Comparison of Pre- and Postoperative Motor-proprioceptive Abilities in Patients with Gonarthrosis.

Both surgeons and patients want to achieve a high level of satisfaction and the best possible functional results within a short time after knee TEP surgery. By using a tool that digitally records various measurement parameters of balance and motor function preoperatively and postoperatively on a mobile basis and with little time expenditure, progressive results can be compared. Individual factors can thus be determined and these can influence the progress in regeneration and training progress perioperatively.

Digital Measurement of Individual Motor and Proprioceptive Skills in Patients with Osteoarthritis of the Knee Prior to Total Knee Replacement.

Purpose: In spite of consistent improvement in operative methods for total knee arthroplasty, individual motor deficits may lead to a lower outcome. The preoperative classification in individual motoric capacity may get more significance for the future. Complementary to established questionnaires and clinical tests, this pilot study should demonstrate that it is possible to generate a preoperative motor score using a force platform measurement (KMP).

Prospective pilot study to identify psychological factors influencing peri-operative pain in total knee arthroplasty (TKA).

Purpose: Up to 20% of total knee arthroplasty (TKA) patients remain dissatisfied, with chronic pain as the most frequently named cause. A pilot study was conducted to assess the progression of peri-operative pain intensity and the parallel development of different psychological factors and coping strategies, as well as correlations indicating potential inter-relationships.

Methods: Pain, psychological impairment [FESV BE], and coping strategies [FESV BW] were assessed before and after TKA [days - 5 to 31].

Collagen and proteoglycan turnover in focally damaged human ankle cartilage: evidence for a generalized response and active matrix remodeling across the entire joint surface.

Objective: Although cartilage lesions occur in the ankles, osteoarthritis rarely develops in the ankles, suggesting that ankle cartilage can up-regulate mechanisms to repair the damaged matrix. To define these processes, we compared cartilage samples obtained from normal tali and from lesional sites of damaged tali.

Methods: Cartilage samples were obtained from the tali of normal ankles and from 3 sites on tali with lesions (the lesion, adjacent to the lesion, and far removed from the lesion).

First metatarsophalangeal joint replacement: the method of choice for end-stage hallux rigidus?

Replacement of the first metatarsophalangeal (MTP) joint remains critical because of complex biomechanical conditions and implant fixation. After a 3-year follow-up, most patients who experienced an MTP joint replacement were extremely satisfied with the outcome. Plantar pressure distribution revealed a marked improvement.
