Tibial Derotational Osteotomy for Patellofemoral Instability: A Systematic Review

Table 3

Mean anatomical correction of each procedure or combination of procedures in the included studies. These findings were confirmed by XR or CT.

Procedure (s) performed	Mean anatomical correction
TDO (n = 147) [19, 30, 32]	19.9 degrees (range, 5–45)
TDO + femoral derotational osteotomy (n = 11) [29, 31]	20.8 degrees (range, 5–45)
TDO + TTT (n = 12) [18]	34 degrees (range, 20–45)
TDO + TTT + TKA (n = 10) [17]	30 degrees (range, 20–35)

TDO = tibial derotational osteotomy; TTT = Tibial tuberosity transfer; TKA = total knee arthroplasty.
