Outcome following mini-open lower limb fasciotomy for chronic exertional compartment syndrome

PurposeThe aim of this study was to report outcomes following mini-open lower limb fasciotomy (MLLF) in active adults with chronic exertional compartment syndrome (CECS). MethodsFrom 2013-2018, 38 consecutive patients (mean age 31 years [16-60], 71% [n=27/38] male) underwent MLLF. There were 21 unilateral procedures, 10 simultaneous bilateral and 7 staged bilateral. There were 22 anterior fasciotomies, five posterior and 11 four-compartment. Early complications were determined from medical records of 37/38 patients (97%) at a mean of four months (1-19). Patient-reported outcomes (including EuroQol scores [EQ-5D/EQ-VAS], return to sport and satisfaction) were obtained via postal survey from 27/38 respondents (71%) at a mean of 3.7 years (0.3-6.4). ResultsComplications occurred in 16% (n=6/37): superficial infection (11%, n=4/37), deep infection (3%, n=1/37) and wound dehiscence (3%, n=1/37). Eight per cent (n=3/37) required revision fasciotomy for recurrent leg pain. At longer-term follow-up, 30% (n=8/27) were asymptomatic and another 56% (n=15/27) reported improved symptoms. The mean pain score improved from 6.1 to 2.5 during normal activity and 9.1 to 4.7 during sport (both p<0.001). The mean EQ-5D was 0.781 (0.130-1) and EQ-VAS 77 (33-95). Of 25 patients playing sport preoperatively, 64% (n=16/25) returned, 75% (n=12/16) reporting improved exercise tolerance. Seventy-four per cent (n=20/27) were satisfied and 81% (n=22/27) would recommend the procedure. ConclusionMLLF is safe and effective for active adults with CECS. The revision rate is low, and although recurrent symptoms are common most achieve symptomatic improvement, with reduced activity-related leg pain and good health-related quality of life. The majority return to sport and are satisfied with their outcome.
