Minimally invasive Oxford medial unicompartmental knee arthroplasty. A note of caution!

We present the peak outcome results of the Oxford medial unicompartmental arthroplasty through a minimally invasive surgical incision. This prospective study included 78 Oxford medial unicompartmental knee replacements in 68 patients. At the 2 year review the patients achieved a mean Oxford Knee Score of 38.3. This was not significantly different to the 2 year results of the phase 2 Oxford knee carried out using a standard parapatellar approach when patients achieved a mean OKS of 36.0. Four unicompartmental knee replacements required revision for unexplained pain, deep infection, aseptic loosening and bearing dislocation. Minimally invasive joint replacement is attractive to both patients and surgeons, but is technically demanding with complications inherent to limited access.

The effect of preoperative symptom severity on functional outcome of total knee replacement--patients with the lowest preoperative scores achieve the lowest marks.

To determine if the functional outcome of total knee replacement (TKR) was affected by the level of preoperative symptom severity, the association between preoperative Oxford Knee Scores (OKS), and 2 year OKS, American Knee Society clinical and function scores (AKSS) was assessed. Data were prospectively collected on 45 cases who had single joint osteoarthritis and no other comorbidities. We have specifically focused on patients with single knee involvement to remove the effect of multiple joint involvement and comorbidities on the OKS. The mean preoperative OKS was 21.4, postoperative OKS 40.0 and postoperative ROM 117 degrees. The postoperative mean AKSS was 86.7 and mean function score was 85.0. The 'usual pain' and 'limp' components of the OKS had the greatest rises and the 'kneel' component had the least improvement. Rather than all patients achieving uniform results post-TKR, patients with more severe symptoms achieved poorer absolute outcomes. The Spearman correlation coefficient between pre- and postoperative OKS was r = 0.4 (p = 0.006). Although the results suggest that waiting too long before intervention compromises the final outcome, a correlation of 0.4 is not strong enough to necessitate change in current practice.

The three in one procedure: how I do it.

Recurrent patella dislocation is common, and selection of an appropriate stabilisation procedure is important for a successful outcome. We describe a combined proximal and distal realignment procedure to adjust soft tissue tension around the patella. This procedure, the 'Three in One' involves a combination of a lateral release, vastus medialis obliquus muscle advancement, and transfer of the medial third of the patellar tendon to the medial collateral ligament. This is a safe, reliable procedure for patients with recurrent dislocation of the patella resulting from an imbalance of soft tissue tension around the patella, but with a normally sited patella and normal trochlea.
