 day before operation (100 mg/time, 2 times/day); group C took 200 mg of imrecoxib 2 hours before operation (5 mL of water); and group D did not take any analgesic drugs before operation. There was no significant difference in gender, age, body mass index, constituent ratio of meniscal injuries with preoperative MRI grade 3, constituent ratio of cartilage injury Outerbridge grade 3, and visual analogue scale (VAS) score at the time of injury and at rest among 4 groups (P>0.05). The operation time, hospitalization stay, constituent ratio of perioperative American Society of Anesthesiologists (ASA) grade 1, postoperative opioid dosage, and complications were recorded. The VAS scores were used to evaluate the degree of knee joint pain, including resting VAS scores before operation and at 6, 24, 48 hours, and 1, 3, 6, and 12 months after operation, and walking, knee flexion, and night VAS scores at 1, 3, 6, and 12 months after operation. The knee injury and osteoarthritis score (KOOS) was used to evaluate postoperative quality of life and knee-related symptoms of patients, mainly including pain, symptoms, daily activities, sports and entertainment functions, knee-related quality of life (QOL); and the Lysholm score was used to evaluate knee joint function.
RESULTS:
All patients were followed up 1 year. There was no significant difference in operation time, hospitalization time, or constituent ratio of perioperative ASA grade 1 among 4 groups (P>0.05); the dosage of opioids in groups A-C was significantly less than that in group D (P<0.05). Except for 1 case of postoperative fever in group B, no complications such as joint infection, deep vein thrombosis of the lower extremities, or knee joint instability occurred in each group. The resting VAS scores of groups A-C at 6 and 24 hours after operation were lower than those of group D, and the score of group A at 6 hours after operation was lower than those of group C, and the differences were significant (P<0.05). At 1 month after operation, the knee flexion VAS scores of groups A-C were lower than those of group D, the walking VAS scores of groups A and B were lower than those of groups C and D, the differences were significant (P<0.05). At 1 month after operation, the KOOS pain scores in groups A-C were higher than those in group D, there was significant difference between groups A, B and group D (P<0.05); the KOOS QOL scores in groups A-C were higher than that in group D, all showing significant differences (P<0.05), but there was no significant difference between groups A-C (P>0.05). There was no significant difference in VAS scores and KOOS scores between the groups at other time points (P>0.05). And there was no significant difference in Lysholm scores between the groups at 1, 3, 6, and 12 months after operation (P>0.05).
CONCLUSION
Compared with the traditional analgesic scheme, applying the concept of preemptive analgesia with imrecoxib to manage the perioperative pain of ACL reconstruction can effectively reduce the early postoperative pain, reduce the dosage of opioids, and promote the early recovery of limb function.

BACKGROUND: The authors report the results of preserving the infrapatellar branch of the saphenous nerve during unicompartmental knee arthroplasty to prevent lateral skin numbness. METHODS: All 100 cases had medial compartmental osteoarthritis and a minimally invasive technique had been used. The mean follow-up duration was two years and eight months (range, 24 to 42 months). RESULTS: The classification according to the location of this nerve was observed as either Mochida Type I with 76 cases (76%), Type II with 16 cases (16%), and unclassified type with 8 cases (8%). In Type I, the nerve was saved in 62 cases (82%), but could not be preserved in Type II because of the surgical procedure. These results showed that the mean distance from the joint line to the nerve of Type I was 9.13 mm (range, 4 to 15 mm) and the nerve passed inferiorly. CONCLUSIONS: This study showed the location of this nerve can be predicted ahead of the procedure, which will help preserve it during the surgery.

Journal of Korean Academy of Nursing 2008;38(1):11-18
PURPOSE: This study was to determine whether the Sun-style 24 forms of Tai Chi exercise improve pain, stiffness, disability, knee joint motion, mobility, balance or falling. METHOD: Forty-six community-dwelling elderly subjects (mean age, 75.46+/-6.28) voluntarily participated in an intervention group of either 24 forms of Sun-style Tai Chi for 60 min, 2 times per week for 12 weeks or a control group. A non-equivalent pretest-posttest design was used. Independent t-test and ANCOVA were used to examine group differences by using SPSS12.0. RESULT: The experimental group had significantly less pain (F=7.60, p=.008) and stiffness (t=-3.19, p=.003) than the control group. Also there were significant improvements in knee joint motion on the right knee (t=2.44, p=.019), left knee (t=2.30, p=.026), rising time (F=8.03, p=.07), balance on the left single leg test (t=2.20, p=.033), and fear of falling (t=-2.33, p=.024) in the Tai Chi exercise group. No significant group differences were found in disability and falls efficacy. CONCLUSION: The Sun-style 24 forms Tai Chi exercise is effective in decreasing pain, stiffness, fear of falling and it improves balance, rising time, and knee joint motion. We suggest a continuing long term intervention to decrease disability and increase efficacy concerning falls.

