Table 8 Comparison of results with other studies
From: Results of total knee arthroplasty for painless, stiff knees
Knees | Mean follow-up period (years) | Mean ROM gain (preoperative to postoperative mean ROM change) | Mean functional score change | Rate and details of complications | |
|---|---|---|---|---|---|
Kim et al. (2017) [12] | 10 | 10.2 | 69 (9.5 to 78.5) | KSS; 42.6 to 68.6 FS; 39 to 66 | 30% (3 knees) Radiolucent lines around the tibial component (2) and skin edge necrosis (1) |
Bahn et al. (2006) [1] | 26 | 6.5 | 74 (0 to 74) | KSS; 47 to 75 | 24% (NA) Major complications (4 knees); fracture (1), hematoma needing reoperation (1), peroneal nerve palsy (1), and persistent stiffness (1) |
Naranja et al. (1996) [8] | 37 | 7.5 | 62 (0 to 62) | NA | 35% (16 knees) Patellar tendon or tibial tubercle avulsion (3), persistent pain requiring arthrodesis (1), joint stiffness requiring revision or arthrotomy for lysis of scar (2), aseptic loosening requiring revision (5), and deep infection (5) |
Our current study | 15 | 15.4 | 77.6 (0 to 77.6) | KSS; 36 to 76.9 FS; 50.9 to 67.2 | 33% (5 knees) Periprosthetic joint infection (2), Polyethylene-insert dislocation (1), severe extension lag after patella fracture (1), and aseptic loosening (1) |
