Complex primary total knee replacements have been poorly reported in the literature We review all complex primary total knee replacement procedures at Stepping Hill Hospital. Patients underwent knee examination, knee scores, notes review and pre- and post-operative radiograph review. There were 29 patients with 36 knees that had a complex primary total knee replacement. Most frequent indications for surgery were osteoarthritis, rheumatoid arthritis or following trauma. Mean age at surgery 70 years. The prosthesis used were : 3 Stryker Kinemax; 32 De Puy PFC and one rotating hinge. Complex Primary Oxford knee score; preoperative mean 45 (range 33 to 57); postoperative mean 26 (range 14 to 53). NJR Total Knee Replacement Oxford knee score postoperative mean 30. Mean visual analogue scores; pain in the knee, mean 19; knee function, mean 77; outcome of the operation 76; satisfaction with the surgery 87. Mean length of hospital stay 13 days. Using the Knee Society Radiographic Scoring System, there were no signs that need to be monitored or signify failure. Seven patients were transfused postoperatively, four patients had minor wound problems, three required further surgery, two to washout the knee and exchange the polyethylene liner, one femoral plating to stabilise an osteotomy site. Long term complications : one above knee amputation for infection, one foot drop. Revision implants can be used in complex primary knee replacements, and pose technical difficulties but address various pathologies. The surgery is associated with an increased risk of complications and transfusion. Clinical scores at least match scores for routine total knee replacements, patient satisfaction is excellent.
We present our results in 89 consecutive patients (138 feet), minimum FU of 24/12.
Contraindications included abnormal DMMA, significant 1st MTP arthritis, hypermobility of 1st MTC joint, revision surgery. All patients underwent a 3-in-1 procedure with soft tissue release in 1stwebspace, medial bunionectomy with capsulorraphy and basal crescentic osteotomy. A 25 mm blade on oscillating driver was used. Fixation was staples(70%),screws(20%),K- wires(10%). Post op, PWB, progressing to FWB at 3/52. AOFAS forefoot scores at pre-op, 6/12, 12/12 and 24/12. Weight bearing radiographs obtained at pre-op, 3/12, 12/12.
M:F=19:70 Age 31–79 (Mean 64) 89 patients, 138 feet AOFAS scores improved from average 42/100 preop to 76/100 at 6/12. Radiographic correction excellent in78% of patients. 74 % of patients extremely satisfied,15 %satisfied,11 %unsatisfied with outcome.

Subtalar joint stiffness is an under recognized complication of ankle fractures. We set out to objectively measure its prevalence and impact on Activities of Daily Living (ADL).
60 ankle fractures included in study. All patients had contralateral normal ankle. M:F=21:39 Average age: 36 (19 – 84) Weber: A B C 21 27 12 27 patients underwent ORIF (12C + 15B) 39 patients had plaster casts for between 2 and 6 weeks. (27B + 12C) Postop regimes included early mobilization and POP application (AO recommendation) Weber A (21) treated symptomatically. Examinations for study at 3/12 and 6/12 post injury. Subtalar and ankle movements were assessed by the same examiner (as per Hoppenfeld) Subjective questions about subtalar stiffness and their impact on ADL were asked.
At 3/12, 56 patients (17A + 27B + 12C) had subjective and clinical impairment of subtalar movement. 32 patients (2A + 20B + 10C) had moderate to severe impairment (>
30%) At 6/12, 42 patients (9A + 23B + 10C) had subjective symptoms and clinical impairment of subtalar function. Of these, 26 (0A + 18B + 8C) had >
30% impairment vs. controls.
We present our results with a modified Mann-Thompson procedure in 47 patients (86 feet). Minimum follow up was 24 months. All patients had moderate to advanced forefoot deformities.
M:F=12:35 43/47 bilateral Simultaneous procedures in bilateral cases. Popliteal block analgesia used routinely.
Medial incision centered on MTP1 joint. Minimal bony and soft tissue resection. Fixation carried out with staples (78 feet),K-wires (8 feet) Transverse incision centered on the lesser MTP joints made. Combination of soft tissue release, lesser MT head resection in cascade fashion from dorsal distal to proximal plantar performed. Lesser toe deformities treated by a combination of closed osteoclasis, soft tissue release and bony resection. Transarticular K-wire fixation then performed for all lesser toes. Bulky postop dressing and post op shoes used. Immediate FWB permitted. Transarticular K-wires removed at 4/52.
AOFAS Forefoot Scores assessed at preop,6/12,12/ 12,and24/12. Subjective patient assessment of procedure requested. Average AOFAS scores improved from 37to72(67 – 84) 40 patients extremely pleased with the results. 5 patients pleased with reservations and 2 patients disappointed with the outcome.
3 superficial wound infections 2 metal work related problems 2 early loss of lesser toe correction 3 late deformities of lesser metatarsals requiring surgery