7.Influencing Factors for Fear of Falling in Degenerative Arthritis Patients.
Journal of Korean Academy of Nursing 2007;37(7):1184-1192
PURPOSE: The purpose of this study was to examine the relationship among fear of falling, pain, anxiety and depression, and to identify influencing factors in elderly women patients with degenerative arthritis living in the community. METHOD: The subjects of this study were 297 elderly women patients with degenerative arthritis. Data was collected by personal interviews using questionnaires. Data was analyzed by the SPSS(version 12.0) computer program, and it included descriptive statistics, one-way ANOVA, Pearson correlation coefficient, and Stepwise multiple regression. RESULTS: There was a significant difference (p= .000) in fear of falling according to the level of pain, anxiety, and depression. There was a significant positive correlation among fear of falling, pain, anxiety and depression. Depression, pain, number of medication, age, and anxiety showed significant predictors (43.5%) for fear of falling. CONCLUSION: This study suggested that thoroughly assessing predictors making an impact on fear of falling in the initial nursing assessment is the most important for falls prevention of elderly women patients with degenerative arthritis in the community.

BACKGROUNDResearchers initially proposed the substitution of apoptotic chondrocytes in the superficial cartilage by injecting mesenchymal stem cells (MSCs) intraarticularly. This effect was termed as bio-resurfacing. Little evidence supporting the treatment of osteoarthritis (OA) by the delivery of a MSC suspension exists. The aim of this study was to investigate the effects of injecting allogenic MSCs intraarticularly in a rat OA model and to evaluate the influence of immobility on the effects of this treatment.
METHODSWe established a rat knee OA model after 4 and 6 weeks and cultured primary bone marrow MSCs. A MSC suspension was injected into the articular space once per week for 3 weeks. A subgroup of knee joints was immobilized for 3 days after each injection, while the remaining joints were nonimmobilized. We used toluidine blue staining, Mankin scores, and TdT-mediated dUTP-biotin nick end labeling staining to evaluate the therapeutic effect of the injections. Comparisons between the therapy side and the control side of the knee joint were made using paired t-test, and comparisons between the immobilized and nonimmobilized subgroups were made using the unpaired t-test. A P value < 0.05 was considered significant.
RESULTSThe three investigative approaches revealed less degeneration on the therapy sides of the knee joints than the control sides in both the 4- and 6-week groups (P < 0.05), regardless of immobilization. No significant differences were observed between the immobilized and nonimmobilized subgroups (P > 0.05).
CONCLUSIONSTherapy involving the intraarticular injection of allogenic MSCs promoted cartilage repair in a rat arthritis model, and 3-day immobility after injection had little effect on this therapy.

OBJECTIVETo study therapeutic effects of embracing knee and rolling lumbar (EKRL) training on the pain and the function of lumbar of patients with degenerative osteoarthritis of lumbar spine.
METHODSFrom 2006.8 to 2008.1, 150 patients with degenerative osteoarthritis of lumbar spine were randomly divided into the control group, EKRL training group and the combined group. In the control group (n=50), there were 16 females and 34 males, the average age was (58.8 +/- 10.2) years and the average course of diseases was (16.3 +/- 14.9) months. In the EKRL training group (n=50), there were 13 females and 37 males, the average age was (60.1 +/- 8.2) years and the average course of disease was (17.1 +/- 15.3) months. In the combined group (n=50), there were 15 females and 35 males, the average ages was (59.9 +/- 11.4) years and the average course of diseases was (19.8 +/- 17.2) months. The patients in three groups were treated with Meloxicam tablets, EKRL training and two above methods combination respectively. After 3 weeks treatment, the curative effect, the visual analogous scores and the ODI indexes were observed. All the patients were followed up and the duration ranged from 6 to 24 months; the changes of average ODI indexes were observed monthly.
RESULTSAfter 3 weeks treatment, the therapeutic effects in three groups had obvious difference after Ridit analyses: there were significant differences between the combined group and other two groups (P<0.01), but no obvious differences existed in other two groups. Compared with before treatment, the visual analogue scale scores and the ODI indexes in three groups reduced significantly (P<0.01). After treatment, the visual analogue scale scores and the ODI indexes of the combined group had significant differences compared with those of other two groups (P<0.01), but the ODI indexes of other two groups had no obvious differences. After 6 to 24 months following-up, the monthly changes of average ODI indexes of EKRL training and combined groups had obvious differences compared with that of the control group (P<0.01).
CONCLUSIONEKRL training is a simple, no expense and effective methods for preventing and treating degenerative osteoarthritis of lumbar spine.

OBJECTIVETo improve the effect of operative management of acetabular fractures.
METHODSOne hundred and seventy eight acetabular fractures were treated operatively from August 1993 to December 2000. Their functional results and complications were analyzed.
RESULTSOne hundred and twelve hips were followed up for an average of 45.7 months. Heterotopic ossification was noted in 26 hips, post-operative osteoarthritis in 22 hips, avascular necrosis of the femoral head in 8 hips, and sciatic nerve injury in 7 hips after operations. No death and infection were found in this series.
CONCLUSIONSEctopic bone formation develops at extended ilio-femoral and Kocher-Langeneck approaches. Cartilaginous injury of the femoral head is contributable to post-operative osteoarthritis, and imperfect reduction is an important factor in the genesis of osteoarthritis.
