Outcome of single-stage total hip arthroplasty in advanced active tubercular arthritis of the hip in Indian patients

Table 5 Comparison of our study with other similar studies in terms of type of arthroplasty, stage of surgery and revision surgery

Ref.	Follow up period	Type of arthroplasty	Single vs two stages	Revision surgery	Limitation of study	Direction for future research
Our study	18 months	Cemented/uncemented/hybrid	Single stage	0	Relatively short period of follow-up	Long follow-up is required to comment upon implant longevity
Yoon et al[15]	4.8 years	Cementless	Single stage	0	Retrospective analysis of seven patients	Prospective study with a greater number of patients is desirable
Wang et al[35]	49 months	Cementless/cemented	Single stage	0
Bhosale et al[33]	10.5 years	Cemented/cementless/hybrid	-	7 aseptic loosening	Although patients were evaluated in two phases, there is no patient with an active sinus	A comparative study with and without an active sinus will clarify the impact of sinus on disease recurrence
Zhang et al[44]	41.6 months	-	1/2/3 stage	0	Type of arthroplasty not mentioned	Type of THA (cemented vs cementless) should be clearly mentioned

THA: Total hip arthroplasty.
