Tibial Osteotomy in Gonarthrosis (Osteo-Arthritis of the Knee)

Technical Accuracy in High Tibial Osteotomy for Gonarthrosis

“…The effect of the operation is correlated with the correction obtained (Bauer et al 1969, Coventry 1965, Seal & Chan 1975.…”

The Effect of High Tibial Osteotomy on Pain in Osteoarthritis of the Knee Joint

“…Bauer et al (1969) found that the best results in terms of the patient's own total assessment were obtained when the femoro-tibia1 angle after the osteotomy was within the "normal" range of slight valgus (2-1 7 " ) . The statistical analysis of our results could not confirm this opinion.…”

“…This first promising report has been confirmed later by several clinical studies (Wardle 1962, Gothefors & Hult 1964, Coventry 1965, Helal 1965, Wiley 1967, Ahlberg et al 1968, Bauer et al 1969, Devas 1969, Goerttler & Debrunner 1969, Gunn 1969, Jackson et al 1969, Gagnaire et al 1970, Harris & Kostuik 1970. Harris & Kostuik (1970) summarized the prevailing opinions of operative techniques in the literature and recommended as the operative method of choice a high tibial wedge osteotomy proximal to the tibial tubercle.…”

“…The success of the osteotomy has been ascribed to the fact that the femoro-tibia1 axis was restored to the "normal angle of 2-17 degrees of valgus" (Bauer et al 1969).…”

Modified Loeffler's medial capsulotomy for osteoarthritis of the knee: 20 years' follow-up

“…The femorotibial angle (FTA) [5] was used as a parameter of varus deformity. The severity of medial compartmental knee osteoarthritis was evaluated according to modified Ahlbäck's criteria [1,14], and nine knees were classified as grade 2, and two as grade 1.…”
