Clinical and functional outcome of metal backed versus all polyethylene post operated total knee replacement patients: a prospective study

<p class="abstract"><strong>Background:</strong> Osteoarthritis (OA) is most common chronic degenerative disease in orthopaedic practice. The literature pertaining to comparison of the clinical outcome and functional outcome between the metal backed and all polyethylene prosthesis for the total knee replacement are scant. </p><p class="abstract"><strong>Methods:</strong> A prospective study was undertaken in a tertiary hospital April 2018 to June 2019. The final sample size was 32 cases (40 knees) of newly diagnosed of primary OA knee cases treated with cemented TKR with Metal backed prosthesis and 29 cases (40 knees) with all polyethylene prosthesis. The patients were followed up at 1st, 3rd and 6th post-operative months.<strong></strong></p><p class="abstract"><strong>Results:</strong> Knee clinical score pre-op was not statistically significant. But after 1 month, after 3 months after 6 months, knee clinical score was statistically significant. Knee functional score pre-op, after 1 month, after 3 months, after 6 months was not statistically significant. 87% patients of metal back total knee replacement and 85% of all poly total knee replacement had no pain or just mild pain.</p><p class="abstract"><strong>Conclusions:</strong> Total knee arthroplasty resulted in excellent relief of pain, range of motion, restoration of function, and low prevalence of complications and continues to function well during the follow-up period. Improvement in clinical score in MB group is correlated significantly than all polyethylene group. Knee society scoring system is an effective in evaluating clinical, functional outcomes.</p>

Total Ossiculoplasty: Advantages of Two-Point Stabilization Technique

Objective. Evaluate a porous polyethylene prosthesis with two-point stabilization in total ossiculoplasty. This approach utilizes a lateral as well as a medial graft to stabilize a total ossicular prosthesis (TOP).Study Design. Retrospective cohort review of total ossiculoplasty.Methods. All patients who underwent total ossiculoplasty during the years 2004–2007 were included in the study group. Only five patients (10%) had primary surgery whereas 45 (90%) underwent revision surgery. Cartilage grafts covering the prosthesis (Sheehy, Xomed) laterally were used in all patients with areolar tissue being used for medial stabilization at the stapes footplate. Follow-up examination and audiometrics were performed a mean of 8.1 months following surgery.Results. The percentage of patients closing their ABG to within 10 dB was 44% with 66% closing their ABG to within 20 dB. The mean four-frequency hearing gain was 15.7 dB. The mean postoperative ABG was 15.7 dB.Conclusion. Audiometric results following total ossiculoplasty surgery using two-point stabilization exceeded results from the otologic literature. Proper two-point fixation with areolar tissue and stabilization utilizing cartilage were the keys to achieving a relatively high percentage of success in chronic ear disease in this sample.

Koenig total great toe implant. Preliminary report

A new first metatarsophalangeal joint implant arthroplasty is described. The two-component, titanium alloy and polyethylene prosthesis designed for weightbearing is noncemented and press-fit. Sixteen cases involving 18 implants were evaluated over 18 months with evidence that good correction and pain free motion can be obtained.

Porous Polyethylene Prosthesis: Continuing Experience

Members of the Otologic Medical Group have been using a porous polyethylene prosthesis since mid-1976. Several modifications of technique have evolved, which are described. Short-term hearing results are the same as with previous techniques, but they are more stable long term. Extrusion now occurs in approximately 5% of cases, usually due to a eustachian tube problem. In general we are pleased with our results and plan to continue to use these prostheses.
