Results obtained from an iterative statistical model found that at six and 12 months after operation, opening-wedge HTO caused increased anterior translation of the tibia (mean 2.6 mm, p\u00a0&lt; \u00a00.001), decreased proximal translation of the patella (mean \u20132.2\u00a0mm, p\u00a0&lt; \u00a00.001), decreased patellar spin (mean \u20131.4\u00b0, p &lt; 0.05), increased patellar tilt (mean 2.2\u00b0, p\u00a0&lt; 0.05) and changed three other parameters.
