It is unclear whether combat casualties with complex hindfeet fractures would have an improved outcome with reconstruction or amputation. This study aimed to determine the outcomes of British military casualties sustaining calcaneal fractures. In the 12 years of conflict in Iraq and Afghanistan there were 116 calcaneal fractures in 98 patients. Seventy-four patients (74/98 76%) were contactable, providing follow up data for 85 fractures (85/116 73%). Median follow up was 5-years (64 months, IQR 52–79). Thirty limbs (30/85 35%) had undergone trans-tibial amputation at time of follow-up: there was no association between open fractures and requirement for amputation (p=0.06). Definitive treatment choice had a significant association with later requirement for amputation (p=0.0479). Fifty-two patients (52/74 70%) had been discharged from the military due to their injuries: there was a significant association between amputation and military discharge (p=0.001). Only 17 patients (17/74 23%) had been able to complete a military fitness test since their injury. The median physical component score of the SF-12 quality of life outcome tool for those undergoing amputation was 51.9 (IQR 48.1–54.3). The median for those retaining their limb was 44.1 (IQR 38.6–53.8). The difference between the two cohorts was not statistically significant (p=0.989).

This is a retrospective study examining the injury pattern, management and short-term outcomes of British Military casualties sustaining hindfoot fractures from the conflicts in Iraq and Afghanistan. In the 12-years of war, 114 patients sustained 134 hindfoot injuries. The calcaneus was fractured in 116 cases (87%): 54 (47%) were managed conservatively, with 30 (26%) undergoing internal fixation.

Eighteen-month follow-up was available for 92 patients (81%) and 114 hindfeet (85%). Nineteen patients (17%) required trans-tibial amputation in this time, with a further 17 (15%) requiring other revision surgery. Deep infection requiring surgical treatment occurred in 13 cases (11%) with S. aureus the commonest infective organism (46%). Deep infection was strongly associated with operative fracture management (p=0.0022). When controlling for multiple variables, the presence of deep infection was significantly associated with a requirement for amputation at 18 months (p=0.001). There was no association between open fractures and requirement for amputation at 18 months (p=0.926), nor was conservative management associated with amputation requirement (p=0.749).

Difficulties arise when counselling younger patients on the long-term sequelae of a minor knee chondral defect. This study assesses the natural history of patients with grade 2 Outerbridge chondral injuries of the medial femoral condyle at arthroscopy. We reviewed all arthroscopies performed by one surgeon over 12 years with Outerbridge grade 2 chondral defects. Patients aged 30 to 59 were included. Meniscal injuries found were treated with partial menisectomy. All patients had five-year follow up minimum. Primary outcome measure was further interventions of total or unicondylar arthroplasty or high tibial osteotomy. We analysed 3,344 arthroscopies. Average follow up was 10 years (Range 5–17 years). A total of 357 patients met inclusion criteria of which 86 had isolated medial femoral condyle disease. Average age was 50 at the time of arthroscopy. Average BMI at surgery was 31.7 and average chondral defect area was 450 mm². Isolated MFC chondral disease had a 10.5% intervention rate. Intervention occurred at a mean of 8.5 years post primary arthroscopy. In young patients Outerbridge II chondral injuries affecting ≥2 compartments have a high rate of further intervention within a decade. This information is crucial in counselling young patients on long-term sequelae of benign chondral lesions.
