The majority of the cups demonstrated early radiographic instability, and this was not related to incomplete seating. Five year functional outcome appears good and independent of migration and initial seating.

This study suggests that obese class III TKA patients are at increased odds of superficial and deep SSI compared to other BMI cohorts. Interestingly, male obese class III patients demonstrated a higher rate of deep infection compared to their female counterparts. However, it must be noted that study findings are limited as confounders were unable to be accounted for in this retrospective study design.

Femoral bifurcation and tibial hemimelia are rare anomalies described as a variant of Gollop-Wolfgang complex. This article presents a case of Gollop-Wolfgang complex without hand ectrodactyly. A 5-year old patient presented with bilateral tibial hemimelia and left femoral bifurcation. The patient's left limb lacked knee extensor mechanism, disarticulation was done. The right leg which had Jones type 2 tibia hemimelia was treated with tibiofibular synostosis. Currently patient is ambulant with prosthesis on the left limb and ankle foot orthosis on the right. In the absence of proximal tibial anlage, especially in patients with femoral bifurcation, the knee should be disarticulated. Tibiofibular synostosis is a good choice in the presence of a proximal tibial anlage with good quadriceps function.

Although not as common as the other melanomas, amelanotic melanoma often evades diagnosis by masquerading as other pathology. A high index of suspicion is therefore required for early and appropriate intervention. We present a patient who was diagnosed and managed as having paronychia of the middle finger while in actual fact he had a subungual amelanotic melanoma. By the time of his referral to the orthopaedic team it had progressed to an advanced stage. Our case underlies the importance of early recognition and referral of this rare but malignant lesion by primary care physicians.
