Secondary Popliteal Fossa Cyst And Knee Osteoarthritis Related

Research purposesInvestigate the correlation of osteoarthritis of the knee secondary popliteal fossa cystResearch MethodsThe first part of the select normal bodies of15knee specimens, the structure of the anatomy of their knee, to observe the anatomical level, looking for knee structural anatomy of the weak points and secondary popliteal fossa cyst.The second part according to the epidemiological case-control study,200cases met the inclusion criteria of the study (case group with knee arthritis patients) and control group (non-osteoarthritis patients) of100cases), which secondary popliteal fossa cyst symptom score, symptom score of patients with knee osteoarthritis, the final judgment in the case group and control group of secondary popliteal fossa cyst constitute a significant difference between the availability and calculate the exposure odds ratio (OR), the relationship between the analysis of secondary popliteal fossa cyst symptom score and knee osteoarthritis, analysis of secondary popliteal fossa cyst incidence of knee osteoarthritis.The third section reviews the analysis of30cases of popliteal fossa cyst in patients with conservative treatment fails, the combined approach before and after arthroscopic treatment, were statistically analyzed to observe the knee internal structural changes and their relationship. Of30cases of secondary popliteal fossa cyst the Gubi mixture, and observed the therapeutic effect of the the Gubi mixture of clinical symptoms of secondary popliteal fossa cyst.ObservationsThe first part of the normal knee around the semimembranosus and medial head of gastrocnemius synoviae (gastrocnemius-semimembranosusbursa The GSB), internal and external flow of synovial fluid in the intra-articular pressure increases to the GSB. 1.115specimens were visible the GSB existence, is located between the semimembranosus attachment point and the medial tibial condyle and the deep surface of the medial head of gastrocnemius, the connective tissue fiber membrane covering the medial femoral condyle of the joint capsule surrounded by synovial fluid capsule. The cavity was slit-like, containing a small amount of synovial fluid.1.2GSB knee joint synovial capsule of the channel mouth or weak area, of which40%(6) specimens of the GSB and knee joint synovial capsule and condylar the same channel mouth was a horizontal crack-like structure, five specimens were the relevant section of the cavity lesions.60%(9) specimens GSB knee synovial capsule is not the same, but there are weak areas and condylar knee joint synovial capsule, nine specimens, three with intra-articular lesions.Internal and external flow of1.3of the knee joint cavity pressure increases synovial fluid to the GSBTake semi-curved knee, intra-articular injection of saline with blue ink, and intra-articular pressure is gradually increased, when the injection volume exceeds the maximum capacity of the knee joint cavity (88.0±5.6) ml, intra-articular fluid through the above channel mouth or weak regional inflow to the GSB or highlight. There is a significant correlation in the second part of secondary popliteal fossa cyst incidence and knee osteoarthritis2.1case and control groups, the secondary popliteal fossa cyst constitute a significant difference (P<0.005) between exposure odds ratio (OR)3.07, show that the secondary popliteal fossa cyst and knee osteoarthritis positive association; symptom scores in patients with secondary popliteal fossa cyst and increased with the increase in knee osteoarthritis score.The third part of the intra-articular disease, treatment can effectively improve the clinical symptoms of popliteal fossa cystReview of statistical analysis of30cases patients can be accompanied by joint disorders, of which nine cases of medial meniscus tear, lateral meniscus tear of seven cases, four cases of anterior cruciate ligament tear, osteoarthritis of10cases. Cyst openings are located inside of the popliteal fossa. Does not appear after the blood vessels, nerves, or complications of the surgical incision. In this group cases were followed up, time3-12months, an average of10month. Among them,1case of recurrence. The2cases patients appear the the popliteal fossa the Ministry of tenderness, but the the degree of compared with the preoperative Ming is now to improve the. Not more than27cases during follow-up of patients with knee pain sense.30patients in the postoperative B ultrasound or MRI follow-up cases of recurrence, more than29cases a good recovery. Patients classification:0and27cases of Class I, Division2cases of Class III patients.30patients before and after treatment VAS, popliteal fossa cyst score comparison, there were statistically significant. The Gubi mixture group of30patients taking8weeks, VAS score, popliteal fossa cyst scores before and after treatment was statistically significant.ConclusionA normal knee around there is the semimembranosus and medial head of gastrocnemius synoviae (gastrocnemius-semimembranosusbursa The GSB), structurally weak zone after knee synovial fluid in the intra-articular pressure increases to the GSB internal and external flows. Secondary popliteal fossa cyst incidence of knee osteoarthritis were significantly related to(3) knee joint related disease treatment can effectively improve the clinical symptoms of the popliteal fossa cyst...
