BACKGROUND: Isolated involvement of the medial compartment of the knee in degenerative disease is encountered in about 25% of patients with gonarthrosis. We aim to show that in a well-selected group of such patients, medial unicompartmental knee arthroplasty (UKA) is a good option. OBJECTIVES: Review the functional outcomes of patients undergoing UKA and determine the long-term survivorship of the implants and complications of the procedure. DESIGN: Analytical retrospective chart review. SETTING: Academic tertiary care medical center and tertiary care private hospital in the western region of Saudi Arabia. PATIENTS AND METHODS: We selected patients who underwent medial UKAs by the same surgeon between December 1988 and December 2009. The life table approach and the Kaplan-Meier statistical method were used to estimate the survival rate (5–30 years) with revision as the endpoint. Functional outcome scores were determined according to the Knee Society Clinical Rating System. MAIN OUTCOME MEASURES: Change in performance scores for pain, walking, and range of movement. Survivorship of the implants with removal of the implant as the endpoint; post-operative complications. SAMPLE SIZE: 218 implants on 142 patients. RESULTS: The survival rate for UKA was 94.7% at 10 years (95% CI 0.906–0.970), 80.9% at 20 years (95%CI 0.724–0.871), and at 30 years it was 77.8% (95%CI 0.669–0.855) of the total knee arthropathies. The average grand total functional score increased from 61 (maximum 200) at 0 months to above 150 at ≥6 months. CONCLUSION: UKA is a good option for isolated medial compartment gonarthrosis with excellent functional outcome and good survivorship in selected patients. LIMITATION: Single center experience, retrospective. We lost 6.0% of patients during follow-up. CONFLICT OF INTEREST: None.

“…1 The purported aim of a UKA is to provide a restoration of knee function closer to a healthy non-surgical knee, compared to total knee arthroplasty (TKA) as the procedure requires less soft tissue dissection, and both cruciate ligaments can be preserved. 2,3 Thus, a shorter recovery period, 4 better clinical outcomes, like Knee Society scores, 5,6 comparable knee extensor strength, leg power and stair maneuver times, 7 and similar or better knee kinematics during gait 6,8,9 are expected for UKA as those reported in the literature. Moreover, evidence shows that UKA implants have comparable survivor rates with TKA 1,10-14 and lower revision rates.…”

“…29 There are only few biomechanical UKA investigations on stair ascent available. 7,27,30 UKA displayed a reduced range of knee flexion compared to healthy population. 27 However, implant designs and surgical procedures have changed since the study has been published.…”

“…Я к відомо, остеоартроз колінного суглоба є одним із найбільш розповсюджених дегенеративно-дистрофічних захворювань опорно-рухового апарату [1]. Актуальним на сьогодні залишається питання деформації колінного суглоба, яка виникає в результаті перенавантаження одного з відділів колінного суглоба [2,3,4,5]. В останні два-три десятиліття у світовій ортопедичній практиці "золотим стандартом" лікування таких пацієнтів є ендопротезування, яке забезпечує швидке відновлення функції суглоба, сприяє покращенню якості життя хворих [2,6,7].…”

Summary. In 67-72% of patients with gonarthrosis, there is an angular deviation of the tibia towards the lesion. Prolonged functioning in such conditions is accompanied by patellofemoral arthrosis, in the development of which we found patterns during unicompartmental arthroplasty of the knee joint. Materials and Methods. This publication is based on the materials of a clinical and radiological examination of 106 patients with angular deviation of the tibia who were operated on using the method of unicompartmental arthroplasty. Conclusions. The degree of patellofemoral osteoarthritis is directly dependent on the duration of the disease and the magnitude of the angular deviation of the tibia. The most degenerative-dystrophic changes occur in the knee facet and the central facet, which are displaced in the projection of the patellofemoral joint, where cartilage degeneration, subchondral sclerosis with foci of bone destruction, pronounced marginal bone growths, and exostoses progress.

Abstract: We suggest that UKA is a satisfactory treatment in regard to the recovery of knee strength, leg power and ability to climb up and down stairs.
