Medial patellar ligament reconstruction in combination with derotational distal femoral osteotomy for treating recurrent patellar dislocation in the presence of increased femoral anteversion: a systematic review

Table 5 Complication, satisfaction rate, and radiological assessments^a

Lead Author	Complications	Satisfaction, %^b	Other Assessments
Zhang	MPFL residual graft laxity(n = 4)	Not reported	Residual J-sign, patellar medial laxity index
Hao	Limited knee flexion (n = 1)	96/4/0	Apprehension sign, J-sign, BPII score
Deng	none	Not reported	None
Zhang	Limited knee flexion (n = 3)	Not reported	J-sign, Patellar tilt
Nelitz	Limited knee flexion (n = 2)	92/8/0	None
Li	Osteotomy does not heal(n = 1)	Not reported	none

^aNo patients experienced patellar redislocation; however, 2.4% of patients after derotational femoral osteotomy showed medial patellofemoral ligament residual graft laxity
