Primary | Successful Pain Reduction After 12 Months (= 2 Points on a Numeric Rating Scale) | The primary end point is the relevant reduction of the average pain of the last four weeks in the legs (= 2 points on a Numeric Rating Scale; German Pain Questionnaire) 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation. | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Change in Pain Severity as Assessed by German Pain Questionnaire | Change in severity according to von Korff et al. (1992) regarding pain in the legs (stage I, II or III). The severity is calculated based on the questions of the German Pain Questionnaire according to von Korff et al (1992). The assessment of the pain intensity as well as the impairment and information on the days of impairment are included in the calculation of the severity (classes 0 = no pain to 4 = high, pain-related impairment, strongly limiting). | 12 months after completed liposuction treatment (intervention group) or after randomization (control group) compared with the time of randomisation) | |
Secondary | Change in Health-Related Quality of Life According to SF-36 Questionnaire | Change in health-related quality of life according to SF-36 questionnaire. | 12 months after completed liposuction treatment (intervention group) or after randomization (control group) compared with the time of randomisation) | |
Secondary | Change in Health-Related Quality of Life According to DLQI Questionnaire | Change in health-related quality of life according to DLQI questionnaire (a clinically relevant change corresponds to = 4 points change in DLQI sum score). | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Change in Health-Related Quality of Life According to WHOQOL-BREF Questionnaire | Change in health-related quality of life according to WHOQOL-BREF questionnaire. | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Change in Total Impairment According to Schmeller et al. (2010) | Total impairment is measured by taking the mean of 7 numerical rating scales assessing the domains pain (spontaneous, pressure), swelling, hematoma, movement, cosmetic appearance and quality of life (0 (none) - 10 (always/very strong) points), see Schmeller et al. (2010). | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Altered Depression Tendency According to PHQ-9 Questionnaire | Altered depression tendency according to PHQ-9 questionnaire (a clinically relevant improvement corresponds to = 5 points reduction in PHQ-9 sum score). | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Altered Hematoma Tendency According to Schmeller et al. (2010) | Hematoma ("Are you prone to bruising?") is measured by a numerical rating scale (0 (none) - 10 (always/very strong) points), see Schmeller et al. (2010). | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Changed Prevalence of Edema | Changed prevalence of edema | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Change in the Scope of the Physical Therapy | The scope of the physical therapy is measured by the number of treatment sessions per month. | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Change in Body Fat Percentage According to Wright et al. (1981) | Change in body fat percentage, determined according to formula from Wright et al. (1981), collected by means of measuring tape at the following points:
abdominal circumference: measurement at the level of the navel. The tape measure is placed horizontally around the body neck circumference: measurement below the larynx body size hip circumference: the widest part of the hip is measured. |
12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Change of Leg Circumference by Means of Measuring Tape | Change of leg circumference of the left and right leg by means of measuring tape at five specified measuring points:
lower leg cuffs calf center knee 10 cm below the groin hips (iliac crest). |
12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Movement Restriction Reduction According to LEFS Sum Score | Relevant reduction in movement restriction (stage I, II, or III; = 9 points improvement in LEFS sum score) | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Number of Recurrent Interventions | Number of recurrent interventions | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Number of (Serious) Adverse Events | Number of (serious) adverse events | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Number of Therapy Interruptions Caused by Adverse Events | Discontinuation of therapy caused by adverse events | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) | |
Secondary | Optional: Change of the Leg Volume by Means of Perometry | Optional: Change of the leg volume of the left and right leg (e.g. by means of perometry etc.) | 12 months after completed liposuction treatment (intervention group) or after randomisation (control group) compared with the time of randomisation) |
