Table 4

The literature review of joint-sparing limb salvage using JSE for reconstruction, showing complications and functional outcome.

Series	Year	No. of patients	Implant/allograft and site of the tumor	5 year survival of the implant or the allograft or last follow-up	Complications/revision	Infection	Recurrence	MSTS score
(1) Gupta et al. [4]	2006	8	Knee-sparing distal femoral endoprosthesis	Mean follow-up: 24 months	0	1 patient developed septicemia two weeks after surgery	0	The mean was 80% (57% to 96.7%)
(2) Agarwal et al. [3]	2010	6	Custom implant prosthesis	Mean follow-up: 12–27 months 1 patient died	0	2 deep infection	1	The score ranged from 27 to 30
(3) Wong et al. [6]	2013	8	6 femur, 1 tibia, and 1 proximal humerus	Mean follow-up: 41 months	0	0	0	The mean score was 29.1 (range, 28–30)
(4) Spiegelberg et al. [5]	2009	8	Stanmore proximal tibia replacement epiphyseal sparing	The mean follow-up: 35 months	1 periprosthetic fracture	0	1 converted to BKA	The mean score was 24 of 30 79% (57% to 90%)
