“…Patients with the pre operative flexion less than 75 degrees have shown an improvement and those with the pre operative flexion greater than 95 degrees a decrease in post operative flexion. 58,65 Shurman et al 66 . Who stated that one could anticipate gains in flexion for up to one year, with the most significant gains occurring within the first three postoperative months.…”

“…The functional range of knee motion has been studied extensively [7,30,40,49]. In general, gait and climbing slopes required greater than 90°knee flexion, using stairs and getting in and out of chairs required 90°to 120°fl exion, and getting in and out of a bath required 135°fl exion [40,50].…”

Although high-flexion TKA designs aim to safely accommodate deep flexion, it is unknown how often patients use deep flexion outside the laboratory. We used a validated smart-activity monitor to document the prevalence of knee flexion greater than 90°in 20 consecutive patients (21 knees) who had high-flexion TKAs, at a minimum of 2 years' followup. Patients wore the device continuously for a mean of 35.7 ± 0.5 hours. The 21 knees flexed more than 90°for an average of 10 ± 3.8 minutes (0.5%). Activities performed with flexion greater than 90°w ere, on average, 70% in single-limb stance, 12% moving from sitting to standing, 8% walking, 7% moving from standing to reclining, 2% stepping, 0.9% moving from lying to standing, and 0.1% running. Eight knees flexed greater than 120°for an average of 2.2 minutes (range, 0.2-15 minutes), or 0.1% of the testing time. Activities performed with flexion greater than 120°were, on average, 90% in single-limb stance, 6% moving from sitting to standing, 3% walking, 0.6% moving from standing to reclining, 0.3% stepping, and 0.1% moving from lying to standing. Peak flexion used at any time during testing was, on average, 84%

“…A range of 83-105 degrees flexion is required for normal daily activities and anything less severely affects a patient's quality of life [2][3][4][5]. This makes simple everyday tasks such as walking or climbing stairs difficult and tiring.…”

Range of motion (ROM) is an important outcome variable after total knee arthroplasty (TKA). This may be compounded by a pre-existing fixed flexion deformity (FFD). We therefore examined the long-term outcomes of patients with a flexion deformity undergoing TKA compared to those without a preoperative fixed flexion deformity. Participants who had undergone TKA at our centre between 1989 and 2002 were examined preoperatively, one, five and ten years after TKA (Kinemax PS; Howmedica, Rutherford, NJ, USA). Examining those with a preoperative FFD of greater than ten degrees with complete ten year follow-up data revealed 77 individuals. Seventy seven age, sex and body mass index matched patients were identified and the effect of TKA on indices of knee function (fixed flexion, maximum flexion, total ROM and Knee Society score (KSS) in both groups were analysed using repeated measures ANOVA. A significant difference between the groups with respect to fixed flexion (p<0.001), total ROM (p=0.001) and KSS (p<0.001) was observed between baseline and year one suggesting that those with a preoperative FFD improved more than those without. A significant difference with regard to fixed flexion was also observed between years one to five (p=0.001) and just failed to reach statistical significance between five to ten years (p=0.052) between the groups. This study demonstrates that patients with a preoperative fixed flexion deformity show continued improvement in their fixed flexion up to ten years post arthroplasty and have similar outcomes to those with no preoperative fixed flexion.
