The febella is a sesamoid bone in the musculotendinous junction of the lateral head of the gastrocnemius muscle, which is subject to injury and abnormalities. Should we remove or remain the fabella in total knee arthroplasy? Here we compared the impact of fabella removing or remaining on the clinical effects of total knee arthroplasty (TKA) of osteoarthritis (OA). From December, 2013 to March 2015, 200 Kellgren & Lawrence grade OA patients (200 knees) with fabella visible on pre-operation X-ray received TKA, whom were divided into fabella removing or fabella remaining group randomly. The length of surgical time, quantity of post-operation drainage, VAS scores (1 d, 2 d, 3 d, 1 w, 1 m and 3 m post-operation), HSS scores (1 w, 1 m and 3 m post-operation), posterolateral pain and palsy of common peroneal nerve post-operation were compared. The release of lateral structures was compared in the vegus. In cases of genu valgum, the release degree of the knee lateral structure was compared between the two groups. Two hundred patients (200 knees) were followed up from 3 to 6 months with an average 4 months. No significant difference was found in the length of surgical time, quantity of post-operation drainage, VAS and HSS scores between the two groups (P>0.05). The posterolateral pain and palsy of common peroneal nerve post-operation were only happened in fabella remaining group. More knee lateral structure release was needed in fabella remaining group in cases of genu valgum. Removing of fabella does not influence post-operation knee function but reduce the incidence of knee posterolateral complications and be helpful to the balance of soft tissue during operation in genu valgum cases.
